Adam Garza: Plumbing Pride

By James Florence, Diamond Certified Resource Reporter

SAN JOSE — Adam Garza learned about plumbing from his father while he was growing up, but it wasn’t until later in life that he acquired a sense of pride in the family trade. “My father has been a plumber for 35 years, and he started San Jose Plumbing back in 1991,” he details. “As a kid, I used to ride around with him and he would teach me about the trade. However, it wasn’t something I wanted to do for a living—after all, not too many eight-year-olds aspire to become plumbers.”

Following high school, Adam enrolled at a local junior college, unsure of his professional path but confident it wouldn’t involve plumbing. However, when a family emergency struck, he suddenly found himself in the thick of it. “During my second year of junior college, my dad fell ill,” he recounts. “There’s nothing I wouldn’t do for my family, so when he asked if I’d come on board and help out with the business, I dropped out of school and came to work.” Not long after getting into plumbing full-time, Adam noticed an unexpected development. “Somewhere along the way, I learned to really enjoy plumbing. I liked the fact that every day was different, and I enjoyed working with my hands and helping people. After my dad regained his health and returned to work, I decided to stick with it. Twenty years later, it’s turned out to be a great career for me.”

Today, Adam says his favorite part of his job is the opportunity to help others. “It feels really good to have a job where I get to help people every day. A lot of our jobs are emergency situations, so it’s very rewarding to show up, assure the customer that everything is under control and see them breathe a sigh of relief.”

A resident of Gilroy (where he lives with his wife, Mia, and their three children), Adam expresses an appreciation for his local community. “I was born and raised in San Jose, so I feel like I’m very much a part of this community,” he says. “I take a lot of pride in being able to serve my friends and neighbors.”

Outside of work, Adam likes to stay active with physical exercise and outdoor activities. “My job is very physically demanding, so I like to stay in shape by working out, running and mountain biking,” he affirms. “I also enjoy going camping with my family. We’re very outdoorsy, so we spend a lot of time in Tahoe going hiking and stuff like that.”

In his life and career, Adam espouses the importance of communication. “Communication is central to any good relationship, whether it’s with your family, your staff or your customers,” he asserts. “When there’s clear communication, everything is out in the open and expectations are real, but when there isn’t, it really limits your potential, so I always make an effort to keep those lines open.”

When asked the first thing he’d do if he were to retire tomorrow, Adam says he’d book an extended stay at his family’s favorite vacation spot. “I’d probably spend a summer at Tahoe with my family. We love it there and try to go a few times a year, so it would be a blast to do the whole summer!”

Frans Cartwright: Recapturing Fulfillment

By James Florence, Diamond Certified Resource Reporter

SAN JOSE — After finding himself at a professional impasse, Frans Cartwright was considering his options when inspiration came from an unlikely source. “After several years as an engineer in the tech field, I started to feel unsatisfied with my work and was figuring out what I wanted to do,” he remembers. “One day, we had a plumber come out to replace our water heater, and I was struck with the notion that I could do water heater installation as a small business venture. After doing a little research, I decided to go to work for a local plumbing company, which enabled me to gain experience while I studied to get my plumbing license. Within a couple of years, I was ready to launch my own water heater installation company.”

Since founding Better Water Heaters in 2003, Frans says he’s recaptured the sense of fulfillment that had been missing from his prior occupation. “I really enjoy the problem-solving aspect of the trade because it allows me to exercise my engineering skills. However, I also appreciate the opportunity to interact with and take care of my customers, which is something that had never been a part of my former career. Altogether, it’s been a very satisfying experience.”

Originally from Southern California, Frans moved to San Jose in 1996, where he currently lives with his wife, Melinda, and their five children. “San Jose is a great place to raise a family, with a lot to do locally and many nearby national parks for spending time in nature,” he says. “In addition to attending different local events and festivals, we enjoy going camping at places like Yosemite and Big Sur, as well as skiing at Lake Tahoe.”

In keeping with his values as a devoted family man, Frans has made it a point to create a family-centered culture at Better Water Heaters. “I’m all about family, and that’s the type of environment we foster here,” he affirms. “A lot of my employees have kids, so I try to be accommodating with scheduling so they can take time off for family things. Obviously, making a living is important, but I think being there for your family is an equal priority.”

When asked what his future retirement might look like, Frans says it will hopefully involve plenty of exotic locales and fine foods. “My wife and I are foodies, and we also love to travel, so that will probably be the focal point of our post-retirement ventures. It’s been quite a few years since we’ve been to Europe, so we’d probably kick things off with a trip to France or Germany.”

Yussef Nesme: Expanding His Horizons

By James Florence, Diamond Certified Resource Reporter

SAN JOSE – While landscaping and plumbing may seem like completely different industries to many people, for Yussef Nesme and his career path, one led to the other. “I started out in landscape design,” he explains. “It seemed to me that plumbing was pretty similar to landscape irrigation, and since plumbing is something everyone needs, I decided going into that industry would be a good career move.” Today, as Marketing Director of Rayne Plumbing and Sewer Service, Inc., Yussef enjoys the professional diversity that his position allows. “I love every aspect of my job, whether it’s meeting with people and building relationships on the sales and marketing side or working with my hands in the field.”

A lifetime resident of the Bay Area, Yussef says he appreciates living in what he considers the “capital of technology.” “In terms of technological innovation, the Bay Area is where the action is, so it’s exciting to be a part of that. Our area is both home to some of the major technological leaders and innovators and the place where all the new startups want to come to get established.”

When he’s not working, Yussef likes engaging in a number of sports-related activities, including playing pick-up basketball, snowboarding, jet skiing and training mixed martial arts. He also enjoys spending time with his mother and sisters, as well as his dog, Capone, a 150-pound boxer-pitbull mix.

Throughout his career, Yussef has learned the value of the age-old maxim: the customer is always right. “A lot of times, people will get carried away trying to convince somebody else that they’re right,” he explains. “But the amount of energy, time and frustration involved is rarely worth whatever they’re arguing about. As a professional, I’ve found it’s much more beneficial to avoid arguments altogether and just do what I need to do to make the customer happy.”

When asked the first thing he’d do if he could retire tomorrow, Yussef expresses a desire to expand his horizons. “I’d travel the world,” he says. “I’d especially like to visit Greece—besides the historical sights, I’ve been told it’s gorgeous and the people live really simply, which sounds like it’s right up my alley.”

Jin Lee: Plumbing Smarts

By James Florence, Diamond Certified Resource Reporter

SANTA CLARA — Jin Lee has always possessed a mechanical mind, so it only made sense for him to enter a field where he could utilize its full potential. “As a child, I was fascinated with how things worked and was always taking things apart and putting them back together,” he remembers. “Not surprisingly, plumbing was something that really interested me. Later, while working in furniture manufacturing, I did plumbing on the side as a hobby. When I came to the United States in 1995, I finally got a chance to pursue plumbing as a career, and in 2002, I started my own business.”

Today, as owner of Smart Plumbers, Inc., Jin says his favorite part of his job is bailing customers out of bad situations. “When someone is without water or can’t use their toilet, it’s not just an inconvenience—it’s an emergency. When I’m able to fix the problem and restore their plumbing system, they tend to be extra appreciative, which is very rewarding.”

Originally from South Korea, Jin now resides in Santa Clara with his wife, Sylvia. Outside of work, his favorite hobby is playing golf. “I try to golf at least once a week” he affirms. “Sometimes I don’t have time, but I do my best to make it happen.” Jin also enjoys following professional sports like football and soccer, as well as spending time with his children and grandchildren.

In regard to his professional career, Jin emphasizes the foundational importance of sanitation. “Modern plumbing originated because of a need for sanitation, and that’s still one of its most important aspects,” he explains. “Unfortunately, some plumbers and handymen neglect this, which can lead to unsanitary conditions and consequent health hazards. As far as my company is concerned, sanitation is a top priority—we always make sure our customers’ plumbing is clean, safe and secure.”

When asked what his life might look like if he retired tomorrow, Jin says he would spend more time doing the things he currently enjoys. “I would definitely play more golf—I’d probably go from playing once a week to playing every other day. And, of course, I’d spend more time with my wife, kids and grandkids.”

Steve Schafer: A Helping Heart

By James Florence, Diamond Certified Resource Reporter

When Steve Schafer first got into plumbing, he was merely looking for a steady paycheck, but in the end, his career turned out to be more rewarding than he’d ever expected. “After being in construction for several years, I suddenly found myself out of work,” he remembers. “I heard that plumbers made pretty good money, so I applied for a job. After I got started, I found that I really enjoyed it. I especially liked the fact that I got to help people every day. I also enjoyed the problem-solving aspect. It wasn’t all leaky faucets—I really had to use my brain!”

Not long after starting in the industry, Steve got hired at Allstar Plumbing, where he continues to work 20 years later as a manager. After more than two decades as a plumbing professional, Steve says his favorite part of his job is still the opportunity to help people. “I enjoy being able to come out and ‘save the day’ for our customers. It’s always rewarding to bail someone out of a tough situation, and that’s what we get to do every day.”

A resident of Willow Glen, Steve expresses his appreciation for the positive attributes of his locale. “The weather is beautiful here and it’s a really diverse area. Being a suburb of San Jose, it’s not quite the city and not quite the country, so it’s a nice mixture. Plus, there’s a lot of old plumbing to fix, so there’s job security.”

Outside of work, Steve engages in a variety of hobbies and pastimes. “I like watching movies, playing guitar and hanging out with my dog, Zoey,” he says. “I also enjoy fishing and getting out and exploring the Bay Area—there’s certainly a lot to see.” Additionally, Steve likes to stay in touch with his daughter, Tyler, who resides in Washington.

In his life and career, Steve says his passion for helping others goes beyond being on the clock. “Besides helping people in our work, some of the other Allstar employees and I are involved with charitable causes like Sacred Heart’s Pack a Back program and Operation ELF. We also hold fundraising events for various charity organizations—things like barbecues, car washes and poker tournaments. That way, we’re able to both help people with their plumbing problems and make a difference in the lives of those less fortunate in our community.”

  • How To Work With
    Encourage the Best Plumbers in Santa Clara County to Bid on Your Job

    Some homeowners have found it’s smart to hire a plumber for smaller projects before signing a contract for a major plumbing repairs or installation. Others like having a working relationship with a local plumbing contractor because it gives them the confidence to know who to call in a plumbing emergency.

    It’s important to know that some good plumbing contractors in Santa Clara County are choosy about which jobs they accept. This is because bids take time and expense to prepare, and some of these local plumbers have been taken advantage of by unreasonable homeowners.

    How can you encourage the best plumbing contractors to be interested in your job?

    • Show the plumbers you interview that you’re interested in a good value, not just the lowest bid. Oftentimes, the first questions plumbing contractors hear from potential customers is about the cost of a job. You can show them you know what’s really important in a plumbing installation and repair by asking about quality products, knowledgeable installation and overall value.
    • Be honest if you’re interviewing a few plumbers, but assure each that you’re accepting bids from a few select companies, not dozens.
    • Interview and hire local plumbing companies in Santa Clara County including the larger cities of San Jose, Mountain View, Sunnyvale, Santa Clara and Milpitas. Most plumbers like to work in the local area, since it allows them to provide more timely service. It also helps you weed out less reliable plumbing contractors who travel long distances and install discounted products at a cut-rate that local contractors may not be able to compete with price-wise.
    • Be upfront about your needs and desires for your plumbing repairs or new plumbing installation. The more you share with your plumbing contractor, the easier it is for them to give you a reliable bid, the right plumbing services, and the follow-up service you need.

    Get a Contract that Protects You and Your Contractor
    Congratulations! You’ve found a good plumbing company that meets all of your requirements. Whether you’ve chosen a plumber from the larger cities of San Jose, Sunnyvale, Santa Clara, Mountain View, Milpitas, Palo Alto, Cupertino, Gilroy, Campbell and Morgan Hill or a smaller town, now is the time to request a contract for the work desired.

    The contract should include in detail the scope of the plumbing project, any items or services that are excluded, payment terms, the exact plumbing materials and products to be used and any warrantees and guarantees. Your plumber should be proud to install only the best plumbing products and materials. Often, especially with plumbing fixtures, you will recognize the brand names of the best manufacturers. You may pay more for these plumbing products initially, but installing quality plumbing materials can save you money in plumbing repairs and replacements in the future.

    Once your plumber has given you a contract, read it entirely and be sure you understand all the terms and exclusions before signing it. This contract will protect you and your property, as well as your local plumber. So never sign a blank or incomplete estimate. You may write in additional requests or verbal agreements you’ve come to with the plumbing company representative, including start and end dates, no-later-than clauses that stipulate the date by which all work must be completed, or any bonuses you want to offer for early completion.

  • Be a Good Customer
    Simplify the Job for Your Santa Clara County Plumbing Company

    One of the easiest ways to get the most out of your contract with a local plumbing contractor is to be organized. This way, you can save the plumber time and save yourself money. You can reduce the billable time by having a written list of specific items you want addressed and a list of questions or concerns you want to talk about with your plumbing contractor.

    If you have a leaky sink or under-counter pipe leak, move all household items from the area so the plumber doesn’t have to spend his or her time clearing a space in which to work.

    Keep children and pets away from the area where the plumbing contractor is working for their safety and the safety and convenience of the plumber.

    Ask your plumbing company representative if there is anything you can do to help speed the job along. They may have specific suggestions of steps you can take to aid the plumbing repairs or new plumbing fixture installation and to shorten the duration of the job.

    How Can You Be a Good Plumbing Company Customer?
    It’s your plumber’s responsibility install quality plumbing systems and fixtures using the best possible techniques. But you play a big part in the success of your plumbing repairs and installations, too.

    • Be sure your Santa Clara County plumbing service has a phone number where they can reach you at all times during the course of the work.

Check The Work
Compare the Invoice with the Completed Plumbing Work

When your plumber has completed the work and before they leave the premises, most good plumbing companies will give you a written invoice for the work done. This invoice usually includes the following:

  • The name, physical address and license number of the plumbing firm.
  • A complete list of all work performed.
  • An itemized list of all new plumbing fixtures, materials and replacement parts.
  • The total cost, including the amount due for labor and plumbing materials.
  • Any applicable warrantees or guarantees provided by the plumbing product manufacturers and the plumbing company.

It’s smart to compare the work that was actually done to the written invoice. Ask your plumbing company representative to accompany you on a walk through the job site and show you the plumbing repairs or new plumbing installations. Check the work completed against the invoice.

During your walk-through, ask if there are any special instructions for operating your new plumbing fixtures and the best steps to take in maintaining them. If you have questions about what work was done or how the installation was completed, ask your plumber before he or she leaves the job site.

Frequently Asked Questions
Frequently Asked Questions About Plumbing Services

Read on to find the answers to the most commonly asked of and about plumbing contractors.

Q: Why choose a Diamond Certified Plumbers?

Only plumbers rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with in-depth and ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified plumbing contractor.

Q: Why won’t some plumbers in Santa Clara County give estimates over the phone?
A: Many good plumbers won’t give estimates over the phone because it can be hard or impossible to accurately diagnose a plumbing problem without seeing it first-hand. Since plumbing fixtures and materials greatly vary, plumbing contractors who give estimates over the phone may end up changing the diagnosis and the fee after arrive on the site to repair the problem or install the fixtures.

However, many plumbers will give free estimates when they come to look at the plumbing problem in person. Others may charge for estimates but might apply the fee toward your repair costs if you hire them to do the plumbing repairs.

Q: Is it an advantage to hire a Santa Clara County plumber who carries parts and equipment in their work trucks?
A: It can be an advantage to hire plumbing companies who has a well-stocked work truck. These prepared plumbers can usually repair common plumbing problems faster because they have with them all the materials required, rather than having to drive to a plumbing supply store.

Q: My plumber wants me to sign a Waiver of Right to Cancel for my emergency plumbing repairs. What is this and is it legal?
A: In the state of California, consumers who sign a contract with a company that comes to their home to provide a service or product have three days to cancel the transaction. However, while that might be a protection for the consumer in some cases, it can cost plumbers thousands of dollars if a consumer decides to cancel the contract after an emergency plumbing service has been rendered. That’s because unlike products, consumers can’t return services, so if a customer cancels the transaction, the plumber will have, in essence, don all the work for free.

For that reason, some plumbers ask emergency plumbing customers to sign a Waiver of Right to Cancel, meaning that they accept and will pay the charges for the emergency plumbing repairs. Asking a customer to sign this waiver is legal, but only if the repairs are for a true emergency. To protect yourself from plumbers who try to take advantage of customers by asking them to sign a waiver in a non-emergency situation, make sure the repairs you’re having done are truly required immediately.

Q: How can I prevent drain clogs?
A: Frequently hiring a plumber to unclog your drains can get to be expensive. If you find yourself regularly calling your plumber to fix clogged drains, there are some simple solutions that can help you avoid trouble in the future.

  • First, find out what type of pipes you have. Older pipes such as iron pipes or galvanized pipes can rust and clog more easily. You may choose to hire a local plumbing company to repipe your home using copper or PVC pipes, which are less likely to clog and will not rust.
  • Install stoppers and hair traps on all your sinks and bathtubs.
  • Do not pour cooking grease or other liquids down your sinks that may solidify when cool.
  • Regularly flush sinks and bathtubs with running water.
  • Remove hair and other debris from sink stoppers before it can be flushed down the drains.
  • Never use your toilet as a garbage disposal or flush baby wipes or paper towels.

Q: We rarely use our guest bathroom. Is there anything we should do to keep the plumbing and fixtures working?
A: Toilets, piping and fixtures should be regularly flushed with water. This keeps the water traps full and avoids the backflow of odors and gasses into the home. Once a week, you should use or turn on the fixtures to keep them functioning. You can also pour a bucket of water in each toilet, sink, shower and floor drain in the unused bathrooms in your home.

Q: What are on-demand water heaters?
A: On-demand water heaters, also called tankless water heaters, heat water as you use it rather than heating and storing hot water in a tank. Because tankless water heaters don’t waste energy storing and maintaining the temperature of unneeded hot water, their operating costs can be up to 30 percent lower than those of a traditional water heater. And with the emphasis on energy-saving appliances, tax credits may be available to consumers purchasing an on-demand water heater.

Q: Should I buy a low-flow showerhead or low-flush toilet? Why?
A: Low-flow plumbing fixtures like low-flow toilets and low-flow showerheads save substantial amounts of water over traditional showerheads and toilets. This saves water, energy and expense. Numerous water-saving fixtures have been available since the National Energy Policy Act that mandated low-flow toilets was passed in 1995. While some consumers complained that early models of low-water fixtures had weak pressure and didn’t work as well as the standard fixtures, modern

Q: What other water saving and energy saving plumbing fixtures are available in Santa Clara County?
A: These days, there are many options for energy-saving plumbing fixtures, or green plumbing solutions. Some include air-assisted toilets, gravity toilets, power-assisted toilets, aerators, green plumbing fixtures, tankless water heaters, gray water recycling fixtures, composting toilets, dual-flush toilets, waterless urinals, sensor-operated faucets, solar water heaters, hot water re-circulating pumps and many others. Call your local plumbing contractor in Santa Clara County for more information on available water-saving plumbing products and which ones will work best for you.

Q: My drains are running slow. Can I use a Liquid Plumber-type drain cleaner to clean out the pipes?
A: You may be able to fix clogged drains and stopped up sinks by using drain-cleaning chemicals you buy at the store or a non-toxic baking soda drain cleaner. However, for tough clogs that you can’t clear after a few attempts or drains and pipes that clog constantly, you may need to call a Santa Clara County plumbing company to professionally remove the clog or snake out your pipes and drains to keep clogs from forming in the future.

Q: I think tree roots may be growing in our pipes. What should I do?
A: First, have a good plumber confirm that you have roots in your piping. Some plumbers in Santa Clara County have camera equipment that can prove where the problem is, that it is roots growing in the pipes, and can give them a view of how to repair the problem. They can also advise you on the best method to prevent the problem. This may entail removing the bushes or trees that are growing into the piping, using a root-killing product, replacing the affected pipe with a stronger material, or snaking out the pipe or using high-pressure water to jet out the pipe and line it with an epoxy material.
