Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for plumbing companies that have earned the prestigious Diamond Certified award. For Absolute Plumbing and Drain, the best way to keep customers satisfied is to take an honest, informative approach to their jobs. “We lay out all of the information before our customers make any decisions,” says owner Rod Tehrani. “They really like that type of honesty. We just want our customers to be informed—most of the time, our work is concealed underground or inside walls, so we believe they deserve to have as much information as we can give them.”

Absolute Plumbing and Drain has been providing plumbing services for residential and commercial clients in Contra Costa County, Solano County, and parts of Alameda County since 2002. The company has the in-house capabilities to install and repair everything from sewer and gas lines to fixtures and water heaters, and it also offers 24/7 emergency service for the convenience of its customers.

In contrast to many of its competitors, Absolute Plumbing and Drain appreciates the challenges of atypical jobs. “We really like troubleshooting,” affirms Mr. Tehrani. “Finding solutions to complex problems keeps us fresh and engaged with our work. We always say, ‘Leave the hard jobs for us.’ We’ll crawl underneath a house to solve a problem that three other companies weren’t able to fix.”

Another distinguishing attribute of Absolute Plumbing and Drain is its refusal to engage in high-pressure sales tactics. “We aren’t in business to compete, and our employees are never pressured to sell products or services to get ahead,” explains Mr. Tehrani. “That might not be a popular business model, but we’re proud of it. We use quality parts, choose materials made in the United States whenever possible and treat our customers like family.”

Industry Info

When it comes to hiring a plumbing company, it’s smart to shop for quality and value.

Many people who have problems with their faucets or toilets are tempted to call a plumbing company that offers the lowest bid, but experts say you won’t do yourself any favors by blindly choosing the cheapest plumber. In fact, according to Rod Tehrani, owner of Absolute Plumbing and Drain in Concord, the most important thing homeowners should know about the plumbing industry has to do with cost. “You shouldn’t go with the cheapest plumber because you’re going to pay for it later,” he says.

But that doesn’t mean you need to go with the most expensive company, either. According to Mr. Tehrani, it all comes down to finding the right fit for your job. “If you want to replace a fixture and have the time, you can educate yourself and choose the right person for your project.”

Mr. Tehrani says that’s particularly important for avoiding fly-by-night companies that bring employees into the area from other towns, stay in cheap hotels for a few days or weeks, and make money by doing a lot of cut-rate jobs before moving on to another area. While their rates may seem unbeatable and they don’t advertise the fact that they’re not local, consumers who choose to hire these companies can find themselves stuck when their jobs fail or they need to make warranty claims. Not only that, they have to hire another plumber to fix the job, effectively paying for it twice. And if the work wasn’t up to code, they could be liable for repairs or replacements if they try to sell their homes.

Instead, Mr. Tehrani recommends doing some research about your plumbing needs by calling local city or county agencies for information. “Those inspectors have tons of knowledge, and they hear stories every day,” he shares. “They’re some of the best people to call for advice. They can’t refer you to a company, but they can educate you regarding your situation.”

Frequently Asked Questions

Q: What kinds of pipe fittings do you use?
A: We use technology that’s new to the United States. It has been used in Europe for decades, but we’re one of the first companies in the Bay Area to use it. Instead of using heat and soldering the parts, we utilize a system that uses more than 4,000 PSI to press the fitting over the pipe.

Q: What materials and products do you use?
A: We always try to use quality products that are made in the United States. If we can’t find the part we need from an American supplier, we use something from Germany or Canada. All of the fittings we use on our copper or PEX pipes are from Germany, and our pipes are made in the United States.

Q: Do I need a permit for my plumbing job?
A: Most replacement work is done with a permit. We’ll pull permits through the city or county for anything we replace or alter.

Q: Can you perform real estate plumbing inspections?
A: Yes. We’ll camera-inspect the sewer line and the storm drain line to verify the condition of the pipes. It’s an expensive repair or replacement, so people who are buying homes want to know if their pipes are in good condition.

Q: Can I trust your employees?
A: Absolutely. Our employees have all passed background checks, and they wear clean uniforms so you can identify them as employees of our company. Also, most of them go through training and classes every three months in order to be certified or improve their knowledge about new products on the market.

Q: Do you offer financing?
A: Yes, depending on the job. We work with three different banks, and some of them have low interest rates that can help customers get their problems fixed right away. There are different terms depending on your credit and the plan you choose, including three months with no interest; six months with no interest; and one-, five-, and seven-year plans. In many cases, it only takes 10 minutes to secure financing because our technicians carry iPads with software that lets them submit financing paperwork. As soon as it’s accepted, we can move forward with the job.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Rod Tehrani

Rod Tehrani: A Technical Advancement

By James Florence, Diamond Certified Resource Reporter

CONCORD — After eight years of working construction, Rod Tehrani felt it was time to advance to something a little more technical. “I decided to look into plumbing,” he relates. “At first, it was a lot more grunt work than technical, but that changed with time. The more I learned about the intricate aspects of the profession, the more I enjoyed it. Eventually, I got hired by the county as a crew leader for underground pipe replacement projects. In 2002, I started my own plumbing business, and it has been growing ever since.”

Today, as owner of Absolute Plumbing and Drain, Rod says his favorite part of his job is the daily challenges. “Every day brings new situations and new problems to solve. Even if the job is basically the same, the unique situation can differ significantly. I enjoy troubleshooting and finding solutions to challenging problems.”

Originally from Iran, Rod came to the United States in 1995 and currently resides in the East Bay Area. “Transitioning from life in Iran to life in the U.S. wasn’t exactly smooth,” he says. “I had a business degree, but back then it wasn’t recognized in the U.S., so I basically had to start over from scratch. What I appreciated most was the fact that I was accepted here, despite being from a totally different culture. I will always be appreciative of the people who accepted me for who I am and helped me get on my feet.”

In regard to his professional career, Rod espouses the importance of going the extra mile to ensure customer satisfaction. “I’m not worried about being the biggest or most profitable plumbing company; I’m more concerned about making our customers happy,” he affirms. “Sometimes that means going the extra mile. For example, I recently did a job where I was at the customers’ home until 9:30pm, just so I could make sure they had running water before I left. They couldn’t believe I was willing to stay that long, but they were very appreciative. Driving home, I was tired but happy. That’s the kind of feeling that’s more rewarding than money.”

When asked the first thing he’d do if he were to retire tomorrow, Rod says he’d take a cruise. “I work six days a week, so if I retired, I’d definitely take some time to relax. Maybe I’d go on a cruise to Costa Rica. Of course, I’d want to keep the business running with my guys, so I probably wouldn’t retire completely. Maybe I’d just transition into a less hands-on role.”

Ask Me Anything!

Q: What’s your favorite restaurant?
A: The Cheesecake Factory in Walnut Creek.

Q: Music or talk radio?
A: Talk radio.

Q: Do you collect anything?
A: Watches.

Q: If could time-travel, would you go to the past or the future?
A: I would go to the past, when life was more slow-paced. These days, it feels like we’re chasing our lives to get to the end. I miss the simpler, slower times.

  • The Advantages of an Earthquake Safety Valve

    CONCORD — Due to high levels of seismic activity, earthquake safety is no small matter in the Bay Area. If you’re a homeowner, this means ensuring your home is structurally reinforced with supplementary measures like bolting and bracing. It’s also a good idea to have a family exit strategy laid out in advance. However, there are additional ways to augment earthquake safety for your home and family.

    One worthwhile measure is installing an earthquake safety valve onto your home’s gas line. When a major earthquake occurs, a home’s gas supply can become damaged, which can cause a leak that leads to fires or explosions. An earthquake safety valve guards against such catastrophes by sensing substantial seismic shifts and subsequently shutting off gas service to the home.

    Earthquake safety valves aren’t very expensive to install, but they do vary in quality, so it’s important to do your research and invest in a good product. Cheaper valves are more liable to be triggered accidently, which means you could shut off gas to your home if you bump against your valve while taking out the garbage. Worse still, cheap valves aren’t easy to reset—typically, it has to be done by a professional plumber, which results in an expensive service call.

    In contrast, high-quality earthquake safety valves are more precise in their sensitivity, so they’re less likely to be triggered accidently. Additionally, high-quality models are equipped with easy reset buttons, with no need for professional assistance. So, while a high-quality earthquake safety valve may be more expensive at first, it’s a more economical choice in the long run.
