What kinds of pipe fittings do you use?

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.

What materials and products do you use?

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.

Do I need a permit for my plumbing job?

Most replacement work is done with a permit. We’ll pull permits through the city or county for anything we replace or alter.

Can you perform real estate plumbing inspections?

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.

Can I trust your employees?

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.

Do you offer financing?

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.

Hamid Rod Tehrani: A Technical Advancement

By James Florence, Diamond Certified Resource Reporter

CONCORD — After eight years of working construction, Hamid 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 fo...
