Tri-Valley Plumbing

They do not return phone calls at all. I gave up and had to hire another plumber. It's too bad because it's just a matter of getting back to your good customers in a timely manner and they just can't do it.

I woke up to water running out of my garage with a pool of water at the base of my hot water heater & furnace. One call and I had a technician scheduled within 2hrs. Victor arrived on time and ready to work. He was thorough and explained everything in layman's terms before he did any work to set expectations. He was quick, clean, transparent in pricing and reasonably priced for on demand plumbing needs. I would invite Victor back into my home -I stuck his business card to my hot water heater for future reference.

Dennis remains the top reason I always find my contractors on Yelp - he just finished a laundry list of plumbing tasks at my house, did fine work, and charged a very competitive rate. He always goes above and beyond -- this time, he painted our exposed PVC pipes to bring them up to code, and they look better, too. I think this was Dennis's fourth visit to our house in three years (he helped us during a large remodel), and I'm just as impressed as ever. Great work, Dennis!

Dennis came out to my house to check out my water heater in my garage that had been leaking for about three days. The day before, Ben Franklin came out and gave me a $3,000.00 estimate to fix the problem by replacing the water heater in question. Dennis used his expertise to quickly diagnose the problem as a leak, not from the water heater, but from the hot water intake line. He removed the line, cleaned the connection, and reconnected the intake line with plumbers tape on the threads. Not only has there been absolutely no leak for the past two weeks, but I did not have to replace my water heater as the other company was so fast to suggest. Dennis is the best in my opinion. I would hire him in a second to do any plumbing work I need. Thanks Dennis! You are the best! Frank

Dennis has done a couple of jobs for me - including a very tough repair in my downstairs toilet where a tiny leak in the waste pipe from the upstairs bathroom had caused some major water damage. Like all jobs, one problem leads to another, but Dennis took care of everything - and hooked me up with a new water heater as mine was on its last legs and still got the job done in a day. He also hooked me up with a construction guy to fix my shear wall and a dry wall guy to patch up at the end. I heartily recommend Dennis - he gets the job done, to a high standard and is very reasonable.

Called this service after my neighbor across the street recommend Dennis. Got an answering machine and left them a msg requesting a call back. It's now the following day and still no call back. Ended up with a different plumbing company to work with so they need not call me back anymore. I had heard good things from my neighbor but I can't say the same about his promptness in call backs.

Didn't think the other people leaving reviews about not returning calls were referring to this Tri-Valley company until I called their number (925) 556-5511 yesterday (Monday) at around 10:20am and had the same experience.

I am new to the area and needed a couple of simple plumbing tasks completed before moving in. My Realtor recommended Tri Valley. I called 3 times and the never called back.

Dennis is very responsive, came on time, assessed our plumbing problems and worked to resolve them. While working on a different problem he and his assistant, Giovanni, found a leak in the toilet under the house. The cost was reasonable. He and Giovanni are respectful of your home. Trina was helpful in scheduling appointments. He offered to talk to my contractor to resolve the final plumbing issue that requires a wall to be opened to resolve. I am very happy with the communication and service, and will call Dennis again if needed.

Dennis did a great job on a tricky plumbing problem. Our shower fixture is old and the parts are not easy to locate. He worked with a local supplier, came out a number of times to try and find the perfect fit.

He was great to work with, fast, very reasonably priced, and found the exact parts needed to get us back in working order.

We will definitely use Tri Valley Plumbing again!

Dennis came out to replace the faucets in 2 of my bathrooms. He was friendly, on time, and did the job. What was the problem? I guess the old faucets were hard to get off and Dennis had a hard time. He was sweating, struggling to fit under the sink, (I was worried he'd have a heart attack) and I don't think he was real happy but he finished the job. However, soon after, when the sink started to show rust rings around the faucet handles I called him back and he never returned my call. I had to turn off the water to the faucet and call a different plumber. I wouldn't use them again.
