Recommended Customer Reviews

Very professional and great customer service! Had a rusted water line that was leaking, saturating my front lawn. Did the work and replaced the pipe. 5 stars for taking the extra steps of showing me the old pipe and even bought more sod to replace the grass that was dug up! Thanks!

Dennis is knowledgeable and friendly. He did a fantastic job changing the garbage disposal. He took the time to explain everything after he's done installing the new garbage disposal. I highly recommend Tri-Valley Plumbing and will definitely contact them again if we need plumbing service.

Dennis is the first person in years who could fix the air hammer stuck in the pipes of my mom's back yard! We used to turn on the sprinklers and the entire house would shake. After Dennis took a look at the propertry, all of our pipes, etc. he knew exactly what he needed to do, fixed it, and no more air hammer!! He is AMAZING.
He also found a leak under a toilet that came up in an inspection report and fixed it. He is very professional, his staff is very professional and I wouldn't use anyone else. Next time you have anything going on with your pipes, call Dennis!! He is the best!

Please note right up front: DENNIS DILSAVER is the ORIGINAL, Tri-Valley Plumbing and has been established in the tri-valley for some years. I didn't realize this until I started calling around locally to find some specious companies not representing who they were truthfully and their longevity in the valley. It MATTERS to me to support local businesses in San Ramon seriously. Dennis can be proud of his hometown qualities of friendliness, excellent phone customer service and work ethic...all a real rarity it would seem these days. He came out right on time and helped me solve my plumbing problem with a toilet in a most professional if not competent manner. I NOW, know where to turn, where to go for assistance in the future. I was giving up all hope of finding a good service after many calls around this weekend...Well now I KNOW whose conscientious and cares...It's Dennis Dilsaver. He can certainly count on me for future business!!!!

Dennis has been my plumber on a lot of jobs in the past 17 years and has always been into what new out there and what things people want in the plumbing world.
If you need a plumber Dennis is the guy to call
Thanks
Dennis

As luck would have it our water heater burst on Thanksgiving morning. After getting a ridiculous price quote Friday morning, we contacted Tri-Valley Plumbing. Dennis said he'd try to get out later in the afternoon. Turned out the supplier was closing early so he picked up a water heater for us and came out earlier than anticipated to install it. Great service! And very reasonable priced. Definitely someone I'll be contacting and recommending from now on.

Highly recommend Tri-Valley Plumbing(Dennis). Called and got an appointment same day. He fixed all the issues I had from leaky shower to descaling the tankless water heater. He is very professional and efficient. I will definitely recommend Dennis to all my real estate clients and friends.

I've used Tri-Valley Plumbing services for years and have always known them to fix whatever problem I have without over charging me or trying to sell me some product that I don't want, like most other plumbers do.
Just good, honest work. Worth giving them a try when you need plumbing help!

We contacted Dennis based on Yelp recommendations. He recommended a great contractor and then did all the plumbing for the Master Bathroom renovation that was just completed. We could not have been happier with the result. Dennis is thorough, professional and wonderfully easy to work with. I wanted everything perfect and he had no problem accommodating me. Great experience.

I haven't used their services, but I think they deserve a good review. These guys are great.
I had a bathroom remodel done by a contractor that left a leaking pipe (I tried to find him on yelp to leave a bad review, but apparently he is not here...). He could not find the leak.
I called Tri Valley and they answered the phone immediately. They were busy in another site, but would stop by that afternoon.
Unfortunately, I called it off because I found the leak and fixed it myself.
I would definitely call them again in the future if I need.
