Tri-Valley Plumbing

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.

Dennis and Giovani were great. He came out to give an estimate and ended up staying to do the work. He explained everything, tore up only as much stucco as he needed to, and cleaned up everything. He was friendly and knew his trade. I would use him again (hopefully I won't need to) and I would recommend him.

We used Tri-Valley Plumbing for our broken garbage disposal. I would definitely use them again!

Pros:
-quick quote over the phone - simple
-same day service
-on time
-polite and got the job done quickly
-super nice woman on the phone to set up appt and pay

Cons:
-didn't look professional... shorts and a baggie, sweated through t-shirt
-had to wait for a call in order to pay over the phone because he couldn't take my payment in person

We had the opportunity to use Tri-Valley Plumbing again since my last review. Dennis is professional, courteous, clean and gets the job done the first time. Having worked with so many flaky contractors in the past , it's a relief to find one that you can count on. Plus his prices are very reasonable. I highly recommend him for all of your plumbing needs.

Had the water main break near the front of our home and Dennis and his apprentice, Giovanni did did an outstanding job of quickly and efficiently fixing the problem. Would highly recommend Dennis and his team for any plumbing issues you may have.

Dennis and Giovani were a pleasure to deal with as they re installed our dishwasher and put in a cut-off valve to the appliance. Dennis initially came out to help us when we came home to a dishwasher that had been linking while we were on vacation. he kindly sourced the issue and repaired the leak at no charge. Just asked to do the install and the valve when we had floors repaired. Dennis got rid of the crappy hoses that came with the dishwasher and replaced them with heavier and more durable ones. He explained that the originals become to brittle and are not worth the time to install originally. They were not in a rush and took their time, checking and testing everything so we knew that our new floors would be safe.

Dennis and his apprentice Giovani were very friendly and professional and are highly recommended by us.

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!!!!
