Because of all the great reviews for Knockout, we added them to our list of vendors to get quotes for a repipe of our duplex rental property. The pricing was very fair for all the work items they were going to complete.

This team of multiple people arrived and were busy working the project. I could tell they had done these type of projects multiple times as their work was efficient and clean. I was very impressed.

For the most part, they kept me informed of the progress, telling me when and what they would be doing next. I was very happy with their service and will continue using them for future plumbing projects.

House built in early 1970's needed transition from lead pipes to copper ones. Knockout (Martin & Edgar and their 5-man crew) exceeded our expectations, including interfacing with the City on permit and inspections. 17 days from bid to completion (approval of final inspection). Careful workmanship included protective covering on the floor and polyethylene taped to walls to control dust.

I needed a garbage disposal installed, I made an appointment with
Knockout plumbing and the quote was $826.00. I declined and called
another plumber. They quoted me a price of $283.00 including tax
and installation.
I like to support small companies but Knockout bid was simply
outrageous.

I am very happy with the whole house re-pipe work done by Edgar and his team. No leak post the re-pipe.

The re-pipe was done in a day and then patching. We also got city permit approved for this project.

Staff is friendly and Edgar and his team is very professional.

I would highly recommend knockout plumbing for any plumbing work.

Also the clean up job post re pipe was also very clean. Patching was done very professionally as well.

I have a 60 year old 4-plex rental building in San Jose. The water pipes are original galvanized iron pipes and they started affecting water quality for my tenants in the last 12 month or so. After getting estimates from 3 licensed plumbing companies, I hired Knockout Plumbing and Repipe to do the project. All 3 companies have extensive experience in repiping project. They all have good customer reviews on both Google and Yelp. Knockout gave me some discount. They started the job on May7th and finished the job on May 11th. Only in the first two days, they needed to shut off water for about 10 hours during the day. They use top quality parts. Their young plumbers are well-trained and professional. After the entire plumbing system was replaced, they did extensive test to make sure no water pipe leaks. They took care of San Jose City inspection well. The two inspections were scheduled timely and went through smoothly. The owner, Edgar, is professional and easy to work with. His younger brother Juan and his staff member Kevin also left me with very good impression. I highly recommend this company to anyone who has similar needs.

Great work and service. I had a pretty big job done. They replaced the main water pipe out to the street. It was completed promptly and they kept me informed during the down time (waiting for the city to approve the permit.)

There was a minor issue with the reattachment of the sprinkler system. But when I advised them of the issue, it was handled the same day. I would use them again. They are pleasant to work with.

Very impressed with the service. Francesco is a knowledgeable plumber and figured out the issue with my dishwasher quickly. He was patient and talked me through what could be the cause for the blockage. Highly recommend the prompt service. Thank you!

Melissa H.

Very responsive and did a simple repair quickly and reasonably priced. I will use them again next time.

Francisco did a fantastic job to unclog our kitchen sink. He clearly explained the problems and options to fix them upfront, did a thorough job to snake the pipe, and cleaned up everything at the end. The cost was reasonable and I am satisfied with the result.
