Recommended Customer Reviews

Octavia and his assistant showed up promptly on time. He was not trying to influence one way or other. He didn't coerce me to buy a new water heater or bias me into fixing the current one. He gave pros and cons of both the options to allow me decide. Sounded like a very fair guy.
His quotes for replacement with a new heater as well as fixing just the old one were among the best and reasonable. Non-nonsense, no-rip off guy.

I can't believe these crooks have more than 1 star. I had a leak in my kitchen and called superior plumbing.
They had great reviews but I couldn't believe it. They charged me a massage amount of money and didn't fix the issue.
When I called to get them to come back they told me they would charge to fix their mistake. This was an easy fix and the have seriously ruined our plumbing.
I'm exhausted by their customer service and each time I call I have to explain this over and over again. Tip: DO NOT USE THEM!

Just found out that the main line to our house is cracked right where they did work... Explains the $800 water bill...right with the shoddy work done that is now costed us over $2,000 and counting.
San Jose Water Company on their way out to shut off the line from the street so the house doesn't flood. again we'll have to go likely the whole day without water, re-dig and re-do the work they did wrong in the first place after causing the entire mess (when nothing was wrong in the first place)
I would ask them to make it right but after all the $ and headache with Inferior Plumbing, I rather just pay out of pocket to a company that will actually fix issues they cause.

Came through our home warranty to fix some minor leaks in kitchen. On the way out, plumber checked main line pressure and said it was way too high and that the regulator must be broken. Ok, so home warranty covers that, right? Wrong...Start of the nightmare.
As plumber is working to replace main line (no water supply to the house but should be a quick fix), the guy cracks the pipe below so he ends up having to dig 3 plus ft near foundation.
Surprise #1: home warranty doesn't cover excavation...but shouldn't the plumbing company cover this since they cracked the pipe which required them to excavate in the first place??
Finally after two days with no water, pressure regulator is replaced.
The next morning the irrigation system starts spraying/leaking from a back flow preventer. We call superior plumbing are we're told this is not related, hahahahhahaha!!!!
What a coincidence - 9 months in the home without any issues, and the day after they finish working on the main line issue/excavation extravaganza, we have another plumbing issue in the same location.
But the worst part besides costing us $1200 and our home warranty about the same amount? The fact that they insisted the irrigation system was faulty, when the real issue was that they did a messy job and didn't flush out the main line system, causing debris to get caught into and break the seal of the back flow preventer.
They replaced the old leaking back flow preventer and charged us a ton. Then 1 week later, when the same exact thing happened again (another leak just like what happened with the old valve), it was miraculously fixed by simply removing a tiny pebble that was breaking the seal. One of their own guys found this to be the ""true"" cause.
In other words, it was a 5 minute fix; not another $1,000+ job if they actually knew what to check.
Since they never properly flushed the lines, I've fixed it myself two more times in the last 4 months by removing small debris that was caused by their messy work done on the initial main line.
These are the facts.
Just make sure you educate yourself before these guys come by, cause you may end up costing yourself a lot more than is necessary.

Knowledgeable and responsive. Needed to change the appointment date and they worked with me, no hassle. They communicated clearly, showed up when they said they would and worked with our home owner's insurance to replace our hot water heater in the same day. They even gave us a deal since we are a repeat customer. They clearly care about doing a good job and making their customers happy.

Call Octavio for help. He come in 15 mins & did an excellent job. He even did all the cleanup for me. Definitely highly recommend.

Superb service and willingness to solve my leaking washing machine problem. Andy is a champ with a great attitude. I will definitely call these guys again if I ever have plumbing problems.

Andy did a great job for us back in October. I appreciated the attention, communication and help he provided. In addition, they were flexible and willing to work with us and AHS. I appreciate the work done.

We had a leak at the hose bib where our main water line entered the house. There are two pipes, one that is the water main, and another one (that was leaking) that services the old irrigation (we just bought the house, so we weren't sure which was which). Each has its own shut off valve above ground.
Superior Plumbing sent out a guy on short notice (bonus point!), but he spent several hours trying to figure out what to do, and eventually called his boss who tried to convince us in person that they would have to replace the entire water main, break up the driveway and sidewalk, and it would cost $8,000. He also tried to convince us that we'd *have* to replace our water heater and piping to it - (what?!)
Another plumber looked at it for 3 minutes, turned the shut-off valve to the irrigation branch of the leaking pipe, and our problem was fixed. The main line does not leak - and he was blown away that the previous (Superior) plumbers missed such an obvious fact.
Edit: Octavio called to apologize for his mistake. He was very nice, and I appreciated it. However, it could have been an $8,000 mistake, so I feel the review must stay in place.

Took care of my water heater issue, thanks to Andy!
