Recommended Customer Reviews

This company and PHIL GRUBER the owner of the establishment is a joke. I'm a plumbing contractor in the peninsula and he was sent over by state water heater due to a recall on the heater and state water heater would not ship the the parts for the repair due to the recall. So they dispatched PHIL GRUBER from Gruber plumbing because he is contracted with state heaters. These customers have spent thousands of dollars with me in the past and for him to remove a circulating pump from a union and charge $350 for is just ridiculous. Customer returned to notify him that they were willing to pay the $350 he simply refused because he was simply lazy to go back to his truck and get his tools. He told the customer to make another appointment to fix the heater after they have been out of hot water for 2 weeks. Unfortunately she called me to order the part which she was willing to pay for from her own pocket. I simply called state water heater and filed a complaint and had the warranty dept send me the burner assembly and I simply went back and installed the burner assembly without removing the circulating pump. This company is so horrible and I felt for the customer that I felt obligated to write a review on this business. STAY AWAY FROM HIM AND HIS BUSINESS!

Writing a review on Phil Gruber is really a waste of time since I'm sure he does not care what people think of his service. He came to look at a Tagaki unit that was not producing hot water. After 25 minutes he announced that this was a problem for PG&E and then proceeded to charge me $408 for service. And on top of it, he was rude. Don't use
him if you don't want to get ripped off.

This post is over a month over due. During one of the heavy rain/wind storm last month, our water heater would not heat up. We were forced to take cold showers that day as we could not get a plubmer to come in on such short notice. On one of our last calls, we called Gruber Plumbing and talked to Phil. He too, could not come on the same day to see us due to his schedule, but he was kind enough to troubleshoot the problem. Phil knew exactly what was wrong, our burner was not turning on due to a problem caused by the heavy winds. We were afraid of turning off the very dim pilot at the time for fear of not being able to ignite it again. He instructed for us turn off the pilot for at least 10 to 15 min and then restarting it. It worked and I was thankful to be able to take a hot shower on that very cold day
Thank you Phil, we will be calling you with any future plumbing problems.

I wished I could give them NEGATIVE STARS (-VE). Have water heater problem, Phil came and compliant that he can't fix it because the cabinet area which we were willing to take down the cabinets and still he found other excuses to not help us out. He did NOT fix it and probably broke it even more and just took off. We called Janice, the scheduler, sucked. She can't do anything, there is no customer service at all. Multiple people in my family called them and they kept switching up the stories on what the issue was and it is still unclear what the issue was. At first, he said it was just fine and then right before he RAN out he ""happened to mention"" that there was no hot water leaving us with no real explanation. We called back and he said there was no way for him to fix it because of ""x,y,z"" but in reality it seemed as though he did not even know what he was doing to begin with. They were really rude and immature and unprofessional in their way of business. Find another company.

We bought a new water heater and the pilot light would not stay lit. Called the mfg and they called Gruber Plumbing to come out to do the warranty service. At first Phil the owner came off as a bit of an jerk, but when he showed up he was fast and efficient. He replaced the thermocouple and the pilot light stayed lit and we have hot water!

Electric Water Heater installed, old one was leaking and couldn't be repaired. Everything was done right and in a timely manner.

My water heater manufacturer referred me to Gruber Plumber for an issue I had with my water heater. I talked to Gruber at 8:30am and he was able to come in on the same day. He was able to identify my problem right away and fixed my problem within 20-30 minutes. Really happy that the manufacturer referred Gruber Plumbing!

I tried to call to get an estimate and used the phone number listed on yelp and in his voicemail. But as soon as he answered the phone he claimed that my water heater was not emergency. Like I don't have to work and can just sit around. Our water heater has been broken for two days. He quote me on $390 to come out for a diagnostic. I ask if the whirlpool warranty would cover he said ""uh huh yeah sure they didn't tell u..."". Click

Phil Gruber is like a medical doctor when it comes to plumbing. Seriously. He just used a stethoscope to solve an annoying noise-related problem for our condo building's hot water heater. If you want a thinking man's scientific approach to plumbing troubleshooting, Phil Gruber is your doctor... er... plumber.

Gruber Plumbing arrived the same day to troubleshoot my water heater and left causing more damage than good. Admittedly he did get a warranty part on order however immediately after he left ALL OF MY PLUMBING FIXTURES FAILED which left me without water pressure or hot water in all of my fixtures. I called Gruber the next day in hopes he could come take a look and he confirmed he would be over at 1230 to review. Well, 1230 turned into 530 and when Gruber finally showed up he took one look, admitted something drastic had changed in the house, but without touching anything to repair or assess, he insisted I commit to paying his HOURLY FEE OF $350/HR. Once it was clear he was out for his money grab I asked him to leave and it was at this point he caused a scene in front of my wife and young son. I have not provided many Yelp reviews in the past however this experience has left me without a working sink or shower over the holidays and I felt compelled to warn future customers about this terrible experience. Think twice before using Gruber, he may be responsive, but that's because he will charge $350/hr, in some cases just
to fix his screw ups!
