Recommended Customer Reviews

We needed an emergency 2"" domestic water line repaired in Hayward. Our regular service company was unable to respond with 48 hours on site, so we called Joe to see if we could get some help. He had a team there within two hours ready to rock and roll. Lamberto was the crew lead and immediately gave the open option of being able to start immediately hand digging once asphalt removed or waiting for the utilities to be marked if we preferred. I somewhat knew the layout of the parking area utilities and only had one gas line to be careful of, so I called my office and got our PM's approval to start without delay. Within two hours, they had found not only the line but the breach without waiting for any locators which to me shows exceptional skill on task for traditional plumbing. By 4pm same day the building was restored, lines flushed and trench safely back filled and covered to await paving repair.
Excellent service, professional work and timely..... timely was quite important here as we had a food service client down due to the line break.
Lamberto, Fernando and Antonio great job.

I had a good experience working with Pacific plumbing. I did Gas line trenching and sewer line replacement with them, which needed a lot of crews and time. Since they are a big company which has a lot of experience, I didn't have to worry about anything while I was working with them. They'd done their job properly and worked so professionally.

Pacific Plumbing recently came to our rescue in Livermore. A leak that required tracking down its source in a very odd plce, working me into a very short window and doing it for a more than reasonable. I would recommend Ron and his crew anytime.

I arrived home from a week long business trip to a house without hot water. I called on Friday afternoon, and Jose came out within 2 hours. He quoted me an all-in price of $2900 for the water heater and I assumed he was trying to rip me off. Then he explained that I have a 75 gallon power vent water heater and invited me to shop around and call him if I change my mind. No charge for the inspection and advice.
I called Home Depot, who don't carry this type of heater. Then I called Lowe's. Their model was $3,150 plus tax, installation and old tank removal, $3,800. Oh, and it would take 2 weeks to order the replacement. I called Affordable Water Heaters and Plumbing, who wanted to charge $4,990. Water Heaters Only would only say the cost would be between $3000-$3600, depending upon the installation expense and cost of new code compliance rules. They could install it on Tuesday.
I called Joe back. He said that he could get the new water heater Monday morning and have it installed Monday afternoon. He was also very flexible to work with my insurance company, because he wasn't on their list of plumbers in my area.
All in all, I'm satisfied with Pacific Plumbing for being reliable, friendly and responsive. I'd recommend them to any of my friends.

Referred by leasing office. Appt for 9:00 am.; they called to change to 8:00 am.
Came in to work an hr early. 8:30 I called..running late. 9:00 I called sorry almost
there. No courtesy call saying they were late....cancelled the appt.

Will never use them again. I had a serious pipe break in my house. I called at 9:50PM and their message service company answered and took a message. They never called back so I called again at 8:30 the next morning. The person told me they had someone available and he would be heading over. I explained the details of the issue and she said she would be sure to relay the details to the plumber. At 10:45 I called again as they had not arrived. I was told he was running late but would be there between noon and 2. At 2 I called again and was told he was still stuck but would be at my house by 4. At 4 I called again and, while she apologized profusely, she assured me he would be at my house by 5:30 and I reconfirmed he understood the details. At 5:45 I called again and got their message service. Finally, at 6:15 he showed up. He walked in, looked at the broken pipe and said, ""I don't have any material for this so we'll have to reschedule for tomorrow"". I kicked him out of my house and will never call them again. Horrible service.. cost me an entire day of work and now my family will be without a bathroom for 2 full days.

Uh-oh..it was time to call the plumber..up late, running the washer, next thing you know it, toilet is over-flowing, whole hall way was wet.
I was actually referred to Pacific Plumbing, reached out to them and they dispatched a tech and he arrived in a timely manner. That right there was already a relief for me, he was able to snake, I requested for a camera to be ran from all of my drains just for my own comfort. The tech was very informative and provided lots of preventive maintenance tips, really spent his time, did not try and over sell me on any products or unnecessary services. I was made AWARE of what else they can offer but not forced or felt my back was against a wall.
All in all the job was done, the remainder of the hallway mess was working with a restoration company.
Thank You!

I have had nothing but good experience with Pacific Plumbing. They are very reliable. I own two complexes in the san jose area and they have been my contact for any type of plumbing issues. They always get to the root of the problem and tell you how it is. They find the problem and fix it. I have been dealing with this company for over 10 years and have recommended them to all my friends. I was reading a few of the yelps on here and am astonished at the lack of knowledge people have. My recommendation do some research on how plumbing works and then give a review. They are a great company with great prices. I highly recommend using them.

I wish I can give them 0 stars. Pacific Plumbing came to our house and attached our volume controls and thermostatic mixer as well as the bathroom toilet and kitchen faucet. It took them more than two tries to put the volume controls straight. (There were gaps on the top or bottom, or on the right or left, even with the rubber washer/gasket.). Then they overtightened and cracked the tile.
Had to get a tile man to replace our newly installed tile.
They did not put the Hansgrohe logo at the 12 o'clock position for the thermostatic mixer. The volume control knobs were upside down. It took them few tries to fix them and I finally got them fixed today.
They did not even ask for a preferred temperature to set for the thermostatic valve. The safety button to prevent scalding was not installed properly and the safety was not working at all. It wasn't until today that they finally set the temperatures but since they left without briefing me what they did, I can only assume they used a thermometer and set the temperature correctly.
I wasn't even there at the jobsite all the time when the plumbers were working and my general contractor is the one who called them but for whatever reason, I got a invoice in my mailbox...yes, when the job has not been completed yet! (and it should go to the general contractor) It is today that they finally seemed to have finished installing things properly although I haven't had a chance to check out everything yet. I was only able to check visibly as I didn't even know that they had already left by the time I got there.
1)The invoice needs to go to Salas Construction as they used Pacific Plumbing for a job they were initially supposed to do. I should be paying Salas Construction and Pacific Plumbing should be paid through Salas Construction. I didn't call Pacific Plumbing and it's Salas Construction dealing with them.
2) The toilet was not connected properly. I bought one of those toilet with wireless remote, etc..(so not your typical toilet here in the U.S.) . The wire was just hanging outside the toilet, the battery compartment was not installed, the toiled seat was not aligned properly. The brand new toilet cover lid is all scratched up.
3) $400 for a drill bit? Where is the drill bit? If they are charging us, should they leave that behind on site?
4) Pacific Plumbing is charging per hours for a job they should not be charging. They sent plumbers who couldn't follow simple instructions and couldn't install things properly(thermostatic shower system, toilet, etc). Hence it took several more trips/people for Pacific Plumbing to fix the incorrect installation. ..and I'm being charged for that? I am really curious to ask the California License Board for the way they run business.
They have delayed the remodeling project big time. They billed me before even finishing the project. Even worse, it said they will charge me extra $$$ if I dont pay by due date (July 2nd) when I got the mail on July 5th!
I'll be writing a review for my general contractor and he is the one who called and got this plumber. If it was me, I would have checked Yelp first, for sure!
I saw that some other reviewer put a link to the complaint board...I totally agree with that reviewer. I hope I get a copy of a revised invoice as the original invoice should go to Salas Construction, AND I would like to believe they sent that invoice incorrectly to me prematurely. I guess I'll find out very soon!!!
P.S.
Oh, by the way, they lost the instruction for the thermostatic mixer!
They also installed the shower valve through an opening of the tile and...they just put the cover plate to cover the hole! I can see lights coming through from the drywall from the next room. No caulking, nothing!!! Really? Are they kidding me...water will go through that loose cover plate right into the hole in the tile and into the dry wall...

Please do yourself a favor and stay away from these guys. I wish I would have read the reviews posted here before I had them over but glad I checked before I went any further.
We had Pacific out to clear a blocked sewer - entire house was backed up. They snaked it then it was fine. A month later it backed up again so we had the city out this time thinking that our side was clear from the work that Pacific did. The city said it was our side again.
We called Pacific again thinking it must be something major on our side if it backed up again so quickly. They suggested a technician with a camera should come out and video our entire system to identify exactly where the problem is. They described this service to include a video on DVD that we could watch that would clearly show the problem, an explanation from the technician and some kind of identification at ground level where we could find the problem if we needed to dig it up. This service cost $250.00.
They came out and did the job. I wasn't able to be home for the work so my neighbor stood in for me. He relayed what they told him, I saw the flag where they marked the problem's location and the technician explained to me over the phone what he found. It sounded pretty straight forward and I figured when I watched the video that would show me (as the tech explained) exactly what the problem was. He said the pipe would have to be dug up as it was dislodged from another pipe. He said he would have someone from the office call me to set up the next step including an estimate of the work.
I got home and watched the 6 minute video which was 75% under water and therefore useless to me. You can't see any pipe problems under water. In fact I couldn't see ANYTHING under water. I thought the guy would snake the drain and clear it before he spent $250.00 of my money creating a useless video for me.
So I figured, no big deal, I will simply let the company know what happened and have the technician explain to me over the phone or maybe drop by for 10 minutes to explain to me what is shown on the video. Maybe it takes the trained eye of a plumbing video technician to ID the problem - I'm a patient guy.
I call 3 times to explain what is happening. Twice the dispatcher apologizes for not responding to me and tells me the technician will call me right away and all three times I did not receive a call. In the meantime, my sewer is completely backed up and I have not even received a call about the ""next step and quote"".
If you are having similar problems with them and they are not responding I suggest you do as I am doing and lodge a complaint with the California department of consumer affairs. Here is a link for your use https://www2.cslb.ca.gov/OnlineServices/ConstructionComplaint/BeforeFilingComplaint.asp
If you are considering using them, I suggest you do not.
I hope this helps.
