He explained everything every set of the way. An excellent plumber. I plan to use him for any future projects will need."

"Jesus was awesome - not only was he the first to respond to my inquiry, he fit me in quickly after a weekend and did the best job of any plumber I have ever had service my condo. Not all plumbers do a thorough or ideal set up and Jesus corrected what was leaking and fixed prior issues. Personable, professional, and reasonably priced, I am definitely hiring him again for any future plumbing work!"

"The owner, Mike, came to inspect the problem (DIY mess left by me. A half threaded part of shower arm stuck behind) and then proposed a solution which he trusts his job team lead, Manuel, could improvise as needed to avoid cutting through tile walls to minimize damages (and implied later headache and hidden cost). Which all other bidders all included cutting the tile wall without patch-up post job done. Mike was a very good negotiator and flexible at coming to a bid price I cannot not wait and compare. Otherwise, I could lose the reasonable offer. Mike is like an openbook. After job bid approved, he immediately schedule the work for next day right at the table. Manuel led a team of 4 for my project. Manuel is a nice guy, very approachable and would explain any questions I had. Nicely getting job done. At the end, the staff even vacuumed the mess and no trash left behind. I would definitely invite Mike/Manuel team back should I need another new plumbing job to be taken care of."

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

"Our old water heater was about 20 years old.  It did not pass an energy audit for CA State rebates so we had to replace it or forfeit the rest of the work we wanted done under the State's energy improvements rebate program, Auditor estimated $1700 for replacement,  
After calling 7+ plumbers, we chose Water Heaters Masters because:
 + they would pull a permit as required by the State rebate program (several would not)
 + their price point (they were one of the two lowest), 
 + their familiarity with all the options we wanted to consider (many installed a single maker or were unfamiliar with the most energy efficient models), and 
 + their immediate availability (the same day).
Alex (manager) and Anthony (technician) were very professional in setting up and installing the water heater.  Everything, including potential contingencies, was priced in the estimate by Water Heaters Masters.  When the City Inspector wanted the overflows (pan and water heater) run to outside of the house, Water Heaters Masters kept to their estimate despite the long run of copper and PVC needed, and the trickiness of running those lines around the adjacent new HVAC and its ducting in the crawlspace.  
We were so impressed that we wish they did more plumbing work.

"After talking to Jaime of SWAGS, I was made aware that it was not his company who did the plumbing work in my house, but anothe company. My apologies. Jaime was also kind enough to tell me that his company makes sure to be on the appointed time or if not, that their customers are reasonably informed of any delay. His company would have been my first choice since he told me he tried contacting me 3 times and did not get any call back from me. It must have been the day or days when I was having problems with the phone service. If only for his effort to reach out and that he was nice enough despite the mistake speaks greatly of professionalism I will definitely give his company a call the next time the need arises."

"I had an outstanding experience with Plumbing & Rooter Service. From start to finish, their team was punctual, professional, and highly efficient. The quality of their work was exceptional, and it was clear that they take great pride in delivering top-tier service. Their pricing was very fair and reasonable, especially considering the speed and precision with which the job was completed. Everything was handled smoothly, and they exceeded all of my expectations. I highly recommend Plumbing & Rooter Service to anyone in need of reliable, high-quality plumbing services. I will certainly be using them again for any future projects."

"Wilmar Plumbing was very responsive and empathetic towards my situation. They had to fix a problem caused by the previous plumber who installed my shower/tub drain incorrectly. I couldn't shower due to the leak. They treated my case like the emergency it was and Wilmar and his team showed up first thing. They fixed it diligently. They were so good, I hired them to install new bathroom sinks. These guys are great!"

Plumbing questions, answered by experts

Upgrading your plumbing directly eliminates health hazards like lead exposure in older homes. Replacing corroded pipes restores proper water pressure and prevents hidden moisture damage inside your walls. By addressing root intrusions in your sewer lateral, you prevent foul odors and dangerous sewage backups. These updates make your Sunnyvale home much safer, more comfortable, and highly resilient against strict local water restrictions.

Helpful?

Always schedule a final city inspection to close out your permits properly. After finishing plumbing work on supply lines, flush your cold water taps for several minutes to clear out any trapped sediment. You must also verify that all new fixtures meet CA water efficiency standards. Keep all your inspection records and contractor documents safe, as buyers demand them during future home sales.

Helpful?

Account for active seismic zones by installing flexible gas line connectors and automatic shut-off valves to protect your property during earthquakes. Sunnyvale features expansive clay soils that shift and crack underground sewer laterals, making camera inspections essential. You must also select high-efficiency fixtures to comply with local drought regulations. Hire a licensed professional to handle all permitting and ensure your plumbing meets current codes.

Helpful?

Watch for sudden increases in your tiered water bills, which point to hidden leaks. In many older Sunnyvale homes, discolored water indicates failing galvanized pipes that require immediate replacement. You should also check for white mineral scale buildup around fixtures caused by hard water. Schedule plumbing updates if your home has original pipes to prevent severe damage and ensure a safe water supply.

Helpful?

Install anti-scald mixing valves in your showers to protect children from sudden hot water burns. You must also add backflow preventers to your outdoor irrigation systems to keep harmful soil bacteria out of your drinking water. Cap all exposed outdoor pipes so pets cannot chew on them. Upgrading to lever-style faucets makes everyday plumbing use much safer and easier for little hands across California.
