"Edgar led the project . He and his team were timely, knowledgeable, trustworthy and conscientious. The most caring and thoughtful plumber I have ever worked with. I have an old house so future plumbing issues will arise. Aaron’s is the first and only call I will need to make."

"My dishwater was not working anymore and the error message showed it was a plumbing issue. Anthony from Mike Council Plumbing was my technician. He did a full check on both the pipes and the dishwater and was able to diagnose that it was the dishwasher not the plumbing. I really appreciated him taking the time to explain the issues in detail. If things break, I will ask to have him back on the job. Extremely professional and very continuous with all the Covid protocols. Great service!!!"

"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.

"What started as a simple toilet replacement encountered a couple curve balls because the age of the existing home. Wilmar Plumbing marched right through and solved the problems, even though they were not all plumbing related. And they did these "extras" at no additional cost! They arranged a date quickly, were responsive to my calls, arrived on time and cleaned up the mess in an quick and efficient manner. Wilmar Plumbing came in a large van that was fully equipped with parts, no running off to Home Depot. I already have another project in mind and won't hesitate to bring them back. Thank you Wilmar and team!"

"You will be so pleased that you chose The Tankless Guys to look after EVERYTHING and anything to do with plumbing in your home. Gert has been my go to professional for over 10 years for ALL my plumbing needs. He operates with the highest integrity. His top priority is to do what is in the best interests of his clients. Gert and Sergio installed my new water heater two years ago. Sergio stayed for much longer than he shouldâ ve after installation was complete. He took extra care to figure out how to program the timer for my existing hot water recirculator which was not part of the water heater job. He didnâ t have to stay, but thatâ s how Gert and Sergio are. True professionals willing to lend their expertise. Some plumbing companies out there send NOT very qualified plumbers to do the minimal and/or charge you a significant amount for unnecessary work. Gert is a straight shooter. He has saved me a ton of money to replace what needed to be replaced and NOT replacing what did not need to be replaced or fixed. He will tell you whatâ s the most economical and efficient and what you need to do to protect your home from future plumbing problems. If you want cut rate prices with NOT the most qualified plumbers, donâ t call The Tankless guys. If you are looking for a team who thoughtfully looks after your whole home and considers preventative measures that you might not have considered, Youâ ll be so happy you called the Tankless Guys. Remember you get what you pay for."

Plumbing FAQs, answered by experts

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.

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?

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?

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.
