"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.

"Our sewer main busted and Oak Plumbing’s master plumbers Matt & Mike did a great job at digging down over 7ft to replace the broken section and also upgraded my single sewer main clean out which was nearly rusted through to a dual solid ABS clean out. And also I would like to add that Nate also did a great job at identifying our problem! Thanks guys! You’re AWESOME!"

"You would be very glad you called them instead of these other major plumbing companies. They took so much worrying off me and my family mind. They did not try to take advantage of the situations due to its emergency status like some company does. They come highly recommended by us."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

Affordable Plumbers questions, answered by experts

Seismic bracing for water heaters is highly sensitive to errors, as California law strictly requires double-strapping to prevent dangerous gas and water line failures during earthquakes. Improper slope on sewer lateral connections guarantees chronic blockages and eventual backflow. Furthermore, incorrect joint sealing on supply lines accelerates mineral deposit buildup from Napa's hard water, causing premature leaks. Always hire a licensed professional to ensure proper installation.

Helpful?

Functional plumbing changes, like relocating drain lines, require municipal permits and rough-in inspections before you close the walls. Cosmetic updates, such as swapping a faucet, bypass these requirements. However, replacing a sink in older Napa homes exposes corroded stop valves and deteriorating drain lines, turning a simple cosmetic upgrade into a mandatory functional repair. California water efficiency standards also restrict your fixture choices.

Helpful?

Homeowners consistently underestimate permit lead times, which add weeks to a project start date. In Napa, replacing a water heater involves complex venting modifications and seismic strapping to meet state energy standards. You must also anticipate seasonal scheduling constraints. During the fall wine harvest season, contractor availability tightens significantly, making it difficult to book a local professional for your plumbing needs.

Helpful?

Brown or rust-colored water from faucets indicates advanced pipe corrosion approaching total failure. Multiple slow drains throughout your house signal a compromised sewer lateral damaged by shifting clay soils. In Napa homes with raised foundations, white mineral deposits on crawl space walls point to chronic moisture intrusion from hidden supply leaks. Treat any new drips after CA earthquakes as serious stress damage.

Helpful?

When planning plumbing projects in Napa, hidden expenses arise from local permit requirements and separate sanitation district connection fees. In older neighborhoods, opening walls reveals corroded galvanized steel or cast iron pipes that demand immediate replacement. Additionally, homes in flood zones near the river require moisture damage remediation before any new installation proceeds. Always account for hard water scale buildup requiring extra pipe remediation.
