Water Heater Services in San Francisco

Pressure Management First

SF’s 130+ PSI water pressure destroys water heater components faster than any other city in the Bay Area. Every water heater project we do in SF includes a pressure test. If your home is above 80 PSI, we install a pressure-reducing valve before any new equipment goes in.

• Pressure test included on every SF water heater job
• PRV and expansion tank installed when pressure exceeds 80 PSI
• Expansion tank required by code on all SF closed systems
• High pressure kills water heater seals, connections, and safety components

Safe: 65 PSI · What we see in SF: 130–140 PSI

What type of water heater is most popular in SF?

Tankless gas water heaters are most common in Victorian and Edwardian homes — wall-mounted units from Navien and Rinnai fit tight utility closets and deliver endless hot water. In the Sunset and Richmond where garages are common, heat pump water heaters are increasingly popular.

Do I need a permit to replace my water heater in SF?

Yes. SF DBI requires permits for all water heater replacements. We manage the entire process including seismic strapping and the required mechanical inspection.

Why does my water heater keep failing?

Most premature water heater failures in SF relate to unchecked high water pressure — it destroys seals, connections, and safety components faster than normal. We test pressure on every service call and install a PRV if needed. Annual maintenance catches these issues before they cause failures.
