California Water Heater Code Requirements: Straps, Drip Legs, T&P Piping and More
A water heater install that skips code parts can fail inspection, void warranties and put your family at risk. Here is what California requires.

Key takeaways
- California requires seismic strapping on water heaters.
- Gas units need a sediment trap (drip leg) and an accessible shut-off.
- T&P discharge piping must run to an approved location.
Every HOTCO installation includes the safety parts required by California code. Here is what each one does and why it matters.
Seismic straps
Two straps secure the water heater to the wall so it cannot tip over, break the gas line or flood the home in an earthquake.
Gas drip leg and shut-off valve
The drip leg catches debris and moisture before they reach the gas control. The shut-off valve lets you or a technician cut gas instantly.
T&P valve discharge piping
The temperature and pressure relief valve is the tank's last line of defense. Its discharge pipe must be the correct material and run to an approved location.
Dual-layer gas connectors
Flexible gas connectors with protective coating resist corrosion and damage better than older connectors.
Venting
Properly sized and sealed venting carries exhaust gases safely outside and prevents carbon monoxide backdrafting.
