Water heater bracing requirements in Los Gatos
The state of California has water heater bracing requirements for both gas and electric water heaters, but so do individual cities and towns. Some of those municipalities have rules that go beyond what is required by the state. (Permits and finals are required everywhere, by the way.)
Recently I found the requirements for the town of Los Gatos, and a couple of them surprised me, so I’m sharing the link here in case I’m not the only one caught a little off guard by it:
TOWN OF LOS GATOS WATER HEATER BRACING REQUIREMENTS (link to the town’s page)
San Jose’s requirements can be found here (for comparison and because they are pretty thorough by comparison to ours):
City of San Jose requirements for water heater installation (strapping, bracing, anchoring, blocking, etc.)
One concept that seems to differ between Los Gatos and San Jose has to do with the pressure release valve.
Los Gatos requirements for the pressure release valve state:
“Pressure relieve valve shall terminate to the exterior, 6 in. to 24 in. above grade with a nothread fitting pointing downward. Minimum ¼ in. per foot downward slope shall be maintained at pressure relief drain line.”
San Jose requirements for the pressure release valve:
There is a full page, and 12 numbered requirements, for the temperature & pressure relief value (T & P). Item 6 conveys that if the water heater is in a garage, the T & P does not have to drain to the exterior: “When a water heater is located in a garage, the T&P drainpipe may terminate in the garage. The piping must extend from the valve to within 12 inches but not less than 6
inches above the floor and point downward.”
Los Gatos has no such exemption for water heaters located in the garage!
BOTTOM LINE: if you are replacing your Los Gatos water heater, you might want to double check the town’s requirements to be sure that yours will be in line with the requirements of the town. There are a lot of odd water heater strapping cases around Santa Clara County, don’t let your home be one of them!
