Is a shut-off valve required at the cold water inlet to a mobile home water heater?

Thursday, June 14, 2018

A shut-off valve at the cold water inlet to a water heater is not required by HUD and many mobile/manufactured homes are delivered without one. If your water heater doesn’t have a shut-off valve, retrofitting one when you replace it is a good idea. The valve makes the job of flushing the normal sediment accumulation from the bottom of your water heater easier.

    But HUD does require that water heaters be approved by them for installation in mobile homes, and they are configured differently than a typical residential water heater. See our blog post What is the difference between a manufactured/mobile home water heater and a regular water heater? to learn more.

    Draining the water heater sediment every two years is recommended and will extend the tank’s lifespan. But, if you wait too long to do it, your water heater will remind you by making rumbling/gurgling sounds sporadically when heating.
