container. After completely draining the water from the check
valve, clean the strainer by removing dust and dirt, set it in
the original position, and tighten firmly.

Removing the strainer from the hot water
supply pipe may cause hot water to spill out.
Take extra care when draining the hot water.
The drain nut and strainer should be
