CARE OF YOUR WATER HEATER
DRAIN WATER FROM WATER HEATER
Sand, silt, dirt, scale caused by hard water, and other sediments
in the cold water supply, collect in the water heater and settle
to the bottom. ONCE EACH MONTH, you should clean the
sediments and scale from the water heater so it will continue
to work efficiently. To clean out, do the following.
1. Fasten a length of garden hose to the drain valve. Put the
other end of the hose at the floor drain (FIG. 6).
WARNING
WATER FROM THE DRAIN HOSE MAY BE VERY HOT. BE
SURE NO ONE IS NEAR THE DRAIN HOSE OR THEY
COULD GET BURNED SEVERELY.
2. Open the drain valve and allow to run until water from the
hose is clear, with no more sediments.
3. Close the drain valve and remove the drain hose.
