NOT ENOUGH OR NO HOT WATER
The capacity of the hot water generator may have been exceeded by
a large demand for hot water.

Cold incoming water temperature will lengthen the time required to
heat water to the desired temperature.

temperature was warm, colder water creates the effect of less hot
water.
Look for hot water wastage and leaking or open hot water faucets.
Sediment or lime scale may be affecting water heater operation.
Refer to MAINTENANCE for details.
WATER IS TOO HOT
Refer to TEMPERATURE REGULATION.
WATER LEAKAGE IS SUSPECTED
1. Check to see if the drain valve is tightly closed.
2. The apparent leakage may be condensation which forms on cool
surfaces of the heater and piping.
3. If the outlet of the relief valve is leaking it may represent:

volume to equalize pressure with the main. A relief valve must
release this water or the water heater or plumbing system will
be damaged.
When such a condition is encountered, local codes or inspection
agency should be consulted to determine which system is acceptable
in your area. These my consist of:
