Maintenance
Properly maintained, your water heater will
provide years of dependable, trouble-free
service. It is recommended that a regular routine
maintenance program be established and
followed by the user. Components, however, may
be subject to failure that require service. Failure
to use the correct procedures or parts in these
circumstances may make the unit unsafe or
reduce the life of the heater.
The owner should arrange to have the following
inspections and maintenance procedures done:
Before manually operating the relief valve,
make certain no one will be exposed to the
danger of coming in contact with hot water
released by safety relief valves. The water
may be hot enough to create a SCALD hazard.
The water released should be directed to
suitable drain to prevent injury or damage
Domestic water piping:
Yearly visual inspection.
Check all piping for signs of leakage at joints,
unions and shut-off valves. Remedy as needed.
Temperature & pressure valve:
Yearly Inspection.
Must be manually operated to ensure safe and
proper operation. Make sure that the discharged
water is directed to a suitable drain or some
collection method, and will not spray onto any
person. Use lever on the temperature & pressure
valve to open. A steady discharge of hot water
should be noticed. After releasing this lever the
safety relief valve should close and fully shut off
this flow. If the temperature & pressure valve
does not function properly, it must be replaced
with the same model or its equivalent. Do not
plug the outlet of this valve if a dripping condition
occurs.
Scale:
Monthly Inspection.
Scale problems occur rarely and under very
specific conditions. A domestic water flow rate
reduction may indicate scale build-up. A water
softener will prevent this problem.
A chemical cleaning process, however, is the
most effective process if done properly. If
chemical lime dissolving cleaners are preferred,
carefully follow the instructions supplied with the
cleaner. DO NOT use a muriatic or hydrochloric
acid (HCI) based cleaner. Be sure that the
manufacturer’s directions and warnings on the
container are followed. After treatment flush
cleaning solution thoroughly. Your plumbing
contractor should be contacted to clean the
heater of these deposits.
