Maintenance continued-
6. At least once a year, check the combination temperature and pressure
relief valve to insure that the valve has not become encrusted with lime.
Lift the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically (every 2 years) and replaced when necessary to prolong tank
life. Water conditions in your area will influence the time interval for
inspection and replacement of the anode rod. Contact the plumbing
professional who installed the water heater or the manufacturer listed on
the rating plate for anode replacement information. The use of a water
softener may increase the speed of anode consumption. More frequent
inspection of the anode is needed when using softened (or phosphate
treated) water.
10. The vent system must be inspected at least once a year to ensure against
leakage of exhaust products.
