3.  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 temperature-pressure relief valve several 
times until the valve seats properly without leaking and operates freely. 

 
4.  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 for any reason. 

 
5.  Monthly, drain off a gallon of water from the water heater to remove silt 

and sediment. 

 

 
6.  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. 

When lifting lever of temperature-pressure relief valve, hot water will be 
released under pressure.  Be certain that any released water does not 
result in bodily injury or property damage. 

WARNING! THIS WATER MAY BE HOT.
