Water heaters often make popping or gurgling sounds
Over a number of year’s sediment, scale, mineral and lime deposits gather on the bottom area of the water heater tank. When these deposits heat up, steam builds up in them and then the popping sound occurs. It is not dangerous but may be annoying at times.
Checking the temperature settings is advisable, for excessive temperature may also contribute to the popping sounds.
Draining the water heater may help reduce the popping sounds, for it helps to flush out some of the deposits that have gathered in the bottom area. Water heater manufactures recommend that this be done on a regular bases, for it helps extend the life of the water heater. They often recommend once a year. Another benefit is that the less deposits in the water heater, the more efficient the heating of the water; a cost savings on your water heating bill.
The water heater does not necessarily have to be replaced. Factors that affect this are the age of the water heater, how often it has been flushed, and how hard the water is in your area.
A second reason for the sounds
At times the sounds may be telling you that the water heater is getting old and nearing the age of needing replacement. Some buyers get a 1 year home warranty when they buy the house that will cover the water heater, should it go out in the first year of ownership. Another consideration is that the newer water heaters are more energy efficient and a cost savings may occur with replacement.
