Gas and Electric Water Heater Parts
Dip Tube - The dip tube moves incoming cold water to the
boom of the tank. This process somemes causes
condensaon of ue gasses to occur which can cause a
sizzling sound when water droplets fall onto the burner
below. This occurrence is not detrimental to the operaon
of the water heater.
Drain Valve - The child-resistant drain
valve is located near the boom of the
water heater and provides a way to
drain the water from the heater for
maintenance purposes.
Anode Rod - The anode rod is a sacricial part installed to
reduce tank corrosion. A tank full of hot water acts very
much like a baery with small electrical currents owing
between the dierent types of metals. The anode rod is
made of aluminum or magnesium which is more
conducve than the steel of the tank. The electrical
currents corrode the anode rod rather than the tank.
T&P Valve - The T&P, or
temperature and pressure relief
valve, is a safety device designed to
relieve excessive pressure on the
tank prevenng it from bursng.
This valve also acvates to cool the
tank by discharging water if the
temperature inside the tank reaches 210°F. The T&P valve
must never be altered, restricted, or blocked as this
creates a hazardous situaon where the tank could build
up pressure and possibly burst.
Combinaon Dip Tube - The combinaon dip tube com-
bines the Dip tube and nipple into one part The combo dip
tube moves incoming cold water to the boom of the
tank. This process somemes causes condensaon of ue
gasses to occur which can cause a sizzling sound when wa-
ter droplets fall onto the burner below. This occurrence is
not detrimental to the operaon of the water heater.
