Hot Tanks have a built in Vent or Expansion
Chamber in the top of the tank except for WL270 (GF) units.
The Vent Chamber allows for expansion of the water when it
is heated.
The chambers are separated by a welded-in tank baffle.
Water always flows into the bottom of the tank and out the
top to the faucet.
The hot tank outlet tube has a restrictor in its base. This
ensures the reservoir is always full by allowing more water in
than out.
There is a small hole in the side of the tank outlet tube that
allows air and water to pass into the vent chamber as it is
heated.
Water in the vent chamber is suctioned back through the
outlet tube vent hole when water is dispensed.
Expansion of water as it is heated in the reservoir will push
the water out the faucet when the outlet tube vent hole
becomes plugged with debris or scale.
The small Outlet Vent Hole is susceptible to scale build up
and is a key indicator that descaling is required.
It is critical to descale the hot tank through the vent line and
outlet line on a regular basis to prevent this problem.
Descaling through the inlet and/or outlet lines only will not
clean the vent chamber and outlet vent hole properly.
