When starting from a completely drained system allow
time for the demand pump to fill the hot water tank. After
refilling the tank the pump is reprimed by opening a
fixture. Allow air to vent and close fixture when water
flow is steady. Faucet strainers and aerators should be
cleaned regularly.

. Y
our shower drain

able to run dry (no liquid) for extended periods with no
