The FLOJET 2100 series pumps are automatic demand
pumps. They will automatically turn on when a fixture is
opened and turn off when all fixtures are closed.
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.
Model 2100-694 is a utility/shower drain pump. The
pump will not turn off automatically. Your shower drain
pump is designed to self-prime up to 6 feet suction lift
(vertical distance from shower pan to pump inlet). It is
recommended you utilize a “lighted” on-off switch so
that pump is turned off when not in use. The pump is
able to run dry (no liquid) for extended periods with no
damage to the pump, however this could cause
needless battery drain.
