4. Install pump onto the backwater pipe, using the 3/4” female fitting and gasket ensuring
that the pump shaft is horizontal. The pump should be installed so that the pump is
pumping away from the hot water heater, towards the house. Confirm the direction
of pumping by observing the flow arrow on the side of the pump housing. Be sure that
the pump is not touching the exhaust vent piping (chimney) of a gas or oil-fired hot
water heater. (See Picture #2)
5. Connect the backwater line to the 3/4” NPT inlet of the pump. Use pipe dope or Teflon
tape to seal threads when connecting to a 3/4 female NPT connection. If a gasket
flexible copper water heater connector is used pipe dope or Teflon tape is not required.
6. Reopen the supply valve to the hot water heater and allow the water to run until all the
air has been purged from the piping.
7. Close faucet inside the house. page 2 Picture 1 Disconnect Direction of water
8. Plug the line cord of the pump into a 115V outlet. Be sure to route the power cord so
that it does not touch the exhaust vent piping of a gas or oil-fired hot water heater.
Key points of installation: remember to open the valve of cold
water pipe/hot water pipe/return pipe after installation.

The product is divided into three gears. When running, the gear is indicated by the
rotating speed of the light bar. The faster the rotating speed is, the higher the gear is.
When the water temperature of the pipeline is lower than 5
℃
for 30s, the electric pump
will operate until the water temperature meets 10C. If the water temperature can’t meet
10C, a buzzer will sound to give an alarm.
