Installation
6. READ STEP 6 COMPLETELY BEFORE STARTING WORK.
You must remove a length of pipe from the main
water supply line to allow installation of elbows
for the Automatic Booster Pump. The locations of
the cuts must take into consideration the size of
the elbows being used, the length of the threads in
threaded joints or the overlap in glued or soldered
joints, etc.. Position the elbows in line with the
pump suction and discharge threads. There may be
some water leakage while cutting the pipe. Remove
any burrs or shavings caused by the cutting tool.
NOTICE: Galvanized pipe may not need to be cut.
If there is a union close to the pump location, dis-
assemble the union and remove (unscrew) pipe back
past the pump location. Have new lengths of pipe
cut and threaded to allow for the pump installation.
NOTICE: Both female suction and male discharge
ports have 1" NPT threads. Depending on your type
of connection and the size of your home's piping,
you may need to install adapters on the ports.
7. Once the short piece of pipe is removed, the piping
above the cut can be drained to prevent water
mess. Place a pail under the opening going to the
household. Open the highest faucet in the system to
let in air so the water can fall out of the pipes into
the pail. Once it's drained, close the faucet.
8. Install the elbows in the main water supply line.
Point them toward the pump.
Risk of burst hose and flooding . Do not
install with flexible hoses. Use only rigid piping that
meets code.
9. Install piping from elbows to pump including a
union in each line, an elbow in the discharge line,
and a check valve in the pump suction line. The
arrow on the check valve must point to the pump
suction (see Figure 2). If not already in the plumbing
system, install a pressure relief valve in the pump
discharge line capable of passing the full pump
flow at 100 psi (689 kPa). If local code requires
installation of a pressure relief valve capable of
handling the full pump flow at a pressure less than
100 psi (689 kPa), follow the code requirements.
A low pressure safety cutoff switch should also be
installed in the discharge line, and may be required
by your local codes.
10. With all pipe and fittings installed and sealed, turn
on the main water supply slowly to pressurize the
system and check for leaks. If any leaks appear,
turn the main valve off, open a faucet to relieve the
pressure, and repair the leak. Repeat this step until
there are no leaks in the system.
11. Open a faucet to release the air from the pipes and
allow water to flow. When a steady stream of water
flows out of the faucet, the pump is full of water and
fully primed. Close the faucet.

12. Before continuing with the installation, see the
manual sections titled Electrical Connections,
Automatic Pressure Controller, Normal Operation,
and When Does The Pump Stop Operating for
detailed information on how the system functions.
13. At this point, you can plug in the pump for the first
time. When you plug in the power cord, the pump
will start and run for a few seconds.
14. When the pump stops running (after it shuts off
automatically), the system is at the boosted pressures.
Inspect the pipe and fittings again for water leaks. If
any leaks appear, unplug the pump, turn the water
main valve off, open a faucet to relieve the pressure
and repair the leak. Repeat this step until there are
no leaks in the system.
