Installation 5
Pressure hazard and risk of explosion . This
pump can develop high pressure when operated with the
discharge shut off or obstructed. For safe operation, we
recommend the following:
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. Run the
relief valve discharge to a floor drain or other drain that
will give adequate runoff.
Risk of flooding . Be sure that all plumbing
and fittings are rated to withstand the system pressure
which you expect the pump to generate.
Follow these instructions for a new installation. This text
may also be useful when replacing an existing water
pressure booster:
1. Decide where’s the best place to install the pump.
Think about these things:
• it must be near the main water supply line
• the pump must be accessible
• the power cord must reach a power outlet
• the pump’s LED lights must be visible
• ease of plumbing
• space saving
2. Mount the pump on a solid base in the location you
have decided on.
3. Choose a time that will allow you to shut off the
water to the household while you install the pump.
4. Shutoff the main water supply valve to
the household.
5. Open a nearby faucet to relieve water pressure in the
plumbing. Once the water pressure is relieved, close
the faucet.
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 pump. See Figure 2, which depicts
a typical installation. 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 inlet and discharge
threads. There may be 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, disassemble
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 pump 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 the system is drained, close
the faucet.
Sealing Pipe Joints
Use only PTFE pipe thread sealant tape or PTFE-
based joint compounds for making all threaded
connections to the pump itself. Do not use pipe joint
compounds on plastic pumps - they can react with
the plastic in pump components. Make sure that all
pipe joints in the suction pipe are air tight as well as
water tight. If the suction pipe can suck air, the pump
will not be able to pull water from the well.
