Installation with a Chlorinator
The booster pump inlet port should be plumbed
as far away as possible from the chlorinator,
higher than the chlorinator and upstream of the
chlorinator (see the Typical Installation diagram).
Plumbing Configurations
The booster pump should be plumbed into the
system so it always receives positive flow from
the filtration pump. To ensure proper water flow,
please follow these guidelines:
1. The booster pump inlet connection line
should be at least 3/4" pipe.
2. Do not tap into the top of a horizontal line.
3. Use 90° street ells to minimize bends and
loops in the Polaris reinforced hose.
4. Follow our recommended plumbing
configurations shown below.

Checking Water Flow
Once the system is plumbed, it is important to
verify that there is sufficient water flow to the
booster pump. To check the water flow, turn on
the filtration pump. If there is no flow exiting the
pump inlet port, do one of the following:
1. Verify the installation is correct.
2. Install a ball valve on the return line after the
booster pump inlet.
3. Use smaller eyeball fittings in the return
lines.
4. Plug a return line.
5. If none of these suggestions work, contact
our Customer Service Department.
Booster Pump Hose Installation
1. Install the Softube™ quick connect into the
pump discharge and supply ports. Use clear
silicone as a thread sealant between the
Softube quick connect and the pump.
2. Measure and cut the hose. Make sure the
cut is clean and leaves a straight edge.
Avoid any unnecessary loops or bends in the
hose.
3. Push the hose onto the Softube quick
connect until it is flush against the hose barb
base.
4. While holding the hose in place, pull and
twist the sleeve on the Softube quick
connect over the hose as far as possible.
