B. Installation Basics
Plumbing Configuration
The booster pump should be
plumbed into the system so it
always receives positive water flow
from the filtration pump. To ensure
proper water flow:
• The booster pump inlet con-
nection line should be at
least 3/4 inch pipe.
• Follow our recommended
plumbing configurations at left.
Do not tap into the top of a
horizontal line; tapping into
the top of a horizontal line
may cause pump damage.
Note: If the plumbing configuration
causes tight bends in the Polaris
reinforced hose, use 90˚ street ells
to minimize the bends and loops.
Checking Water Flow
To check the water flow, disconnect the supply hose to the booster pump and
turn on the filtration pump. If there is no flow:
• Verify the installation is correct.
• Install a valve on the return line after the booster pump inlet. This valve
may need to be closed slightly.
• Use smaller eyeball fittings in the return lines.
• Plug a return line.
C. Troubleshooting
PROBLEM: Pump leaks.
SOLUTION:
Identify location of leak.
Seal Area
1. If the leak is at point A:
• Replace the seals and shaft
o-ring.
• When replacing the seals,
check the impeller seal
pocket. If it is damaged,
replace the impeller. If the
impeller seal pocket is dam-
aged, the pump was run dry.
Check that the circulation
pump is operating and verify
that the time clock sequence
is correct.
2. If the leak is at point B:
• Inspect the bracket for cracks.
• If cracked, replace the bracket and seals.
• If not cracked, replace the seals.
Connection Area
Check all intake and discharge hoses and connections:
1. Replace any cracked parts.
2. Check for hardened washers on old style (black) connections.
3. Reseal loose connections with rubber silicone sealant.
PROBLEM: Excessive vibration or noise.
SOLUTION:
1. Verify rubber feet are on the pump base.
2. Verify that the cleaner is installed (low back pressure causes
excessive noise).
3. Replace the hard plumbing with flexible hoses to dampen the vibration.
4. Check the impeller for foreign material.
5. Remove the wet end and run the motor alone to check for
excessive vibration.
