- Use thread sealant or Teflon tape on pipe connections to ensure a watertight seal.
- Prime the pump and check for leaks once the system is reassembled.
Troubleshooting Tips
-
Leak at housing seam: Check that the housing gasket is seated properly and bolts are evenly torqued.
-
Air bubbles in pump basket: Verify that the suction side fittings are sealed and not drawing air.
-
Cracks or leaks around ports: Ensure plumbing is aligned properly and not putting stress on the housing.
