How to Fix / Troubleshooting
Safety first: Turn off power and relieve system pressure before working on the pump.
- 1. Identify crack location: Clean and dry the pump exterior. Look for visible cracks, especially around fittings, lid area, and drain plugs.
- 2. Temporary mitigation: There is no reliable permanent repair for a cracked housing using sealants. Do not rely on epoxy as a long-term fix on pressure components.
- 3. Replace housing: Plan to replace the SuperFlo pump housing/volute with a compatible Pentair part. This requires disconnecting plumbing unions or cutting and re-plumbing if unions are not present.
- 4. Winterization check: In freeze-prone areas, ensure proper winterization in the future by draining the pump and protecting it from freezing temperatures.
