Installation & Compatibility Notes

Before installation, turn off the pump and relieve system pressure.

Once assembled, restore flow and check for proper alignment, secure seal and leak-free operation.

Maintenance Tips

Inspect the O-rings annually for signs of wear, compression or cracking — replace if needed.
Verify lock-nut and connector alignment each service interval—loose or misaligned fittings can lead to leaks or air intrusion.
Keep this kit in your parts inventory to reduce downtime during filter servicing or retrofits.
