Compatibility & Installation Notes
This filter head is intended to replace the original top assembly of compatible Perflex D.E. filters. When installing, ensure the tank is depressurized, remove the existing head and gasket, clean the sealing surface, then install the new ECX11194AT head assembly. Re-tighten bolts in a star pattern, prime the filter system and inspect for proper operation and air release.
Troubleshooting & Service Tips
- Air present in system or poor filtration: Confirm the vent valve is functioning and the head bolts are evenly tightened.
- Leaks around filter head seam: Check the gasket seating, clean surface of tank top flange, and ensure bolts are torqued evenly.
- Head cracking or old plastic fatigue: Replace promptly to avoid catastrophic failure under pressure.
Why Choose This Replacement Head?
Replacing an aging or damaged filter head with the ECX11194AT helps restore factory-level integrity, restores proper venting of air, and supports safe, efficient filtration performance. This helps reduce downtime, prevent leaks and extend the usable life of the filter tank.
Maintenance Tip
Inspect the filter head and bolts at each service interval. Clean away any build-up or scale on the sealing flange, re-tighten bolts after initial operation following installation, and ensure the vent valve remains free of debris. Regular maintenance of the head assembly helps maintain peak flow and prevents air infiltration that can reduce system efficiency.
