Pentair 178553 Filter Lid fits the following filter models:
- Clean & Clear 50 (CC50)
- Clean & Clear 100 (CC100)
Pro Tip:
There are 3 main causes for filter tank lid failures because of cracks or leaks that require filter tank lid replacement:
- Cause #1: Pressure gets too high in the filter tank resulting in a stress crack in the tank lid
- Solution: Monitor filter pressure gauge. Pressure at 20 PSI or higher indicates the pressure is too high. Clean off filters thoroughly. After cleaning, confirm pressure gauge shows less than 12 PSI, else replace filters. Clean out pump leaf trap and skimmer basket.
- Cause #2: Filter tank location is exposed to all the elements: sun, rain, cold, heat.
- Solution: Consider having some sort of "protective cover" installed to keep the filter unit out of direct exposure to the elements.
- Luckily, my pool equipment was installed next to the house and under my balcony. 25 years and never had an issue.
- Cause #3: Over-tightening can cause a crack on the tank lid at the fitting location.
- Solution #1: Pressure gauge and air relief assembly fittings should only be hand tightened when installing/re-installing to filter tank lid. Over-tightening using a wrench may cause a stress fracture on the fitting on the tank lid resulting in a leak.
- Solution #2: When removing and re-installing the filter lid for filter maintenance, do NOT over-tighten. DO NOT use a mallet/hammer to tighten lid. This will damage threading of the lid and/or filter tank resulting in damage that will cause a leak and require replacement.
Specifications
Pentair 178553 filter lid serves the following primary functions:
- Bottom side of the filter lid has a rectangular opening where the top sealed end of the filter core fits in to to allow use of the air release valve as well as, and more importantly, to plug the top end of the filter endcap causing the direction of the hydraulic pressure to force water thru the filter cartridge.
- Together with the genuine Pentair filter tank, tank locking ring and o-ring, the filter lid acts to contain the hydraulic pressure in the filter while preventing leaks.
- The lid enables the use of the pressure gauge for monitoring of the amount of debris captured in the filter cartridge.
- The lid enables the use of the air release valve during maintenance. It can be used BEFORE opening the filter to reduce the internal hydraulic pressure, making it easier to remove the filter lid. It can also be used AFTER completing maintenane and restarting the pool pump to remove air from the pool system.
