Hayward CX1750B Fits Hayward Star-Clear Plus Model C1750, C17502, and C17502S
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. Over-tightening locking knob can result in stripping threading on the locking knob, tie rod, or worse, on the base of the filter tank. This damage can cause the inability to tightly lock down the lid and will cause a leak and require replacement of any of the parts involved in locking down the lid: locking knob, tie rod, or filter tank base.
