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.
- If inital installation of pool equipment, consider location to keep equipment 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 or improper 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. Ensure threadings are aligned and be sure not to force tightening. Over-tightening or forcing by 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 and ensure proper alignment before tightening. Over-tightening or mis-aligning clamp assembly can result in stripping threading on the locking clamp, or worse, damaging the filter tank or filter lid. 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: clamp assembly, filter lid, or filter tank bottom.
