Specifications
Standard replacement part for draining and winterizing large-format pool filter tanks. Precision-molded from UV-stabilized polymer, this heavy-duty plug ensures a watertight seal at the base of your equipment for pressurized operation.
Safety Warnings & Critical Care
- Hand-Tight is Right: Hand-tighten only to achieve a seal. If it drips, check the O-ring for debris rather than using a wrench, which can crack the plastic threads.
- Lube the Seal: Apply a light film of silicone-based lubricant to the O-ring before installation. This prevents the rubber from pinching or jumping out of the groove.
- The Winter Trick: When winterizing, store the drain cap inside the pump basket or the filter's internal manifold to ensure you don't lose the cap or O-ring.
- Chemical Resistance: Built to withstand harsh outdoor conditions and standard pool chemicals without becoming brittle or leaking.
