Product Overview

The Pentair 24900-0503 drain plug provides the drainage point for Sta-Rite System 3 filtration systems. Installed at the base of the filter tank, the plug can be removed to release water from the tank during routine maintenance procedures such as cartridge cleaning or seasonal winterization.

When the drain plug is securely tightened, it seals the tank and allows the filter to operate under proper pressure. Over time, drain plugs may deteriorate due to repeated removal, environmental exposure, and chemical contact. Replacing a worn or damaged drain plug restores proper sealing and ensures reliable drainage capability for Sta-Rite System 3 pool filtration systems.
