Product Overview

The Pentair 195829 filter drain plug is installed at the base of Pentair FNS and FNS Plus filter tanks and provides the drainage point for the filtration system. During routine service, the plug can be removed to release water from the tank before opening the filter housing or performing internal maintenance.

When the drain plug is securely installed, it seals the filter tank to maintain the pressure required for efficient filtration. Over time, drain plugs may wear due to repeated removal, pressure cycles, or chemical exposure. Replacing the drain plug restores reliable sealing and ensures proper drainage capability for Pentair FNS and FNS Plus D.E. filtration systems.
