Keep your Pentair pump housing fully sealed with the Swimables SW-21-131 Volute Drain Plug, a precision-crafted direct substitute for Pentair OEM part 071131. Tailored for WhisperFlo and IntelliFlo pool pumps, this plug forms a dependable, drip-proof closure that safeguards internal pump components during routine maintenance and seasonal winterization. The accompanying O-ring delivers firm compression against the housing seat, eliminating water seepage and preserving system pressure. Constructed from hardy, corrosion-resistant materials that endure constant chemical exposure and outdoor conditions, the SW-21-131 provides a budget-friendly, homeowner-installable alternative to factory drain plugs.
