Features

Description

The Pentair 1.5″ Hi-Flow Valve Diffuser (SKU 271163) is a critical internal component for PACFAB 6-position multiport valves. It evenly channels water through the valve’s pathways, ensuring efficient filtration, backwash, rinse, and waste cycles. Over time, diffuser degradation can impair performance and cause uneven flow or pressure loss. Installing this genuine replacement restores the original design’s hydraulics and helps maintain valve reliability. The durable resin material stands up to pool chemicals and mechanical stress, extending the life of your valve assembly.

Pro Tip

While replacing the diffuser, check the diverter stem O-ring (Pentair 191479) and spider gasket (Pentair 271148Z). Replacing these at the same time ensures a tight seal and prevents leaks.

Installation Tips

Before replacing, shut off the pump and relieve system pressure. Disassemble the valve top, remove the old diffuser, and clean any debris. Position the new diffuser correctly, then reassemble the valve in the proper order (diffuser → spider gasket → diverter). After reassembly, cycle through all valve positions to verify smooth operation and proper sealing.
