Fleck In / Out Head

The genuine Pentair Fleck In / Out Head is the inlet/outlet connection component that ties your Fleck control valve into the home's plumbing, providing the service-in and treated-water-out ports for the system. It carries the alternate part number FL61445-1. This head is the physical interface between your incoming hard water supply, the control valve, and the line that carries treated water back out to the house.

Every plumbed water treatment system needs a reliable, leak-free point where the raw water enters and the treated water exits. The in/out head provides exactly that, organizing the inlet and outlet ports into a single connection block that mates to the valve. Because all of the system's flow and pressure pass through this component, a sound connection here is fundamental to the entire installation. A compromised head can undermine performance even when the valve, media, and tank are all in perfect condition.

A Foundational Connection

Plumbing connection points endure a surprising amount of stress over the years: thermal cycling as water temperature changes, pressure swings each time fixtures open and close, and the mechanical strain of the original installation and any subsequent service. Over time a head can develop hairline cracks or its mating seals can harden and weep at the threads, leading to slow drips, reduced pressure, or visible leaks around the valve. Replacing the in/out head restores a tight, dependable connection between the valve and your water lines. When installing, inspect the mating O-rings and threads for damage, use the appropriate thread sealant or PTFE tape as specified for your fittings, hand-tighten and then snug carefully to avoid cracking the plastic, and pressurize the system gradually while watching for leaks. Always confirm this head matches your specific Fleck valve model before ordering so the ports and threads line up correctly. Because every drop of water in the system passes through this connection, keeping it sound is fundamental to leak-free, full-pressure operation, and replacing a worn head promptly prevents a small drip from becoming a larger problem over time.
