Fleck 5600 Metered Control Valve: metered control valve

What it does for your water

The Fleck 5600 Metered Control Valve is a metered control valve. Connections: 2.5 in.

Metering means it waits for the gallons, not the calendar: regeneration starts when the programmed capacity is used up.

Most owners set the regeneration for the small hours; the house is on bypass water while it runs.

A replacement head must match the tank's thread (most residential tanks use 2.5-inch 8-thread), the distributor tube diameter and the injector size for the tank diameter. Parts that name it are in the valve parts lookup.

The listing also gives connections 2.5 in; model 5600-M; material Noryl, rubber; valve Fleck 5600.

The listing gives a shipping weight of 4.6 lb and complete system in the box.
