Watts 7100681 Water Softener Metered Valve 30K Grain 9 Gpm

Product Description

The WATTS 7100681 is a metered control valve for residential water softening systems, built around the Clack PWSR130 valve platform. It manages the regeneration cycle by tracking actual water usage rather than running on a fixed timer, which reduces salt and water consumption compared to time-clock-based controls. Rated for 9 gallons per minute (GPM) flow and sized for 30,000-grain softener resin tanks, this valve connects via 3/4-inch female pipe thread (FPT) inlets and outlets. Licensed plumbers and water treatment technicians are the primary installers.

This valve is suited for single-family residential water softening applications where a demand-initiated regeneration control is preferred. The 30,000-grain capacity rating makes it appropriate for smaller to mid-size households dealing with hard water. The 3/4-inch FPT connection size is standard for residential softener installations and compatible with typical supply line plumbing found in those settings. It is commonly installed in utility rooms, basements, and mechanical rooms where the main water supply enters the structure.
