Watts 7100495 Water Softener Metered Control Valve 45K Grain

Product Description

The WATTS 7100495 is a metered control valve assembly for residential water softeners rated at 45,000 grain capacity. It regulates regeneration cycles based on actual water usage, triggering regeneration only when the resin bed is exhausted rather than on a fixed schedule. This demand-initiated approach conserves salt and water compared to timer-based controls. The valve features a 3/4-inch female pipe thread (FPT) inlet and outlet connection and is rated for a service flow rate of 12 GPM. It is equivalent to the Clack PWSR145 control valve and is installed by licensed plumbers or water treatment technicians as part of a complete softener system.

This metered control valve is suited for residential whole-house water softening applications where consistent soft water demand requires efficient regeneration management. The 45,000 grain capacity rating makes it appropriate for households with moderate to high hardness levels. It mounts directly to the softener mineral tank and connects to standard 3/4-inch plumbing supply lines. Installers working on new system builds or replacing worn valve assemblies will find this unit a direct-fit option where a Clack PWSR145-style valve is specified.

Installation Notes

Installation should be performed by a licensed plumber or certified water treatment professional in accordance with local plumbing codes. Shut off the main water supply and depressurize the system before removing the existing valve or making any connections. Ensure bypass valves are in the bypass position before beginning work. Do not overtighten FPT fittings; use appropriate thread sealant rated for potable water systems.
