WSP Valve Head (WSP-VH-3900)

Your water test shows hardness levels that stir up more than just numbers: the scale building inside your pipes, stiff towels that lose their softness, and the stubborn soap scum on shower doors. This valve head is the control center that keeps your treatment system running smoothly to handle those everyday troubles.

How Your Softener Knows When to Work

The valve head on your water softener is the brain that decides when the system needs to clean itself and get ready to soften more water. It uses an electronic control board paired with a 24V motor to manage an automatic backwash cycle. That cycle lifts and rinses the resin bed inside the tank, clearing out trapped minerals so your softener can keep doing its job efficiently. You set the schedule on the control board, which helps avoid wasting salt and water by regenerating only when needed.

What’s Inside the Tank Matters

Inside the tank, the softener holds high-capacity cation exchange resin. This resin is specially designed to target and reduce hardness minerals like calcium and magnesium from your water. When your water flows through this media, the resin swaps those minerals for sodium or potassium ions, softening the water. The resin’s high capacity means it can handle significant mineral loads before needing a rinse cycle, contributing to longer-lasting performance.

The Tank Size Fits Your Setup

We don’t publish a fixed tank size with this valve head because it’s designed to fit the tank you have or select for your system. When you order, we’ll confirm the exact configuration based on your existing or planned setup. This flexibility means the valve head works with a range of tank sizes and plumbing connections, letting you upgrade or maintain your water softener precisely.

Who This Valve Head Works For

This valve head is made for residential water softener systems. Its electronic controls and motor assembly suit a variety of household sizes, working with the tank and plumbing your system uses. Because it’s compatible with NXT2 and XT controllers, it can replace or upgrade a variety of existing control heads. If your household has a particularly high water demand or a custom system, check your flow rate and softener size to ensure this valve head fits perfectly.

What Comes with Your Valve Head

When you order the WSP Valve Head (WSP-VH-3900), you receive the complete electronic control assembly with its 24V motor and control board. This is the component that manages your softener’s regeneration and backwash cycles electronically. Since this product is the control head only, it does not include a tank or media, which stay in your current system.

Who this size is right for

This is a control head, so the size it suits is set by the tank it sits on and the service flow the house needs, not by the head itself. On standard residential porting that is a single-family home.

There is no published capacity figure for this item, so we size it from your water rather than from a table. Send your peak flow rate and a water test and we will confirm what you need - it costs nothing and it avoids buying twice.
