WSP Pressure Tank - Well Water, Inc Well-X-Trol

When you turn on a tap or flush a toilet, you’ll soon notice water pressure that stays steady, without the usual surge or drop. The WSP Pressure Tank – Well Water, Inc Well-X-Trol acts like a buffer in your well system, smoothing out the starts and stops of your pump and keeping water flowing evenly.

How Unsteady Pressure Feels in Everyday Use

You might see water pressure surging when someone else uses water elsewhere in your home — like the shower going from a strong stream to a trickle, or the washing machine causing taps to sputter. You may hear the pump kicking on and off frequently, sometimes in quick bursts. This cycling can be noisy and frustrating, and it means you’re constantly running your pump under strain instead of enjoying steady water flow.

What the Control Head Actually Does

The WSP Pressure Tank features an air-draw control head that carefully pulls in an air pocket inside the tank. This air pocket acts as a spring, compressing and expanding to absorb sudden changes in water flow. Because it uses a chemical-free oxidation process, it keeps the air clean and helps maintain reliable pressure without adding anything harmful to your water supply.

Why the Diaphragm Media Matters

Inside the tank is a pre-pressurized diaphragm — a flexible barrier that keeps the air separate from the water. This separation prevents air from dissolving into the water and causing waterlogging, where the tank loses its ability to cushion pump cycles. The diaphragm keeps the system responsive so your pump doesn’t have to work as often or as hard.

Tank Size and What That Means for You

This pressure tank measures 26 inches in diameter and 48 inches tall, holding about 86 gallons of water under pressure. Having this much reserve water ready means your well pump runs less frequently, which lowers wear and tear and extends its life. The tank’s size fits comfortably in most basements or utility rooms, giving you serious storage without taking up unusual space.

Who Will Benefit Most from This Pressure Tank

This tank suits large homes or light-commercial properties with well systems that need steady, reliable water pressure. If you have a smaller household or a less demanding water setup, a smaller tank may be a better match. Confirm your system’s peak flow rate and water use to ensure this tank fits your needs. It’s designed to handle service flow rates around 35 gallons per minute, ideal for busy homes with multiple bathrooms and simultaneous water use.

What Comes with Your Purchase and What to Expect Next

The package includes the 86-gallon pressure tank with a pre-pressurized diaphragm and the air-draw control head. The tank itself carries a lifetime warranty, giving you long-term confidence in the core component’s durability. The control head and electronics have the manufacturer’s own warranty. We ship from Tampa with free U.S. delivery included in the price. After ordering, you’ll receive your tank ready for your licensed plumber to install.

Who this size is right for

This is rated for roughly 35 gallons per minute of service flow, which suits a large or light-commercial property.

Check this against your peak demand rather than your daily total. A unit that is marginal on flow will drop pressure at exactly the times you notice it most.
