WSP Pressure Tank - 21x62"

The WSP Pressure Tank - 21x62" is a durable 80-gallon composite tank designed to smooth out well-pump cycling and maintain steady water pressure in your home. It helps protect your pump and reduces wear by holding a reserve of pressurized water.

The problem you’re facing

If your well pump runs frequently, turning on and off in short bursts, you’re probably dealing with rapid cycling. This can cause uneven water pressure—maybe the pressure drops when you run multiple taps or the pump noise is louder than usual. You might notice that your pump seems to be working harder, or your water pressure fluctuates unpredictably during daily use.

Why it’s happening

This happens because your system lacks a sufficient pressure tank or the existing one isn’t doing its job. The pressure tank stores water under air pressure, so when you open a tap, water flows out smoothly without the pump needing to start every time. If the tank is too small, damaged, or doesn’t hold pressure properly, the pump cycles often to keep up with demand, causing the problems you see.

What it’s costing you to leave it

Frequent pump cycling means your pump runs more often and for shorter periods, which can shorten its lifespan and increase electricity use. Over time, this puts extra strain on your system, leading to more repairs and earlier replacement. You might also spend more time dealing with inconsistent water pressure or noisy equipment, and your plumbing may experience more stress from sudden pressure changes.

How this system fixes it

This pressure tank works by holding a reserve of water under air pressure. The tank has a flexible air bladder inside that compresses as water fills the tank. When you open a tap, water pushes out from the tank’s bladder, maintaining steady pressure and reducing how often the pump has to start. This smoothing effect protects your pump and keeps your water pressure stable throughout your home.

What this system can handle

The WSP Pressure Tank has an 80-gallon capacity in a 21" diameter by 62" tall composite shell, making it suitable for larger well systems that need a generous drawdown—the amount of water available between pump cycles. Its rust-proof composite construction means it won’t corrode like steel tanks, and the Quick Connect threadless fittings make installation and future maintenance easier with a range of plumbing types. It’s built to withstand regular use in demanding well applications, including those where chlorine is used for disinfection thanks to its replaceable butyl air cell.

What you actually get

You receive a pressure tank covered by a lifetime warranty on the tank itself. The control valve and electronic components are covered by the manufacturer’s standard warranty. The tank features Quick Connect threadless service and drain connections, a rust-proof composite shell, and a replaceable butyl air cell designed to hold air pressure reliably even in systems with continual chlorine use.

Is this the right size for you

This tank fits well for homes or facilities with a larger well system that experience frequent pump cycling or fluctuating pressure. If your water use is modest or your pump cycles are already minimal, a smaller tank might be more suitable. Conversely, if you have a very high water demand or an industrial setup, you may need to size up for even greater capacity.

Living with it

Maintenance mainly involves periodic checks to ensure the air bladder holds pressure and the tank connections remain leak-free. The composite shell resists corrosion, reducing the need for replacement compared to steel tanks. When necessary, the air cell can be replaced without changing the whole tank. Your plumber can handle installation and any future servicing thanks to the ease of the Quick Connect fittings.

What it won’t do

This tank won’t remove contaminants, treat hardness, or filter your water. It’s designed solely to smooth pump cycling and maintain pressure. For water quality issues like iron, sulfur, or sediment, you’ll need a dedicated water treatment system.
