WSP Pressure Tank - 21x62"

Have you replaced your pressure tank before only to face the same pump cycling issues again? The WSP Pressure Tank - 21x62" helps smooth out your well pump’s cycling and maintain steady system pressure, reducing wear and improving your water system’s reliability.

When Pump Cycling Keeps Coming Back

You’ve probably tried replacing your old pressure tank or adjusting the pressure switch, expecting the pump to stop turning on and off so often. Yet the quick cycling continues, wearing out your pump and causing inconsistent water pressure. You might also notice system noises or sudden pressure drops when you use water. These are signs your current tank isn’t holding pressure as it should, leaving your pump to start and stop too frequently.

How the Pressure Tank’s Control Head Works for You

The control head on this pressure tank uses threadless, quick-connect fittings for service and draining, making installation and future maintenance straightforward. Inside, it features a replaceable butyl air cell, which keeps an air cushion inside the tank. This air cushion absorbs pressure changes, so the pump doesn’t have to cycle each time you open a tap or flush a toilet. Because the air cell is replaceable, you won’t need to buy a whole new tank if it wears out, saving you time and money down the line.

Why Butyl Air Cell Media is the Right Choice

Inside the tank is a butyl air cell—this is a flexible bladder that holds pressurized air separately from the water. Butyl is more resistant to chlorine and corrosion compared to some other materials, so it lasts longer in well systems where chlorine is used for disinfection. This media helps prevent corrosion failures and degradation, keeping the tank’s pressure performance steady through years of use.

The Size and Capacity That Handle Your Water Needs

This pressure tank measures 21 inches in diameter and 62 inches tall, holding about 80 gallons. That means it can handle a service flow around 27 gallons per minute, which suits larger homes or light-commercial properties where water demand is higher. Its size provides a substantial drawdown volume—this is the amount of water it can supply between pump cycles, helping reduce how often the pump starts and stops.

Who Should Choose This Tank

This model fits well in large residential systems or light-commercial setups where pump cycling has been a problem and where steady water pressure is important. If your water use is lower or you have a smaller home, a smaller tank might be more efficient. Conversely, if you have a very large system or heavy commercial use, you may want to consider a larger tank than this one.

What’s Included with Your Purchase

You’ll receive the complete 21x62" pressure tank equipped with the quick-connect control head and the butyl air cell inside. The tank carries a lifetime warranty on the pressure vessel itself.
