WSP Pressure Tank - 16x58"

The WSP Pressure Tank - 16x58" is a 40-gallon composite pressure tank designed to smooth out well-pump cycling and maintain steady water pressure. Its corrosion-resistant build helps protect your pump and provides reliable pressure for your home’s water system.

The problem you’re facing

If your well pump turns on and off frequently, you’re likely dealing with pressure swings that affect your water flow. You might notice pressure dropping suddenly when you open a tap, or the pump cycling loudly every time you use water. These constant starts and stops can be hard on your equipment and annoying around the house.

Why does this happen?

Your water system needs a buffer that holds water under pressure, so the pump doesn’t have to run every time you use a small amount. Without this buffer, the pump cycles rapidly, causing uneven pressure and more wear on the motor. The best way to check is to watch your pump: if it starts and stops more often than every few minutes during normal use, your system is short cycling.

What it’s costing you to leave it alone

Short cycling wears your pump out faster and uses more electricity. Over time, the extra strain can mean expensive repairs or replacing the pump long before it should need it. You also get uneven water pressure that can make showers less comfortable and appliances like dishwashers or washing machines run less efficiently. Plus, the noise and vibration from frequent cycling can be a constant nuisance.

How this system smooths pressure and pump cycling

This pressure tank holds water behind a flexible air bladder, storing it under pressure until you need it. When you open a faucet, water flows from the tank first, keeping the pressure steady and delaying the pump from starting. This reduces the number of times your pump cycles on and off, easing the load on your pump and keeping your water pressure more consistent.

What this tank can handle

The WSP Pressure Tank - 16x58" offers a 40-gallon capacity in a slim 16-inch diameter that fits well in tight spaces. Its composite construction resists corrosion and condensation sweating, making it well suited for humid environments and long-term use. The tank can handle the pressure demands of most residential well systems, reducing pump cycling to protect your investment and maintain smooth water delivery throughout the home.

What you actually get

You receive a composite pressure tank covered by a lifetime warranty on the tank itself. The tank’s durable, rust-proof shell and flexible air bladder work together to store water under pressure. Control valves and any electronics included carry the manufacturer’s separate warranty terms, ensuring you know exactly what’s covered.

Is this the right size for you?

This 40-gallon tank fits most private well systems for single-family homes, especially where pump cycling is an issue. If your water use is unusually high or your system is larger, you may need a tank with a bigger capacity. Conversely, smaller homes or less frequent water use might do better with a smaller tank. Proper sizing is key to maximizing the tank’s benefits.

Living with the tank

The composite pressure tank requires little maintenance beyond occasional pressure checks to ensure the air bladder is properly charged. It’s lightweight for easier handling during installation by your plumber. Thanks to its rust-proof design, you won’t have to worry about internal corrosion or condensation problems that add upkeep time and cost with steel tanks.

What this tank won’t do

This tank won’t filter or soften your water, remove sediment, or fix water that smells or tastes off. It’s designed solely to manage system pressure and reduce pump cycling. For other water quality issues, you’ll need additional equipment suited to those specific problems.
