WSP Pressure Tank - 21x41"

If your well pump starts and stops too often, causing noise and wear, a pressure tank like this one can smooth out those cycles. This model holds 47 gallons of water in a compact shape that fits where taller tanks won’t, helping your water pressure stay steady.

The problem

If you hear your well pump turning on and off frequently, or notice pressure fluctuations when you use water, it’s a sign your system isn’t holding pressure well. That can lead to sudden drops in water pressure at taps and appliances, and the pump working harder than it needs to.

Why it’s happening

Your well pump relies on a pressure tank to store water under pressure. When the tank’s air space is too small, or the tank corrodes and leaks, it can’t hold enough water under pressure. Without that buffer, the pump cycles on and off repeatedly to keep up with demand.

What it’s costing you to leave it

Short cycling puts extra wear on the pump motor, shortening its service life and increasing the chance of costly repairs. You may also notice higher electric bills since the pump runs more often. Pressure swings make showers less comfortable and can stress plumbing fixtures.

How this system fixes it

This pressure tank holds water inside a sealed vessel with a flexible air bladder. As water flows in, the bladder compresses, storing pressurized water. This stored water supplies your home between pump cycles, so the pump runs less often and pressure stays steady.

What this system can handle

This 47-gallon tank provides a generous reserve of pressurized water while fitting into tight spaces thanks to its wide, low-profile 21 by 41-inch size. It’s ideal where a tall tank can’t fit, such as crawl spaces or basements with low ceilings. The composite shell resists rust and corrosion better than steel tanks, so it keeps working reliably even in humid or damp areas.

What you actually get

You receive the pressure tank itself with a seamless composite exterior that won’t rust. The flexible captive air bladder inside maintains system pressure. The tank’s pressure vessel carries a lifetime warranty, giving assurance that the main component is built to last. Controls and valves that come with the system have their own manufacturer warranties.

Is this the right size for you

This model suits households or facilities needing a stable water pressure supply with limited installation height. If you have plenty of vertical space and want a taller, narrower tank, or if your water demand is smaller, consider a different size. For larger systems, a bigger tank might further reduce pump cycling.

Living with it

Maintenance is minimal. Periodic checks of the air charge inside the tank are recommended to keep pressure balanced, typically once a year. The composite tank doesn’t need painting or rust treatment. Any valve maintenance or replacement would be performed by your plumber as needed.

What it won’t do

This pressure tank won’t filter or soften your water, remove sediment, or treat bacteria or chemicals. If those issues affect your water, you’ll need dedicated filtration or softening systems.
