WSP 21x62" Mineral Tank - Blue

The WSP 21x62" Mineral Tank - Blue is a durable pressure vessel designed to hold the media bed in your whole-house water softener system. Sized at 21 by 62 inches, it supports efficient mineral filtration and long-lasting performance, helping reduce scale buildup in your water.

The problem you’re living with

If your water softener’s performance is uneven or your system needs frequent servicing, the issue might be with the tank that holds the mineral media. You might see inconsistent water softness, or your plumber may have pointed out corrosion or cracks in the pressure vessel. Without a reliable tank, the media inside can’t do its job properly, leading to scale buildup that shows up as rings in your toilet tank, film on shower doors, or stiff towels.

Why it’s happening

The mineral tank is the container that holds the media bed—those small particles that treat hard water by capturing minerals like calcium and magnesium. Over time, tanks made of lesser materials can corrode, weaken, or develop leaks. This compromises the media, reduces flow, and puts strain on the entire water softening system. A durable, corrosion-resistant tank is essential to keep the media contained and your system running smoothly.

What it’s costing you to leave it

A worn or damaged mineral tank means your water softener can’t reduce hard minerals effectively. That leads to scale buildup, which shortens the life of your water heater and appliances, causes your soap and detergents to work harder, and leaves stains and residue you have to scrub repeatedly. Over time, the extra effort and wear add up, making everyday cleaning and maintenance more of a chore.

How this system fixes it

The WSP 21x62" Mineral Tank serves as a sturdy pressure vessel that securely holds the mineral media. As your water flows through, the media filters or conditions hard minerals, helping reduce scale. The tank’s tough polyglass shell resists corrosion and withstands household water pressure, keeping the media bed intact and effective. This stability supports consistent water treatment and prolongs your system’s life.

What this system can handle

This tank is sized at 21 inches in diameter and 62 inches tall. Its design fits most whole-house softener systems needing a larger media container. The polyglass construction provides enhanced corrosion resistance compared to steel or fiberglass alternatives, giving you steady performance even under continuous water pressure. The top opening makes media replacement and inspection straightforward, so your system can handle regular use without frequent downtime or service. If your current tank is smaller or showing signs of wear, this size offers extra capacity and durability.

What you actually get

You receive a blue polyglass mineral tank measuring 21 by 62 inches, designed to hold your water softener’s media bed securely. The tank features a 4-inch top opening for easy access to the media inside. It comes with a lifetime warranty on the tank itself, covering structural integrity and corrosion resistance. The control valve and electronics, which are not included, carry their own manufacturer warranties. Shipping within the U.S. is free and included in the price.

Is this the right size for you?

This tank suits households or facilities that require a media vessel of this specific size—larger than standard or compact tanks but not oversized for typical whole-house systems. If your system calls for a smaller or larger tank, you’ll want to choose accordingly. The 21x62" size is common for systems with significant water usage or higher hardness levels needing more media capacity to maintain performance.

Living with it

Once installed by your licensed plumber, this tank requires little maintenance beyond routine media replacement or cleaning as recommended for your softener system. The top opening design makes those tasks less cumbersome. The durable tank means fewer surprises or repairs over time, saving you effort. While you’ll need to maintain the media occasionally, the tank itself is built to last with minimal upkeep.

What it won’t do

This mineral tank is not a complete water softening system on its own. It doesn’t include the media, control valve, or electronics needed to operate a softener. It also does not remove bacteria, sediment, or chemicals. For those issues, you would need additional filtration or treatment components suited to your water quality concerns.
