WSP 21x62" Mineral Tank

This 21x62" mineral tank is the pressure vessel that holds the mineral media bed in your whole-house water treatment system. It is built to last, resist corrosion, and keep your system running smoothly over time. A solid choice if you need a dependable tank to house your water softening or filtration media.

The problem with your current mineral tank

If your water softener or filtration system isn’t working right, the mineral tank might be the cause. Maybe you see uneven water flow, or notice the system needing frequent repairs. Sometimes tanks crack, corrode, or wear out, leading to leaks or loss of pressure. These tanks take a lot of strain and eventually fail if they aren’t made to handle it.

Why this happens

Mineral tanks hold the material that treats your water. They must withstand constant water pressure and contact with the media inside. Tanks made from weaker materials or with poor construction can corrode, leak, or break. The 21x62" size is a common, reliable dimension, but the material and design really matter. A tank that resists corrosion and mechanical wear will last much longer and avoid damaging your system.

What it costs you to leave it as is

A worn-out or damaged mineral tank can cause your water system to lose efficiency. That means harder water getting through, which scales up your water heater and clogs plumbing. You may spend more on soap and detergent, since hard water reduces their effectiveness. Appliances using water might wear out faster or use more energy. Plus, repairing damage from leaks or sudden tank failure can be inconvenient and costly.

How this tank helps

This tank acts as a durable shell for your mineral media, holding it under pressure while letting water flow through evenly. Its natural poly construction stands up to corrosion and wear, so it stays intact for years. The 4" top opening makes it easier to add or replace media and inspect inside without hassle. This steady environment helps your system soften or filter water effectively, leaving water treating media in good shape.

What this tank can handle

The 21x62" mineral tank fits many common whole-house systems. It supports standard mineral media beds needed for water softening or filtration. It works well under typical household water pressures and flows, holding enough media for a family-sized home. Compared to smaller tanks, it offers greater capacity and longer operating intervals between media replacement. It’s designed to be a versatile, robust vessel for mineral beds that need to last.

What you actually get

You receive a natural poly mineral tank measuring 21 inches in diameter by 62 inches tall. It includes a 4" top for easy access and maintenance. The mineral tank itself carries a lifetime warranty on the pressure vessel, covering corrosion and structural issues. Any control valve or electronics attached to your system carry their own manufacturer warranties, separate from the tank coverage.

Is this the right size for you?

This tank suits households or facilities requiring a larger capacity mineral tank, common in whole-house softening or filtration setups. If you have a smaller system or less demanding water treatment needs, a smaller tank might fit better. For very large or commercial systems, you may need a different size or multiple tanks. Confirm the size matches your existing setup and flow requirements before ordering.

Living with it

Maintenance involves periodic inspection and replacement of the mineral media inside, which you access through the 4" top. This might be every few years depending on water usage and hardness levels. The tank itself needs little upkeep beyond checking for leaks or damage. Because it’s lightweight compared to metal tanks, installation and handling are easier for your plumber.

What it won’t do

This tank is strictly the pressure vessel for holding mineral media. It does not soften or filter water by itself. You’ll need the appropriate mineral media and a compatible control valve or system to treat your water. It also does not handle disinfection, sediment removal, or chemical filtration. For those needs, separate equipment is required.
