WSP Retention Tank - 24x80"

When you’re scrubbing the sink and bathroom fixtures, you notice the grime returns soon after cleaning. Chlorine or injected air treatments help, but they need time to work fully before water is filtered away. The WSP Retention Tank gives these treatments the contact time they require, improving your whole water system’s performance.

How Lingering Cleaning Tasks Signal Contact Time Is Too Short

Cleaning starts fine, but soon a film or residue comes back on shower doors and taps. You might find the smell or taste of treatment chemicals stronger than it should be, or notice your filtration system seems to regenerate too often. These are signs that chlorine or aeration treatments aren’t getting enough time inside your water system before filtration begins. Without that, the treatment can’t do its job properly, leaving you scrubbing more and filtering less effectively.

The Control Head’s Role in Managing Your Water Flow

This tank works with your system’s control head, which regulates when water flows through and when the tank refills. By holding water and chemicals for longer, it reduces how often the control valve needs to trigger a refill cycle. That means less frequent backwashes and regenerations, saving water and extending the life of your treatment system. The control head settings you choose determine how well this timing works for your household’s water use.

What’s Inside Matters: This Tank Holds, Not Treats

The WSP Retention Tank itself doesn’t contain any treatment media; instead, it serves as a reservoir. Its job is to hold the water mixed with injected chlorine or air long enough for chemical reactions to happen before the water moves on to filtration. This built-in contact time ensures that when water reaches your softener or filter, it’s already undergone the initial treatment needed for better effectiveness.

A Size That Supports Larger Homes and Commercial Use

At 24 inches in diameter and 80 inches tall, this tank holds about 120 gallons of water. That volume provides roughly 35 gallons per minute of service flow, enough to support large homes or light-commercial properties where water use is higher. Its corrosion-resistant design suits systems handling chemicals regularly, helping maintain durability and stable operation over time.

Who Should Choose This Tank and When to Consider Other Sizes

This retention tank fits well with bigger households or businesses needing steady chemical contact times without frequent system interruptions. If your water use is moderate or you have a smaller softener system, a smaller retention tank may be more appropriate. Conversely, very large commercial setups might require even larger tanks or multiple units to meet flow and contact time needs.

What You Receive and What to Expect Next

Ordering the WSP Retention Tank gets you a robust 24x80 inch vessel built to last, backed by a lifetime warranty on the tank itself. The control valve and electronics come with their manufacturer warranties. Shipping in the U.S. is free and included in the price. Once ordered, your local licensed plumber can install the tank as part of your existing water treatment setup. We’ll confirm the exact configuration to fit your water use and chemical treatment setup during sizing, ensuring you get the best performance.

Who this size is right for

This is rated for roughly 35 gallons per minute of service flow, which suits a large or light-commercial property.

Work out what runs together on a bad morning and size for that figure. Equipment starved of flow does not just run slowly, it stops treating properly.
