WSP Retention Tank - 24x73"

When you’ve just moved into a new home or facility and start checking the water treatment system, you might notice how tricky it is to get chlorine or other chemicals to mix properly before filtration. The WSP Retention Tank is designed to give those injected chemicals enough time to work effectively, improving the overall treatment process.

Settling into water that needs a little more time

The first sign you’re dealing with water that requires careful treatment is often subtle. Maybe the water smells slightly off or you notice a faint chlorine taste that comes and goes. These chemicals need time to mix evenly before the water passes through filters. Without that pause, the treatment won’t be as effective, and you could end up with inconsistent water quality. What you’re experiencing is the water rushing through without enough contact time for the chemicals to do their job.

How the control head on this tank works for you

The control head on top of the retention tank manages water flow and pressure to ensure your system runs smoothly. It regulates when the tank backwashes or regenerates, protecting the chemical feed process and avoiding waste. You get to set the timing based on your specific water needs, which helps save on chemical use and reduces downtime. Essentially, it makes sure the injected chemicals stay in contact with the water long enough to treat it properly before moving on.

Polyethylene media built to resist chemicals

Inside, the tank is made from polyethylene, a tough plastic chosen because it handles chemical exposure well. This means it won’t corrode or break down, even with repeated chlorine contact. The media’s purpose is not to filter or soften but simply to hold and retain the chemicals long enough so they can react fully. This kind of media is ideal for tanks focused on chemical retention rather than physical filtration.

A large, reliable tank built for continuous use

The standard size is 24 inches wide and 73 inches tall, holding about 120 gallons of water. There are two other versions too: a 31x55" and a 36x78" tank, offering different volumes and footprints. The size you pick depends on how much water your system processes and how much contact time the chemicals need. The tank supports a service flow of about 35 gallons per minute, making it suitable for large homes or light commercial setups where water use is steady and substantial.

Who should choose this tank size?

This 24x73" retention tank suits large households or businesses with a moderate to high water demand, especially those using chemical feed pumps in their water treatment systems. If your water use is lighter or your system smaller, the more compact 31x55" model might fit better. On the other hand, if you operate a bigger commercial site or require even longer chemical contact time, consider the 36x78" version. Confirm your flow rate and chemical needs with your local installer to pick the right size.

What you can expect living with this retention tank

Once installed by your plumber, the tank requires minimal maintenance. Its polyethylene construction resists corrosion, so you won’t need frequent replacements or repairs. Periodic inspection for leaks or damage is advised, but the lifetime warranty on the pressure vessel offers peace of mind. The control head settings may need occasional adjustment as your water use changes or system demands shift.

What this tank won’t fix

This retention tank isn’t a filter or softener. It doesn’t remove sediment, hardness, or other contaminants by itself. Its sole role is to hold injected chemicals like chlorine or air long enough to improve their effect before the water passes on to your filtration stage. For filtering or softening, you’ll need to add those components separately.

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.

Check this against your peak demand rather than your daily total. A unit that is marginal on flow will drop pressure at exactly the times you notice it most.
