WSP Pressure Tank - 16x58"

After a shower, your skin feels smoother and your hair softer, thanks to steady water pressure that avoids sudden bursts or drops. A well-sized pressure tank helps your well system hold pressure and reduce pump cycling, smoothing out your water flow throughout the house.

How fluctuating water pressure affects your daily routine

That uneven water flow you notice—whether it’s a sudden drop when someone else turns on a tap or a sharp burst that feels like a brief shock—is the result of your well pump switching on and off frequently. This cycling can make showers less comfortable, cause your water pressure to surge or dip unpredictably, and put strain on your plumbing fixtures. You might also catch yourself scrubbing a ring of mineral deposits more often, and appliances like your dishwasher or washing machine may not perform as efficiently when water pressure isn’t steady.

The control head’s role in keeping water pressure steady

At the heart of this system, the control head manages when the pump runs by detecting water pressure. It decides when to start and stop your pump based on preset pressure limits that you or your plumber set. This automation reduces how often the pump cycles, saving wear and tear and energy. Because it’s a reliable mechanical system, it keeps your water pressure more consistent throughout the day and night, preventing the rollercoaster ride your faucets can sometimes take.

Captive-air media: why it matters for pressure smoothing

Inside the tank, captive-air acts as a cushion that holds water under pressure. This air space compresses as water fills the tank and expands as water flows out, absorbing the pressure changes that would otherwise make your pump cycle more often. This captive-air design is straightforward and dependable, well suited to smoothing out pressure for a whole house system, helping protect your pump from short cycling and premature failure.

Tank size and capacity: what 16x58" means for your home

This pressure tank is 16 inches in diameter and 58 inches tall, giving it a capacity of 40 gallons. That volume means it can store enough water to keep pressure steady in a large home, typically one with five or more people and three to four bathrooms. This size supports a service flow of about 16 gallons per minute, enough to handle multiple taps or appliances running at once without sudden pressure drops.

Who should consider this 40-gallon pressure tank

This tank suits households with larger water needs, such as families with busy mornings or multiple bathrooms in use simultaneously. If your well pump cycles frequently or you notice pressure fluctuations during peak use, this tank is designed to reduce those issues. For smaller homes or fewer people, a smaller tank might be more appropriate to avoid overspending and to match the system’s flow demands more closely.

What you get when you order from Water Softener Plus

Included is the pressure tank with captive-air inside, sized as described, backed by a lifetime warranty on the tank itself. That means the pressure vessel is covered for the long haul, giving solid peace of mind. The control valve and any electronics come with their own manufacturer’s warranty terms. We ship from Tampa with free U.S. delivery already included, so ordering is simple and transparent. After your order, our team will help confirm the right sizing for your water system, ensuring the best fit for your home’s needs.

Who this size is right for

This is rated for roughly 16 gallons per minute of service flow, which suits a large home - around 5 or more people with 3-4 bathrooms.

The number to match is peak simultaneous demand, not average use. Two showers and a dishwasher at once is the moment that finds an undersized unit, so size for that.
