Constant pressure vs. a traditional pressure tank

If your shower fades when the washer kicks on, this is why, and what a constant-pressure system does about it.

Ever notice the shower weaken the moment someone starts the dishwasher? That's a normal trait of a traditional well setup, and it's exactly what a constant-pressure system is built to solve. Here's the difference.

The traditional setup: pump + pressure tank

A standard well uses a pump and a pressure tank that fills to a high cut-out pressure, then lets the pump rest until pressure drops to a cut-in point (commonly around 40 and 60 psi). It's simple, proven, and affordable. The tradeoff is that your pressure naturally rises and falls between those points, and heavy demand can make it dip.

The constant-pressure system (CPS)

A constant-pressure system uses a variable-speed pump that adjusts on the fly to hold your pressure steady, no matter how many fixtures are running. It feels like city water. It's the setup we reach for most often in the Hill Country, and you can read how it fits into the bigger picture on our how a well works page.

Which is right for you?

A traditional tank system is a great, budget-friendly choice for many homes. Constant pressure is worth it if you value rock-steady pressure, run a lot of fixtures or irrigation at once, or have a multi-story home. We'll walk you through both when we spec your pump system.
