How to Know When You Need to Replace Your Constant Pressure Tank


Hi, I am Joe Fiorani. I am one of the senior techs here at Carroll Water and today I am here to explain when to replace your pressure tank.

One of the things I like to tell a customer is that they can perform a simple tap test. Basically what I’m looking for is where the water level is in your tank. The majority of this tank is full of air, so you’re going to hear that hollow sound.

When you get down to the water line, you’re going to hear a solid sound. If for some reason you’re hearing a solid sound in the majority of the top of the tank, usually that tank is going to be waterlogged. That’s when we recommend replacing it.

What can happen with a waterlogged tank is its going to create an issue with your well pump that we call short-cycling. You can check the gauge down at the bottom and if you’re running water of any sort and that pressure is bouncing up to your top, which is 60 PSI (usually), down to a 40, and it’s doing that a lot and its very frequent, then usually that is a bad tank.

That’s when you’re going to want to give us a call at Carroll Water and we can come out and replace your tank for you.
