Why You Need a Pressure Tank with a Well

Posted on: 29 July 2015

If you live in a rural area, you will likely not be able to get your water from a municipal system. This means that, you will have to drill a well to get water for your home. To increase the pressure from your tap and to relieve the strain on your well pump, you will need to use a pressure tank.

What Is a Pressure Tank?

If you are familiar with air compressors, then you should be able to understand how a pressure tank works on a well system. An air compressor has a pump which forces air into the pressure tank, and this pressure tank helps to compress the air. In a well system, your well pump forces water into the pressure tank, which increases the pressure of the water. 

How a Pressure Tank Operates

A pressure tank will have a control valve with a built in start-up and shut-off setting. When you turn your faucet on, water flows out of your tank, and the pressure begins to fall. The start-up setting triggers the pump to start-up when the pressure falls to a certain point. A well designed system will continue to run while you are in the shower or while your sprinklers are running to provide a steady stream of water. Once you shut-off your water, the pump will keep running until your pressure tank reaches the maximum pressure setting, at which point it shuts off. 

Tips for Avoiding Waste

You don't have to pay a water bill with a well system, but you do have to pay for the electricity it uses. If you have a leaky faucet or pipe, the pressure from your tank is always leaking out, which means your pump is constantly cycling on and off. Not only will this waste electricity, but it will also increase the wear and tear on your pump and can cause problems with your water table since you are constantly pumping water out of it. Thus, you should troubleshoot your home plumbing for leaks. If you have a sprinkler system, you should also check for leaky valves.

A well system presents unique challenges that you won't find with a municipal water system. In order to maintain the pressure of your home water system, you should make sure your pump and pressure tank are working like they should. Leaks might be a nuisance with a municipal water system, but they can actually lead to break down with a well pump. A professional well contractor will be to diagnose and find well water pressure problems.
