How the Pressure System Works
The pressure tank stores water under pressure so that the pump does not need to start every time someone opens a faucet for a few seconds. As water is used and pressure falls, the switch tells the pump when to start. Once the system reaches the upper pressure setting, the pump turns off again.
If the tank is not functioning correctly, the pump may begin starting and stopping much more often than normal. That repeated cycling increases wear and can make the household pressure feel inconsistent.
Low Pressure Has Several Possible Causes
Weak pressure can result from a clogged filter or treatment device just as easily as from a problem with the pump itself. Valves, piping restrictions and pressure controls can also affect flow. That is why it helps to know whether pressure is weak throughout the property, whether the pump is cycling normally and whether the problem appeared suddenly.
