What's a Constant Pressure System? Part 1

Those of you with a conventional home well water system have probably grown accustomed to arranging your day around the inevitable rises and drops in water pressure. (Want a comfortable shower? Wait until the clothes washer fills up, but make sure the lawn sprinklers aren't on first!) However you may not understand why.

Inconsistent water pressure occurs because the mechanical pressure switch system is made to allow it. Basically, the system is doing what it was designed to do. It goes like this:

1) When you use some water, the pressure in your system's water pressure tank drops. 2) The drop in pressure mechanically causes a switch to turn on an electric motor which spins the pump in the well, pushing more water into the tank. 3) Soon, the pressure in the tank increases to its previous level and the pump motor is automatically switched off. 4) Then, as more water is used, water leaves the tank and...return to step one.


The conventional well system is shortening the life of your water pump.


This conventional type of system is simply not capable of providing a continuous level of water pressure. And that may be an inconvenience that you've learned to live with, but there's something else going on that is more than just inconvenient.

The repeated switching on and off of the water pump is damaging it. Here's how: The intense heat that's generated by the amount of electricity required to make the motor instantly spin the pump is harmful. Also, the pump is stressed each time it tries to suddenly push a column of water that was previously still. Bottom line: The conventional well system is shortening the life of your water pump.
