One of the common problems with having a well for you water supply is that you have the maintenance of the water pump and the related things that are necessary to make that all work. One of the most important parts of that system is the water well tank
or the water pump tank
. This tank is what keeps the well pump
from having to turn on and off every time you draw a few drops of water.
In the past the tanks were made with an air valve that injected just a bit of air into the tank every time the pump started. This helped to keep some air in the tank and also gave the annoying problem of air coming out of the faucet at times. To make this better well water pump tanks
are now made with a diaphragm that separates the air from the water.
This keeps the water cushion trapped inside the tank. That is great and makes the well tank virtually maintenance free as long as there are not holes in the rubber bladder that separates the water and the air.
There are some easy ways to tell if your well pump tank
is not working the way that is should work. And also here are some things that you can do to maximize the capacity of the tank.
- Drain all the water pressure out of your system. Then check the air pressure in your tank and adjust it to 2 PSI below the cut in pressure of your pump.
- Make sure that your pressure switch is giving you 20 PSI differential between the cut in and the cut out of your pump.
- Make sure that your tank is big enough to give you at least 2 minutes run time when your pump starts till it stops.
Now for pressure tank
- The pump starts and stops rapidly while you are drawing water. This means the bladder has failed in the tank and you have no air in the pressure tank. Replace your pressure tank.
- You get a slight hesitation as you are drawing water before the pump. This means that you have too much air in the tank and you need to release some air or increase the cut in pressure on the pressure switch.
- If in the summer time you see condensation more than halfway up the side of the tank then you have a bad tank. The tank should never be more than about half full of water. Replace the well pressure tank.
One note to consider. If you are not drawing water and your pressure drops rapidly when the well pump shuts off then it is NOT a pressure tank problem, it is a problem with the check valve in the pump.
This should give you a basic trouble shooting guide to your well water tank
or water pressure pump tank
