How to Aircharge Your Pressure Tank

Recharge Your Pressure Tank

  1. In order to re-pressurize your system properly you must know the cut in and cut out pressure settings. This is determined by running the water and watching the pressure gauge. When the pumping system turns on this is your cut in pressure.  When the pumping system turns off this is your cut off pressure. The standard settings are 20-40 or 30-50 or 40-60. Your determined amount of pressure is 2lbs less the cut in pressure(ex:40-60 switch would require 38psi with tank empty)
  2. Turn off power. This is done by switching off disconnect box to water/pumping system or by a breaker located in the electrical service box marked pump/water system.
  3. Turn off out going valve to plumbing.
  4. Bypass all water conditioning equipment. This is a very important step, to prevent plugging up conditioning units with sediment.
  5. Open a hose spigot or the sample tap to drain tank. Apply a small amount of psi with air compressor to snifter valve to completely evacuate pressure tank of all water.
  6. Turn off hose spigot/sample tap and add proper amount of air into tank Your system has now been re-pressurized.
  7. Switch power back on and allow pumping system to build up to the cut off pressure. Wait until the pumping system has completely turned off.
  8. Now open hose spigot/sample tap to drain again. Run water until clear of all sediment.
  9. Water conditioning units may be placed back into service.

You have now air charged your pressure tank. Congratulations!

Note:  You may experience dirty discolored water, staining or plugging up of fixtures after recharging a pressure tank. It is highly recommended that a trained technician air charge your pressure tank. Not only will it insure the job is done properly. With little ease he can also evaluate the rest of the pumping system to prevent further problems. The proper air pressure in your tank is one of the most vital parts of your well system. If it is not air charged properly it will result in premature failure of your well pump, not to mention low pressure and possibly a noisy system.
