water tank pressure is gaining air pressure

Home Handyman -------------------------------------
Hope this is the right place to add this article.
I have a 3 year old water tank in a home that has a well. Problem is the air in the bladder is increasing. Not sure how that can happen. But it does. I have drain the tank of water and adjusted the air pressure to 2 psi lower the kickon setting. Which is (40 PSI) As recommended. And in about 2 weeks or a month after the pump starts running right when the toliet flushes, etc. So then after I drain the water from the system and the tank, I put my pressure gauge on the valve on the tank. and it reads 60 psi. This is with the drain valve open. I then relieve the air back to 38 PSI start the water again again and every thing works great again. I do have an air-ation system which cleans the iron out of my water. This draws air in while the pump runs and works with the mineral tank. I need some good advice PLEASE!!!

Pump systems without an air bladder use a small air bleed on the pump inlet to supply a small amount of air to the tank along with the water. They use a float valve to bleed excess air out of the tank when needed. It may be possible for you to adapt such a valve to your tank.
However, I do not see how air in the water gets into the air side of the bladder unless the bladder is leaking.

grick8 had written this in response to http://www.thestuccocompany.com/maintenance/Re-water-tank-pressure-is-gaining-air-pressure-285645-.htm : Well the tanks says it is a 36 gallon diaphragm. If it is leaking wouldn't water come out of the air bladder valve? Thanks for your suggestions.

Must be a leaky bladder combined with that aeration system.
