I'm not sure but thought you had to add air to bladder in tank. Also
sounds like a very small tank. I've had to have my tanks replaced about
every 10 years - the last one even though it seemed OK.



Normally The tank should not gain or loose air. If anything it may leak
out a small ammount of air just like your car tires.

I just can not undrestand why I have to let air out to matain the 38 psi
with the pump off and the water pipes open.

It would be similar to having to let air out of your car tires just to
matain the normal pressure.

That tank is somewhere around 5 years old.
I am not sure how much it should hold, but the tank is about 3 to 4 feet
tall and a foot and a half in diameter.


That is not as small as I thought. I think my old ones were that size
but newer is bigger. I never had to deal with putting air in and once
checked measured OK.
