Gould BF03S pump with bladder tank
Our lakeside summer camp has a 40 +/- year old Gould BF03S pump, pumping from the lake. The BF03S is a non-submersed shallow well pump with a float Type air volume control. Within the last few years a Sears 19 gal captive air bladder tank was added to the system. Operationally there are no problems, we have good water pressure and the pump cycles fine.
This winter I have rebuilt the BF03S. I have noticed a small leak in the diaphragm of the air volume control. This is a float type AVC, which operates a an air bleeder valve to activate a second valve to inject air on the suction side of the pump. Anyway, given there is a bladder tank in the system, do I even need the AVC on the pump? I am wondering if I do need to replace it, or can I just cap it off and go without it. Not sure if the AVC is needed for anything if there is also a bladder tank. But also, "if it ain't broke" applies, as the pump seems to work great with AVC and bladder tank.
Thank you.

Yes I suppose it is very possible that the AVC has not been functional at all. But should I go ahead and remove it, or is it worthwhile to restore its function.
That big bulb on top of that pump is a regular hydro pneumatic (non bladder) type tank. It needed air to work properly. But since you added a bladder tank you don't want to add any air to the system and just let the bulb tank get waterlogged. So I would remove the air injector so it can't work.
Thank you for the replies, that's what I needed to know. Great forum here.
