I have a bladder-less tank (Amtrol RT42TT) with a Braukmann Auotomatic airvent. There are 1-1/4" fittings at the bottom. It is a submersible pump with a check valve.
The system has started short cycling and I have inspected all fittings and tested the tank and there are no leaks. My dilemma is that there is no air intake on the tank at the pressure switch or on the check valve.... Any advice is appreciated.
