Hi Guys im trying to completely understand my sytem, i have a wellmate pentair HP system which has the avc in it. its a bleed back system. when i had my plumber install it several years ago he put it in with a shrader valve on the top. for refrence here is the installation instructions.
heres my issue the insructions say that you should have a plug installed or a snifter valve installed on the top of the avc. im wondering if my plumber had done it completely wrong and thats why im having issues with my tank. they informed me that they need to bring th pressure up to 12 psi then add the water however in the instructions they say the opposite i should add water to the tank first and when the barbed npt fitting stops pushing out air i should fill the tank to the cut off psi manually after. secondly since its a bleed back system i have a snifter before my check valve so the water can bleed back obviously, however messing with it today i noticed that while the valve does allow air to go back into the well pipe to the house it is not letting it completely bleed back as when i press on the snifter stem after it has stoped sucking air it will suck air again for like 2 minutes. why would my valve not be completely drainging the pipe back. please help this is killing me to try to wrap my head around it.
