I don't know your system but on mine the air relief is a small canister with
a small valve on top and a float inside that drops when air enters and then
reseals when the air level drops and the float rises to reseal. You have a
resealing problem, so either repair/replace the air bleeder. My system I
think it cost $10 US.
