currently working on an ideal open vent system, open vent and cold feed come down the wall and connect somewhere under the bath, so i have to pull the bath out to find exact connections. flushed the system and rads got hot while i had both feed and vent capped. now i run heating and the vent pipe is sucking.
any quick fixes, i think the open vent is on the return
if i combine the cold feed to it will it solve the problem???
