Hi All, Having A little Problem Fixing A CH System.
Its an open System, 3 port valve, changed the 3 port yesterday as the body was passing on it, system filled up a treat, waters totaly clear.
when the pump runs its fine for a few seconds then you hear air in it, i changed the pump as it was an old weak thing to begin with, not has a grundfoss on it, tryed fitting the pump backwards to forece the air up and out still no luck.
open system on one level, header tank in loft looks like its a close coupled system, no blockages anywhere, pipes run from tank along 2-3 meters in loft then vertically down to pump pumping downwards to 3 port valve next to cylender (which has a working auto air vent)
any advice?
cheers
