Got a question if the Ponpc will in fact, change if I move the extank connection. So per my "drawing", if I move the extank connection to above (before) the boiler loop, will I now see approx 5psi at the boiler relief valve instead of the 25-26psi?
My understanding is that it Will
change. This system apparently blows the relief valve occasionally and I believe the PONPC location is the reason for that.
