bleeding forever

Timco

Thanks to all for great advise...I am now insulated, and pumping away with swing check valves on both sides...Works great!

Question is that one wall mount rad always has the same amount of air in it, every day, but not much. Farthest away from the boiler, end of a zone, highest. I run at 20# and 180. Will this ever bleed out all the way? Had to replace all the water in the system last time due to making new inlet & outlet manifolds, about a week ago.

Thanks again for the great reads, posts, and advise. This is where the pros live and dwell, and the occasional HO.

Fresh water comes with suspended gasses. You should notice less and less bleeding .

Assuming you have a diagram expandtion tank or a Airtrol in a steel ceiling tank.

You are aware...

that "pumping away" does not mean from the boiler - but rather from the PONPC (point of no pressure change), the expansion tank connecting point, right?
