Replace Schrader Valve or Entire Air Vent?

[dlove]

get the pressure off the system, remove the valve and replace it with a small ball valve or bleeder valve, plug it...I hate those auto vents..I cant see a lot of air in the system once its up and running...this way they will not get any surprises when the valve blows off and floods the house.

Real men just do it on the fly with the system at full pressure.

Hell yes!!!! go getem its just water no freon here.....if ur going to drain the system plug the vent and install the honeywell air ELIMINATOR..if you ever use this, you will never use a bleeder again.

You have to let the pressure off but not totally drain it

LOL, I was just kidding in my above post. I closed all the loops, drained a little water out until the valve stopped leaking, then carefully removed the valve just to make sure I let enough water out of they system. Everything went well, and no mess, lol.

Also, let me that everyone for the replies!

Do you know any of them? One of the installers I help learned to lower the pressure on the boiler trying full pressure. I usually close the isolation valves and get some water out.
