#2 INAIRID VACUUME AIR VENT

Just another Reason We will not ever do one of these conversions.

More headaches than I will ever need.

    We have converted a one pipe steam system to forced hot water,installed a coin vent on each radiator, upon filling the system we noticed air coming out of the 1-1/2 plug at the top of the radiator. At first we thought some had drilled a hole in the plug but after removing years of paint we noticed all the radiators have them. So we took a sawzall and cut one out and found a #2 Inairid Vacuume Air Valve inside. Howe do we get theses things out? We strip the brass nut trying to remove them with a wrench. Does anyone have a picture of one of these. It's 29 degrees here this morning and fortunatly the customer has a wood stove and the new boiler is heating the domestic water.

    Could you...

    drill and tap the orifice and put a plug in?

    Don't use a wrench! Use a socket.

    A picture or two, reduced to 600 pixels would be a help.

    Another \"gotcha\"

    which is why we don't do this type of conversion, and will not work on a system someone else has converted.

    These things are brass so they should be easy to cut out.

    I hope those are the only leaks you get......
