Does anyone know of any companies that could repair a pushnipple leak on a steam radiator

    I dare say that most of us who have had the problem have done it ourselves.

    Here is a possibility.

    Purchase radiator stop leak at your local automotive supply house.

    Close the inlet valve to the radiator, make sure the stop leak is in liquid form . Remove the the vent valve from the radiator. Make a funnel with 1/8 or 1/4 nipple and elbow, increase ti at least 3/4" pipe with a 3/4" coupling and pour the stop leak into the radiator. Put enough of the stop leak solution to cover all the push nipples for at least a week. Then open the radiator valve and the solution drain back toward the boiler. Put the radiator back into service and hopefully the leak will have stopped.
