HELP!!! Flooding Steam Boiler

in THE MAIN WALL
My boiler continues to flood the sight glass despite having closed the valve for the automatic feeder and the cold inlet to the feeder and manual feed loop. The boiler has two tankless coils that were replaced two seasons ago. Could I have a leaking coil and if so how do I isolate the coils to check it out?

I probably will change the valves just to make sure there is no leak but I kind of doubt that both are leaking but the same question would arise on how two new coils are suddenly leaking and now flooding the boiler.

Help!!!

    Coil check

    After you make sure there is no leak by through a valve, I'd isolate each coil and pressure test each with some dry nitrogen. Very possible that you have a leak even with a new coil.

    Good luck-
