Steam boiler

I have a steam boiler with the new auto feed System keeps on filling up with water and leaking out the steam vents Any ideas what could be the problem

    Sometimes the feeder doesn’t close properly. There should be an isolation valve before the feeder that you can shut. Either replace the feeder (with hydro level VXT only) or do away with it completely. You want to minimize how often the boiler feeds so unless you understand that, a water feeder can be a silent killer.

    need pictures. Is the boiler overfilling with water? Or is steam pushing water out the vents. Look at the gage glass.

    Shut off the water drain the boiler down to normal (1/2 glass)

    Could be a bad low water control operating the feeder. Need more information

    Brillant phraseology @Danny Scully !

    Permission to plagiarize?

    Never fill auto without a VXT...
