Help-Water Level Increases on its own!

in THE MAIN WALL
The water level of my system increases on its own...The system is manual feed...The valve is not leaking...I have shut down the house water main and the level increases anyway...I have flushed the low water many times while the boiler is at pressure and also while it is at zero pressure...The water is fairly clean. The system works great otherwise...No noise or water hammer at all...Nice balanced heat from the radiators...Any Ideas? I'm stumped.

    do you

    have a hot water coil in the boiler?

    Are you sure the feed valve is reallly closing ? Lots of old valves don't close properly after a time. I would install a nice new ball valve on the feed line if you don't already have one.

    Water Level

    I've got my eye on the ball valve...Its relatively new but you never know...I doubt this is the culprit though. thanks.

    Water Gain

    Thanks...The returns are not buried and the low water is blown down using a bucket...This is a strange problem...I need all the help I can get.

    Hot water coil

    I do have a tankless hot water coil...It is relatively new though, say 3 years...Think it may be leaking?

    Coil

    Isolate the coil and see if the problem goes away.....
