Hi guys
Thanks for all your comments
initially the system was leaking hot water through the flow pipe into the expansion tank.
Ball valve has been replaced tank still drawing in water.
we don't have mixer taps.
My only theory is that its the tvrs or the cylinder coil , flow...
We have recently had a condensing boiler fitted with TRV on every radiator now find expansion tank is constantly filling up.
Any ideas on what the problem could be ?
Many Thanks
