I recently had more radiators installed, so the system was drained. Since that time, the noise of water being returned to the expansion tank in the loft has become excessive and can be heard from downstairs. The water re-enters the expansion tank at a fair rate of knots!!!! There are two tanks in the loft, so I assume that the smaller is the expansion for CH and HW and that the much larger one is the cold feed. I haven't had the CH on, so I don't know whether the prboblem is limited to just the HW. The boiler is a Potterton Netaheat. If parts are required, can they still be obtained?
Any help gratefully received - its driving me bonkers as it always seems to happen an hour before I get up! Oh for a good night's sleep!
