Back in March, we moved into a house which has a ground floor extension with radiators being fed from pipework from above. Thanks to this site, I found out that this was the reason why the small radiator in the bathroom always needed bleeding. I\\\'ve now fitted an automatic bleed valve to sort that issue out, but in doing this I found out there was loads of sludge in the central heating system and the expansion tank AND the ball-cock valve had completely seized on the expansion tank too!
Anyway, all sorted now (sludge removed, flushed etc.), but ever since, the hot water system seems to be making loads of gurgling noises when heating up the water. The central heating is now off for the summer, so I\\\'m not sure if the gurgling was happening before and the noises were just masked by the air gurgling in the central heating system or if these are new noises just associated with the hot water system. It almost seems like the hot water system needs bleeding. Can this be done?
