The other day the water was low on my gas boiler. I was at work, so my wife filled it. Now every time the boiler shuts off, there are 2 loud bangs in the boiler. There was also a gurgling sound which was kind of like a washing machine sound coming from it, but that seems to have stopped. We have had the bangs in the past, but they have always stopped after a little while. Should I try to drain the boiler a little and see if that works? It's coming from the boiler and not the radiators. Thanks.
