I've just moved into a house that has a combi-boiler installed. On firing up to produce hot water, there is a distinct egg like foul smell from the boiler. Any ideas what would be causing this?
You said you had just got the property so best get the boiler serviced as you dont no its history etc. A shower would tend to use min gas pressure but you could still have a flue fault . unless you shower waste passas above the flue terminal ?
Thanks for your advice, and here's a wee update for you.
It turns out that the "foul smell" is not coming from the boiler, but coming back up from an open, waste pipe sitting beside the boiler, that used to have a dishwasher hooked up to it. The shower cubicle (which is upstairs) doesn't seem to drain very quickly and you can here the water gurgling away from this pipe (which is downstairs). A minute or 2 later, the smell comes from the pipe. I presume there is a blockage somewhere. Anything obvious I can do?
