Rotten egg smell Vaillant ecotec 837 boiler - bacteria?

[Blackcatgas]

Any open pipes from the old instalation that have not been sealed ?

Nice thinking, maybe the condensate just drops into an untrapped 1 1/4 pipe?

this is what i am thinking.

does the condensate pipe drain internally into a waste pipe?. it could be a loose connection.

where has the condensate pipe been taken to?????????

Are you sure this is not a natural gas smell? If you have concerns call the emergency gas service 0800111999 now and get them to make safe and call your gas safe registered engineer to carry out tightness test and full appliance check.

I'll have to have a look tomorrow to make sure but i did check this and i think it does tap into a 1 1/4 waste pipe. The smell doesn't come from there though, it's a good 2-3m away from the boiler. It'll still be worth checking though, will let u know

It's not natural gas i'm sure. The guy who fitted it did come back out and tested it and couldn't find anything, not sure if he did a tightness test though but will find out.

it could be a light fitting or socket or something dead on a heating pipe perhaps

 

[that bloke.]

does the flue go through a cavity wall? could it be coming from the cavity if it is?

Note the bit about "ocassionally a hot water heater . . ."

Solder contains about 1000ppm of sulphur as impurity BTW. Your nose can detect about 1ppm H2S.
