Why does the hot tap on my bath smell like rotten eggs

[stewart2000]

Hi,

i hope someone can help with this situation. Over the last week I’ve noticed that when running hot water for a bath it stinks of rotten eggs. This hasn’t happened before and seems
to have come nowhere.

We recently (about 6 weeks ago) had a couple of rads fitted in the house but I’m not sure how that could have caused this.

We have a combi boiler that’s around 15 years old (according the the plumber) and the pressure looks fine. It does make the occasional banging noise in quick succession but that’s been the case the whole time we’ve been here.
Any ideas on why this has started happening?

Is it only coming from the bath or every hot water outlet?

It only appears to come from the hot taps in the bathroom - the bath and sink. It’s not happening every time they’re on. So far it’s been twice in one week.
