I have lived in my house for 11 years now. For the past couple of months I hve been experiencing rotten egg smell on the first floor between the airing cupboard and bedroom which is also next to the bathroom. It's a new build so have had no refurbishment done. The smell sometimes appears when I have the heating on or run the hot water. Sometimes neither of them and the smell still appears. In January this year, I had British Gas out and the fixed a 5 bar water pressure to the main under the sink. Recently in March Anglian water did some ground work which lasted over 3 nights. One night they came across a problem which took them longer to finish within their time scale. I've had this smell come and go for a month now and don't know who to call out. please help.
