Hi could anyone advise - the toilet in our ensuite is intermittently very smelly. It is almost sulphurous sometimes. We have stopped using it, it is very clean (!) But still smells. Any ideas what the problem could be and who I need to call to fix it.
Look at the soil pipe. I expect it has been hidden away to stop you seeing it. I expect it has a Durgo or similar ventilation valve that is jammed, especially if the WC was connected clumsily to existing plumbing after the house was built. You need a plumber.
Thanks. We are hopefully going to replace the whole bathroom in the next couple of years, so living with it might be an option if it doesn't get any worse. There are multiple issues with the plumbing!!
