Hi (first time poster). When we've not used the bathroom sink for a few hours and then use it, we get a nasty smell from the bath plughole (i.e. first thing in the morning and after a day at work).
I've used plughole unblocker on the sink, shower and bath, and use hair plug covers in the sink and shower but still get the wiff / smell.
We've not replaced the bathroom but appears the sink connects into the shower, that in turn connects to the bath before the outlet. I know this because sometimes we hear or see water 'glugging' in the shower or bath when using the sink.
The outlet (c2-3") pipe runs into the rain gully for the kitchen extension. We've had a look and the outlet looks quite clear, apart from being a bit mouldy inside. The house was empty for about a year before we moved in about 3 years ago.
I'm wondering if it would help to clean all the pipes right through the system? What would I use, just bleach? What's the best way to do this? We could cap the outlet and flood the system.
Hi robm It may be the combination of a 2” deep bath trap and long waste pipe runs. Fitting a deeper trap may solve the problem but if space is an issue you may have to use a hepv0 type trap. Regards S.
