Smelly drain in apartment
Hi,
I live at ground floor of my apartment block. Few months ago, my ensuit toilet started to smell really bad. I called the developer, and original builder couldn't find the reason why. Here I am, trying everything on my own. Bleach, flushing water down everyday for at least 5 minutes, enzyme….Everytime the plummer is trying different method of approach, so far nothing has worked.
My bathroom drain is linked with my shower, bath, sink in one. The plummer mention it might be the pressure in the bathroom, because of my fan.(desperate approach in my opinion) Everyday when I get home the bathroom is really humid and warm, esp. a hot day, no wonder there'll be a smell. I think the drain is leaking, so the sewer gas is somehow coming back up from the drain.
Please please help me with the situation!
If there're more test I can do to identify the issue?
