I am having the sewer/drain fly problem in my house.
The house is a ranch on a slab. I have two bathrooms, one with a shower and the other a tub.
I had a local plumbing company come in to check this. They found a open drain in the shower and fixed it. (The shower drain pipe was simply hanging into the main drain line)
It has been three weeks since the job was done, but I still see drain flies in the other bath room where I have the tub. Should I have them check the plumbing under the tub?
Also, based on the details can you suggest if a camera inspection will help to tell if the pipes under the slab are cracked or broken? My local plumbing company tells me that the camera is too big to fit into a drain pipe. Is that true? It seems that the camera can only be used on the main sewer line.
Thanks and really appreciate your help.
