I recently bought a 5 year old, 4 bedroom ranch home with 2 full baths. In the master bathroom we have a tub and a separate shower stall. The jet tub is fine - however every morning I take a shower and open the shower door to the sewer smell. It is not real heavy but I notice it.
No problems with the tub or the other bathroom - just this one shower - is there something I can poor down it. There are no links in the basement under it or broken pipes.
Let me know
