Fowl Smell From Shower Drain
I read a discussion on this forum that occurred in 2005. Several people noted they had sewer like smell coming from a single shower drain. Speedball1 had several suggestions regarding cleaning out hair or other biological material from the drain. Some of the questioners tried all the suggestions to no avail.
My situation is similar. I know it is coming from the drain because when I tape up the drain the smell stops. When I remove the tape after several days it is powerful. The drain has been snaked without finding anything. I have used various materials. Roebek (spell ?) drain cleaner / septic tank cleaner with live bacteria seems to eliminate the fowl smell for a couple days. Then it's back again. This has been going on for several years. The trap is always full of water and a plumber cut a hole in the ceiling below the shower and said the plumbing to the shower looked normal.
Any further suggestions or solutions from anyone?
Thanks,
Ernie
