Our shower does not have a p- or s- trap - it is connected directly to the sewer pipe in the basement, so we oftem have sewer gas smells in the bathroom. Can I install a p-trap anywhere along the "horizontal" run of pipe between the shower drain and sewer stack? It would be most accessible to install and service about 2 feet from the tub drain. Will this be a problem?
Also, I understand that by not peeing in the shower, I won't need a trap! I figured that response would be coming, though.
