Why does the drain in my basement floor smell just like the raw sewage gas?
the smell is probably from the organic material in the drain decomposing, stuff like soap can stink horribly when left to “ferment”, mix bleach and water, 1 cup each, pour it in, let it set for a couple hours, flush it out with a pail of clean water, if it still smells repeat it. after it no longer smells after rinsing out, mix about 1/4 cup bleach with a cup of water and leave it in. this should be enough chlorine to keep it from smelling but not enough to make it smell like a Clorox factory is in your basement.
