One Basement Drain Blocked - New Homeowner
I don't have anyone to ask about my plumbing problem - I just moved into a house - the first time I'm responsible for my own maintenance after years of apartment living.
The shower in the basement (the basement was recently remodeled but I don't know if the shower was in constant use or not) started backing up into the drain outside of the shower a week after I began using it. It smells like sewage. The backing up and sewage smell appeared a few days later in the shower drain itself.
The weird thing is, I tried to snake the drain outside of the shower and it doesn't seem to have any holes leading anywhere (I put on a glove, reached around, and still couldn't find where it drains), and it drains very slowly. It's just about 3 inches deep. What is this drain for??
Every other plumbing fixture in the house works fine, including basement laundry, toilets, showers, sinks. Nothing else causes the basement drain to back up except the basement shower.
Is it a plug? A trap issue? Should I try the bleach/hot water method? I just don't know where to start and I don't want to pay a plumber before trying to see what I can do myself. I have a second bathroom I can use in the meantime (also, there is no toilet in the basement, just a shower).
I know I'm pretty clueless, but info on the "mystery drain" or different troubleshooting tips would be so appreciated.
