Sewer Backing Up at Clean Out?
Hi - I need help!
I noticed after a large storm that my garage was flooded (1/4") and stinky. I have had other flood water issues on the same floor because of rain water leaking into the basement - that issue is being resolved. (my house is a raised bungalow - front of house is grade level - and after 20' back is below grade - in a hill..)
I waited and let the issue resolve it's self, or so I thought, thinking it had something to do with the other problem...
Shortly after this I noticed that when I used large amounts of water, washing, showering, flushing... the same problem occurred but to a much lesser extent.
I located the cleanout in the garage & had to remove a thin plywood subfloor that covered the garage floor & hence the cleanout.
The clean out is located about 2' below the garage floor and the 18" x 12" pit was full of nasty stuff - toilet paper, tampax, sewage, baby wipes, a small plastic bag. The bag must have been flushed by a previous tenant of mine. A very messy job but I removed everything and properly disposed of it. YUCK!!
But what I found was that the sewer clean out cap had been forced off??? Pressure from a backup?
I'm assuming the cap had come off sometime ago - based on the estimated age of the 'archaeological finds'.... But no indication of water backing up in the garage before this - everything was always dry and clean.
I immediately stopped putting anything through the system.
I tried Root X in the pit. I rented a 50' electric sewer auger (long enough to get to the street) & brought up a few baby wipes & tampons etc. The water still came up to about 6" above the clean out.
I tried replacing the cap (after pumping out the water) and found that it wouldn't really go in properly (despite many attempts).
I filled the laundry room sink with hot water & bleach - the water still gurgled up slowly and after an hour or so the pit is full to about 6" above the clean out & appears as though it will remain there despite no use of water.
There is no 'sewer gas smell' (there was previously but not since) & the water is black/grey - but I'm assuming that is because it's in contact with the dirt surrounding the pipe.
I have next to no resources to resolve this problem & it's going to take me at least a week to clean out the garage well enough to let some one in to do the work. (I'm single, very busy working trying to make ends meet and I need to feel comfortable letting someone in)
If anyone could tell me what they think could have happened & what the really issue might be, how I should proceed from here & how much it might cost me to resolve it...
I WOULD BE GREATLY APPRECIATIVE!
