I've posted about my sewer line that was sabotaged with mortar by a disgruntled former tenant. Now I am trying to learn what it is that I am dealing with underneath the concrete basement floor.
I have looked up "house trap" and floor drain and seen pictures/diagrams of them. But I still don't seem to understand the pipe from which I am removing dissolved concrete/mortar.
Here is what the basement is like:
The "footprint" of the house is approx. 36 ft. wide by maybe 25 ft. front to back. Built in Western Pennsylvania in 1955 by a tract home builder. It was a VA loan for my father, so plumbing must have had to be to some kind of code, right? Plus it is in a county that has had a Health Department with a Plumbing Division for probably over 100 years.
Back to the basement. First of all, the main sewer runs along the front street. There are manholes. It must be pretty deep because the yard at the front of the house is level with the street - walk straight up to the front door into the house. Once inside, down a flight of steps to the unfinished concrete floor basement.
On the back wall of the house (away from the street) is an old fashioned double concrete laundry tub. To the immediate left of the laundry tubs the main stack comes down the wall from above, draining a tub, 2 lavs and 2 water closets. It appears to me to be black cast iron. On the concrete basement floor about 6 ft. or so out from the laundry tray is a floor drain, which I realize has a trap.
Then, at a point on the concrete floor about 4 ft. out from the FRONT wall (which is on the sewer line side of the house) is a "hubbed" pipe with a threaded cap that sticks up out of the concrete about an inch or so. This happens to be located just to the side of the wooden steps that come down from the first floor of the house.
In addition to the floor drain over by the laundry try (about 15 ft. away from this "clean out pipe" I see no other clean outs on the floor i the basement area. There is a floor drain in the adjacent garage that does not appear to have been tampered with.
Any guesses as to what I am dealing with under the concrete as far as a house trap? I have been told that the pipe I have accessed and am diligently cleaning out of softened mortar goes down into the house trap. I understand that the house trap is a big U bend that water is supposed to lay in to keep out the sewer gasses. And that if someone dumped Sacrete into this pipe and then water dumped in on it that the entire trap could be filled level with mortar.
Also, just out of curiosity, what material would the underground plumbing likely be of? I'm pretty sure there was no ABS in those days. There is a drain line I can see coming from the kitchen sink drain that looks to be about 2" copper. And the first floor bathroom has been replumbed in black ABS ferncoed into the main stack.
If there was any "saving grace" in all of this, the water was actually shut off to the house at the time of the drain line sabotage. So the only water the SOB had to use was two gallon sized plastic milk jugs. (Thankfully did not realize there was/is 40 gal. sitting there in the water heater in the basement.)
But back to my question: Other than the U bend and this "stand pipe" associated with it, should the sewer line go on out the other side of the house trap to the main? Would there be any other traps?
How deep did they put the house trap underneath a concrete basement floor? (Trying to figure out the entire depth of this 'stand pipe".)
What is a Fresh Air? Where should one be if there is one. Should I be looking outside the front of the house about where the sewer line would come out through the wall for one as another potential source of sabotage?
Thank you in advance for any help with my questions. I am starting to understand some of this but could really use some info from a very experienced (older like me) plumber!
