i live in austin, tx, and i've got a plumbing problem that's getting to be absurd. my line doesn't have enough fall to get to the street at 1/4"/ft. not even enough for 1/8". basically no matter how much i tweak the thing... and it has been countless tiresome hours of tweaking... it always has some section going uphill.
now this isn't because the city tap is too high or my house is too low, it's because the people who put the sewer line in the house originally had the bright idea to start it exiting the house at about 25" under the top of the foundation, all the way underneath the bottom of the concrete slab- this instead of going through the foundation with the pipe, exiting at a reasonable depth. i'm guessing this pipe was added after the foundation had been there for awhile.
i have an idea for a solution, but it involves tons of expertise and planning, so i want to run this by the pros first. what is the feasibility of drilling through the foundation to the toilet flange and putting in a whole new sewer pipe? i'm pretty sure it only feeds one toilet, which sits about 4' directly inside from where the pipe comes out. my primitive idea is to cut out the concrete around the toilet flange and remove the whole area. then try to drop a new pipe in, meeting it with a 4" tunnel drilled from the outside. i say drilled, because it's currently not an option to jackhammer the whole thing out. we would have to go under the shower, which has to stay operational in order for me to maintain my roommates.
i guess i can't embed images, so here's a link for the pics:
