    Of all the rotten luck! My PVC drain system passed the rough-in pressure test. The slab was poured and I installed the above slab rough-in drain system. It failed pressures testing. After spending hours and days testing, I found exactly where the leak is.

    It is a small, pin hole size leak in a 3 inch PVC soil pipe joint under the slab. I can get to it with a wire from inside the stack pipe but, it appears that I will have to break through the slab to get to the outside of the joint.

    Is there any other way to fix the leak without breaking the slab?

    Not likely. What caused the pin hole? If it was shattered then there may be other damage you cannot see.
