When I redo the kitchen, (Hopefully this year) I will be fixing this mess that was left by the previous owner.
There is the 4X4X2 tee visible in the pic which handles the kitchen sink drain. There is another below it that connects a branch that drains a bathtub, sink, and clothes washer. Below that is another 2 feet of PVC, then back to cast. The PVC is just sitting on the cast and held in place by another fernco. There is no hub below this pic before the pipe goes underground. It is not accessible enough to dig down to find the next hub.
Now, The cast line above the picture needs to stay. (Toilet is the only thing that drains from above this pic) How would I go about correcting this?
My thought is:
1. Clamp/support the cast line so it doesn't move and supports the line above. (How do I do THAT!?)
2. Cut the cast about 2-3 feet higher than the Fernco
3. Where the cast was removed, add two 1/8 bends and rotate them to create the proper offset
4. Add a cleanout above the tees, below the 1/8 bends? (I have no cleanout in the house, just one in the yard that angles towards the street)
4. Replace the Santees with new ones that will be faced the way the new kitchen /tub drain branches will enter the stack
5. Blelow the tees, reconnect the PVC to the cast that goes into the ground w/ a banded coupling.
But, if I do it this way, can the PVC take the vertical load of the stack on it? Is there something that should be used to support the stack to keep the weight off of the PVC? is it OK to just rest the PVC on top of the cast not at a hub?
Or is this a no-no, and the only way is to transition back to cast where there is a hub? (IE: Dig down until you find one!)
