Hello, long time reader, first time poster.
I recently moved into a home in Idaho that was built around 1970 (our jurisdiction uses UPC). The house utilizes a septic tank that sits relatively high; The main waste drain leading from the house to the septic tank sits about 40” or so off of the floor of the basement (see pictures below). The line and clean out are cast iron 3x3x3 Combo (not sure if this is the correct terminologyfor CI fittings). The clean out plug is a brass 2 1/2” fitted into a steel 2 1/2x3” threaded bushing that has been leaded into the flange of the CI.
One of the previous owners had replaced all of the house drain plumbing with ABS, and created a diagonal soil stack off of the CI cleanout combo, which then transitions to vertical. (The stack is then vented out the top with 2” ABS.)
The Cleanout/stack is located in a relatively large utility room, which is a poorly utilized space; we are planning on redesigning the space to add a bathroom to the basement utilizing a sewage ejector. (Will be breaking up the floor to install in ground drain piping) the utility room also houses the laundry units
In order to accomplish our redesign we would like to move the washer dryer to the orange wall, shown in the pictures below, requiring a new laundry standpipe to be installed. The current standpipe sits relatively high due to the current design of the houses main waste stack. Which leads me to my first questions:
1. Is there any issue with removing the clean out plug (as mentioned it is leaded in place, so will have to be cut out) and then using a Fernco donut in in the CI fitting to a drive 3” ABS stub, and then adding an ABS Wye (equipped with new cleanout of course)?
2. Is there a better option?
This wye will be used to install my sewage ejector discharge pipe.
I would also like to use the branch from this wye to run a new trapped and vented laundry standpipe. The current laundry standpipe is pretty high off of the ground, so much so that the washer’s permanently installed drain hose, barely reaches into the stack (forget about connecting an air gap). The current standpipe is also shorter thank 18”, due to this issue. The new laundry stack would sit at a point where the laundry drain line would easily reach without strain. (Pedestals aren’t an option as the units will be stacked, and the ceiling height is only 7ft).
The other option (maybe the correct one) would be to install a new laundry standpipe closet to the floor which would instead drain into the new sewage ejector pit. This would allow me to install the laundry drain stacks at a code prescribed height, but I’m not convinced this is the best option; I’ve been mentally opting not to do this to mitigate dumping additional sand/grit into the sewage ejector.
3. Should I be concerned with laundry grit being dumped into the sewage ejector?
I’m sure I’ll have some additional questions as my project progresses. Thanks in advance!
I apologize in advance if this is covered elsewhere, I searched the forum and was unable to locate similar threads (I’m certain this question has come up before).
