We have just had our basement lowered and a new concrete floor installed on top of new drains for a three-piece bathroom and a water heater/furnace room.
A sewage ejection pit was installed in the concrete and needs to be connected to the main drain/stack. The stack itself also needs to be moved. It is no longer underground and it needs to be run between the joists in the ceiling.
We also require plumbing rough-in from the stack to a future powder room on the main floor. And, we need to run a pipe from one of the new basement in-floor drains to another location in the basement for the washing machine/laundry sink.
