And the plumbers are DONE! Kitchen and dishwasher drains totally re-routed through new 3" pipe to the main 4"stack. And the washing machine drains into a mop sink that is connected to a basin pump that pumps it out through a parallel 2" pipe to the kitchen drain. It joins up about 2/3's (so as not to cause a vapor lock on the kitchen sink and backflow) down the main to the stack. Everything under the sink is now new 2".
The bedroom hole is filled in with concrete and when that is dry, we re-carpet.
