I have a washer currently draining into a utility tub sink. We heard a horror story about kids putting toys in the sink and the washer drainage flooding the house. I want to remove the drywall to install a washer housing unit. We have PEX plumbing.
Is the following more or less the right idea?
- Turn off water to house
- Cut existing utility tub drainage PVC pipe and install a wye or tee fitting.
- Install a P trap
- Install a standpipe, connect to washer housing unit
- Reroute PEX water supply lines up to washer housing unit
- Put drywall back on
Since I assume the existing utility tub drainage pipe is properly vented, routing the new drainage into that existing pipe should be ok, with no additional connections, yes?
