Greetings! I've appreciated the great advice from folks here over the years and I'm back for a quick check on my basement bathroom DWV plan. First pic is floor plan and where I'd trench, and second is my attempt at an ISO drawing. I'm in Virginia under IPC btw and this is a permitted project that will be inspected.
I had to scratch my head a bit because the 4" main drain runs under the bathroom (fairly deep, like 14"). I want to use the lav as a wet vent for the whole bathroom group.
I really want to double check elevations/depths of pipes. Again the 4" is pretty deep, and my plan is to have 3" from toilet at that same depth with the 4x4x3 wye flat. Since the 2" from shower has to cross over the 4" main it will obviously be higher, and I'd put the 2" from lav at same height, again with the 2x2x2 wye flat. Where the 2" line ties in/drops down to the 3" I'd have the 3x3x2 wye turned up (over 45d right?) to vent the toilet too.
I believe the only length issue here is that the 2" line from shower has to meet lav/vent line in less than 8 feet, correct?
Does anyone see any problems, or is there a more logical/easier way to pipe it?
Thanks in advance and hope all have great 4th weekend. Philk
