I'm redoing a bath and want to swap out a shower and toilet.
Currently the toilet is at the end of a horizontal branch drain line and shares a wet
vent with the lavatory sink.
Following is a top view of the current horizontal branch (secondary) drain line of concern which (Y's) into the main line. Both the secondary and main line run
I use the following notation:
L - lavatory drain
WV - wet vent (2 inch) shared by lavatory and toilet
T - Toilet
S - Shower
DV - Dry vent (2 inch)
MAIN - Main Line (3 inch)
A top view of the current configuration is:
T -- WV ---- S -- DV -----------| MAIN
By swapping the Toilet and Shower I believe I'm not in code -- OR --
am I reading it wrong "A toilet is required to be at the end of the drain line"??
If not in code compliance, if I run a separate line parallel line to the current line with just the Lavatory and Shower on it and tie it in just before the dry vent , will this put me back in compliance?
