Looking for advice on whether I need to add a vent to the waste line
downstream of the toilet (~3') where the new shower will tie in. A few
feet upstream from the toilet is the sink and the vent for the waste
line tees in there . I'm figuring I need to but I'm going to have to
move a heater and wreck some sheetrock on the other side of the wall if
I do. Any ideas?
Thanks Rick

Yes, you really should tie the
shower drain back to the vent stack,
downstream of the shower trap.

But...in this case, you might get
away with a mechanical vent or
"air-admittance" valve:

Oatey makes one too.

If it matters, find out if the town will
accept a mechanical vent.

thanks, I'll tie it in!!

Horizontal wet venting (i.e., using the horizontal drain line as part of the
vent stack) is bad mojo. Usually against codes, too. You'll want to at least
route a vent from near your shower tie-in over to the vent stack by the sink (or
just go straight up through the roof...but that's typically a lot more work).

I was under the impression that the toilet must be downstream of the
other fixtures in a bathroom, am I mistaken?

Thanks, Wayne

When each fixture is individually vented, it doesn't matter.
