 B2b toilets
Author: Bmillz2281 (IL)

I’m remodeling 2 bathrooms that have back to back toilets. The house was built 50 years ago or so. The two bowls have a sanitary Tee branching off to them. The tee is horizontal though. So can I just replace it with a 45’ wye and call it a day? Or do I need to make them both individually hook up into the line?

back to back toilets SHOULD have been connected with a Double 'Y'

so, if it fits, you are good to go

bernabeu I understand for B2B toilets that are stack vented they have a special fitting for it called a DOUBLE FIXTURE FITTING or FIGURE 5 FITTING which is kind of between a sanitary cross and a double TY/combo. It still serves the purpose for venting like a sanitary tee but does not have the issue of sanitary tee allowing a snake from shooting across to the opposing fixture. Although I have never seen such a fitting in person.

a double fixture fitting will NOT 'pass muster'

B2B requires a double 'combo Y' or a double Y AND two 1/8 bends

both the 'flow' and a snake MUST be directed 'downstream'


back in the old days we called 'em 'batwings'


double Y & 1/8 bend (combo) fitting
as opposed to
double sanitary T fitting


of course, back then, we also had 2X6 'wet walls'
