Is this the same coupling that comes in the installation kit?
Yes, the kit includes a rubber coupling along with PVC pipe and a wall vent part; this is the same coupling sold separately.
What pipe should I use with this coupling?
Incinolet specifies 18 in PVC vent pipe with 4 in interior diameter in the installation kit; match that size for proper fit.
Where does it install on the toilet?
At the rear vent collar; the manual instructs connecting the coupling and pipe to that collar before routing the vent outdoors.

If no damage is recorded and the shipment is accepted, the freight carrier will consider it delivered in perfect condition. In that case, we cannot issue a refund or replacement. This is a strict freight carrier policy and applies to all deliveries.

If there’s an issue with your shipment (whether it’s damage, missing parts, or anything unusual) please contact us within 48 hours of receiving the item.
