We will be installing a water bowl which has a 2.5" hole in the center and the PVC pipe is 1.5". What is the best way to seal that? I googled this for a while but couldn't find a good solution. The only thing I found is a seal kit from slick rock for their bowls but that is too small to seal a 2.5" hole.

You could likely use a bulkhead fitting (upside down - glue the 1.5 slip on the 1.5 pipe from below then set the bowl on the neck and tighten from above) like these:

Doing a quick search it appears many people just run the pipe thru the hole, cap it with a tee to prevent the bubbler effect, then fill the hole with hydraulic cement
Hydraulic cement is most commonly used and sanding of the pipe that will be in contact with the cement will help with adhesion of the two.
I kind of like the bulkhead option better but unfortunately it looks like it wouldn't cover the 2.5" hole. When going with hydraulic cement does it stay in place even with kids holding on to the bowl or will it crack easily?

The bulkhead I linked said it required a 2.375" hole so it should cover? It's amazon so no harm in trying
Just saw that. I will give that a try. Just trying to find a bulkhead which is slip on at the bottom and threads on the top so I can screw in a bubbler insert.

JT Bulkhead Fittings (1-1/2" FPT x Slip) https://a.co/d/9gYruUF
Looks like they have fpt x slip and slip x fpt ...but can't tell which is which lol
This is a bit easier to understand Lifegard Aquatics Slip Bulkhead (Flange) X FPT (Bottom Side) I guess that one should fit my needs. Let's see once they arrive. @Ahultin thank you so much for your help.
