We’re replacing a stretch of cast iron pipe with PVC. This stretch of new PVC pipe will connect with the main, which is concrete.
However, connecting them seems to be tricky; the concrete pipe entrance is 4 inches on the inside but 8 inches on the outside.
I’d like to know if it would be advisable to use a reducer on the concrete pipe, so that we can connect the 4inch PVC pipe to the main.
Here’s photos of the existing concrete entrance to the main and the product I was thinking of getting to connect the new PVC.
Also, if getting the reducer is an option, is there some sort of sealant I should also use to bond the PVC fitting with the concrete? Any other tips? Or is this a bad idea?
