King Innovation 45055 Leak-B-Gone pvc ring, White

Is 2,5" pipe availible?

couldn't someone just cut the end edge off a piece of pipe and then cut it into two half circles and do almost the same thing?

Do the leak-b-gone kits come with the primer and cement?

>Will this work for a leak where the outlet pipe of a pool pump joins with the pvc pipe that takes the pool water to the sand filter?
