I’m using this coupling for some flexibility in long runs of schedule 40 PVC pipe. Should I use PVC glue at this coupling? It’s going to be under a concrete patio so I want this tight and leak proof. Assuming it’s OK to use this under a patio pour with schedule 40!
@@DragonBuilds Glad to hear it. Fernco's pdf instruction for their donut say: "Lubricate the outside of the Donut with a soap solution" so that should also do.
