A: Good day, This product is not UV rated or good for usage on a non interference pipe fit. Thank you,
A: 1.5" PVC yes.
A: I am unsure since I used it on PVC
A: I personally would not because this a very "hot" glue which sets up fast and if some gets inside the pipe and got on the wiring inside, it may eat thru the insulation. Home Depot sells this - Oatey 8 oz. Medium Gray Electrical PVC Pipe Cement - it works great and is only $5.74 a bottle. It worked great for me ,easy set and it did not take much per joint.
A: No only plumbing pvc
A: Yes it can.
A: Yes but don't use gray conduit for water.
A: Yes a primer should always be used.
