I am building an irrigation system. The instructions that came with the Orbit manifold say use PVC cement. Watching videos like below I see this PVC glued with or without primer.
Here is the PVC pipe that I have.
So what glue do I use and do I need primer or not?
Grrr here is a study showing that priming does not help at all, on the contrary.
So what are they selling us in the stores? This looks like a scientific study to me, tests, data etc., so it is not story based but real hard fact-based.
