We are putting a new pool in and I've been watching the construction process very carefully. All of the pipes that are underground and around the equipment pad use primer and glue. Today a worker was out putting in the spa fittings and pool fittings. I asked him why he wasn't using primer but was instead just using a gray glue on the schedule 40 PVC, he said that if the primer gets into the threads that it makes screwing in the fixtures difficult. I have no idea if this is correct or not, what do you experts think?
The good news at least is that if I do have a problem that the fixtures can be reached and dealt with, we might have to dig into the pebble sheen a little bit but at least we wouldn't have to blow up the concrete.
Thanks in advance for your advice.
