PAUL MANLEY
I have an inground swimming pool that is plumbed entirely with schedule 40 PVC (think above-gound and under-ground through concrete).
I installed a new 1.5 hp pool pump and the threads on the exiting 2′ male PVC connecter have failed twice. Being a novice I assume the threads are failing because the water pressure is greater than what the threads were made for.
I would like to use a 2″ Male copper connecter and attach it to the existing schedule 40 PVC. What is the preferred method to do so?

What thread sealing material are you using on the threads to make them watertight?

Threaded adapters are for adapting un-threaded pipe to a threaded connection of the same material. Like a PVC pipe into a PVC filter housing that has threaded connections.
To connect metal pipe to plastic pipe you need to use a special fitting designed for the job that can handle the different expansion rates and maintain a seal.
