Attached is my current set up. The plan is to replace a single-speed pump (Hayward TrisStar SP3207Z1BE) with a VS pump (Hayward TriStar SP3202VSP). One of the reasons I chose this pump was because I was advised that swapping one Tristar with another is an easy DIY task. I thought I could just unscrew the joints, but everything appears to be glued in. Will I have to cut the 1 1/2" PVC pipe and get new 1 1/2" to 2" converters or will I be able to use the joints from the previous pump? I am trying to avoid dealing with cutting PVC as I have no experience with it and have no idea how complicated it would be.
