I'm replacing my old Whisperflo with a new 2-speed Whisperflo. I've never done any PVC work on the pool before, so I could use some guidance.
1) The old pump is glued in on both connections. How should I install the new pump? This video shows him using a threaded end on the inlet, a fitting extender and a union to a high temp pipe for the outlet. Is this the way to go?
2) Can I tell what diameter piping I have without cutting off the motor first?
3) He uses something called "joint stick" on the threaded fittings into the motor. Is this recommended?
4) He uses "pool heavy" for the pvc cleaner/glue. Is this recommended?
5) Any other tips?
Here's my setup:
