While I have done basic PVC plumbing in the past, I need a little help with some pool plumbing. I have purchased a new Pentair Intelliflo VS pump and will be replacing an old Pentair Challenger Single-Speed. My concern is about how to go about plumbing the inlet to the new pump, since there is currently not much to work with. Here's a pic:
So I have two issues:
1. The inlet on the new pump is two inches lower than the pipe. Not really a big deal as i figure I can get some good concrete pad/block to raise up the height of the pump. Anything wrong with this?
2. The new pump requires a run-in length of at least 10 inches. In the photo you can see that the union is butted right up against the valve, so not sure how I would undo this without destroying the valve, etc. I haven't tried to disassemble any of this yet, but after unhooking the union and removing the pump, I estimate I will be left with half a union stuck in the valve with no place to cut.
