Hi Doc,

I appreciate it a lot for you to take the time to review my pool equipment.

The pool came with the house we purchased a year ago. I would have never given it any thought that there's a potential pump/motor mismatch. Motor seems to run very hot (when water hits it vaporizes).

Here some pictures of the pump label, motor label (I am pretty sure it says 2.0 HP) and general setup.

Looks like your Amazon links are a bit mixed up.

The 3/4 HP Impeller shows the seal kit.
The 3/4 HP diffuser shows a 1/2 HP Impeller
The Seal kit shows the diffuser.

I almost think it's easier to install the long term fix as installing the ball valve seems to be a big challenge with the current routing of the pipes. Enabling the slide reduces the pressure by 5 points.

Thanks,
Ernst
