Re: Hayward Pump questions
My main point in addressing the pressure issue is that you would be better off energy wise with the 3/4 HP pump as long as you can get it to work properly. If you can move the VRV, you may not need to have the washers in the return in order to use a 3/4 HP. This will also improve the efficiency of the setup.
The VRV can be installed almost anywhere down to a few feet above the pad but on the supply side only. Some installers will put it a few feet above the pad so it is easily accessable for replacement. This works well for two speed pumps on low speed but is not recommended for very hot climates where the water can sit in the panels and heat up enough to soften PVC.

Nope, no leaks around the pump.

Here's a depiction of my setup (VRV at the top left):

Do you think if I put the VRV at the bottom right of the panels it may take care of the air issue?
Re: Hayward Pump questions
It looks like you only need about 2 PSI more to close the valve so given the height difference and the fact that you are not going through the panels, there is a good chance that it may work.
If the VRV is the kind that fits in the end of the panel header, then it would be simple to check.
Re: Hayward Pump questions
Thanks. I'm certainly going to give it a shot!

Obviously, the receptacle's convenient as I store the pump away for winter.
I also have my Super Pump wired to a standard 3 prong grounded plug. My pump DID NOT come this way, I had to take it to a motor repair shop to have it done when the electric in my yard stopped working. My understanding is that Super Pumps always come WITHOUT the three prong grounded plug, so you may have to go to a shop to have this added.
