Dial back on the theory....no need to replace 90's with sweep 90's.
There is no way you need a fourth pump.

Thanks for the advice. I'm not sure what a '90' is but the pool was
built in 2001 and it's complicated. Too complicated. It's certainly
not KISS.

btw * 5' of head is about 2 psi..... not a lot pressure.

Interesting. If it were me, I would have put the pumps at the same
level as the pool deck.

Then, you would have to worry about priming them.

Most will self prime that far. *If not, a little water in the pump basket is
enough. *If there aren't any leaks the pump will stay primed.- Hide quoted text -

Yep, the pool pumps I've worked with have all
been above the water level of the pool, typically
on flat ground with the water level a foot or so
lower and they self-prime.
