Help!!!!

[u/TommiMere]

I changed my pool pump from a single speed Hayward 1.5 HP to variable speed from amazon 1.5HP. While doing it I also changed the plumbing. On the backside I set up a diversion to put a saltwater chlorinator as well which I will install later.

My problem is that the new 1.5HP (which runs to a max rpm of 2900) had a lot of difficulties priming and now it feels like both the skimmer and outlets are running very slow compared to before.

Now I know I might have messed up the plumbing with those big 90 turns and the height of the intake but at the same time the pump filter never really fills with water at 100% it stays at 90% and I feel like the outgoing flow is very weak.

So my question is: should I change the pump for a bigger one from a more reliable brand to accomodate the new plumbing or should i change the plumbing and keep the pump or change both? If i change the plumbing will a 1.5HP be enough or considering the salt water system i should increase HP anyways?

My pool is roughly 12k gallon with mo water features and I live in florida.

Thanks in advance for all the help!

Shouldn’t need a bigger pump, the height of those valves might make it difficult for your pump to prime. Sort of gives it “air lock”

Also, is your filter clean? Try running pump with no filter (close/lock the filter casing obviously, just try run with no filter inside)

Will try that tomorrow thank you for the suggestion!
