New pump now lower pressure

I have a 25,000 gl. pool. The 1 HP Hayward Superpump just burnt and I replaced it with a brand new Hayward 1 HP pump. The old pump psi was 30-40 and the new pump psi is less than 10. I can't figure out what could be the problem. There are a couple of leaks that need to be fixed but they were there with the old pump, as well.

Welcome to tfp, pelinkovicci :wave:

What is the model of you new pump? What kind of filter are you using?

30 psi is really high filter pressure, 10 is in a much better range. Are you sure that you gauge is working? Does the gauge go to 0 when you turn off the pump.

What kind of flow are you getting at the pool return?

That is a psi gauge issue. You either replaced a broken gauge or dislodged something in the old gauge.

You would have had 0 flow with a true psi of 30-40
