How much PSI?

I "inherited" a sprinkler system, it is a well system with a pump.

The back yard has 4 of the Rain Bird pop up impact sprinklers and one impact on a riser.

When the back yard zone is on, the gauge on the pump is at 50psi.

Is there any way to find out the total PSI?

What are you trying to figure out here?

Your pump is running at Dynamic 50 PSI when the back yard zone is on.
You don't need to know the static.. because that would burn up the pump

Check the model on your pump and google it up..

It should give you the info what your looking for

for example 1HP 1.5" outlet/inlet 35 gpm max at 60 psi

Thanks.

I need to add a couple sprinklers to the back to cover some spots.

Also, I want to add two zones that will cover the sides and the front yards. I would like to know that I am not putting more sprinklers than the pump can handle.

Use the existing zones as a guide to what the well can deliver.
