Pump and psi confusion

If you can, turn "off" half of the VAN nozzles and see what the others do.

I've seen a whole zone of VANs @ 180* each where they all leaked some around the seals (10 yrs old). They all sprayed but not well. After replacing them all, pressure and performance was just fine.

Could also be that the valve for that particular zone is faulty and not opening all the way. Could also be a partial blockage in the zone.

Zone 1- (6) Pro sprays with VAN's operating at 15 psi. This zone will not pop up, I suspect due to the low pressure.

Zone 2 and 3- (3) I-20's operating at 25 psi, appear to operate correctly.

Zone 4- (6) Pro sprays with VANs operating at 10 psi. Again, this zone will not pop up.

Zone 5- (3) Pro sprays with 25 psi no problems noted.

Thanks to all who posted. I changed out the VAN's to 10' fixed sprays and fixed the pressure problems. Zone 1 when from 15 psi to 40 psi and Zone 4 went from 10 to 37 psi. All appears to work correctly. It is amazing how much pressure the VANS eat up.

What, you think a new thread costs money?

Can I pay that in installments?

Pumps do what they do unless there is a problem with them.
Pump impellers wear out.
Pumps sometimes have low voltage to them due to electrical issues.
Pump intakes can have air leaks and/or clogged foot valves.
The pump curve chart, along with the depth to the intake, would be the first things that I would look at.
Well, that and looking to see if some doofus installed all VAN nozzles.
