I hate to agree with boots
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.
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.
Ooops. meant to start a new thread. My bad.
What, you think a new thread costs money?
Can I pay that in installments?
Well spoken, kemosabe
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.
mp conversion and burn that motor out.
