hi.todd & wet_boots,
I capped one of the 4 Rain Bird
5000 heads and the pressure increased to 30 psi. I am now going to replace all
four nozzles in the zone. They are the original 3.0, do you have any
recommendations for replacement nozzles. Perhaps I should try 2.0 rain curtain
nozzles?

Spray heads operate at 30 psi and spray less than 15 ft.

you may have to reduce your gallons per minute to increase your pressure.

Good Luck.

:thumbsup:

23 psi is showing at the "head" not at pump discharge! With zone and head operating

23 psi won't run anything that will spray 35 feet - you got work to do - if this 23 psi is showing at the pump, then you got real problems

Wet_Boots I just checked the pressure of that zone with the 4 heads running and it's 23 lbs. Is this adequate?

RE: pressure

Correction, Sorry that is a 1 HP pump!

Quoted from "fenwood 5000"

Wet_Boots I'm going to check the pressure @ head which is supplied from a well by a 2 HP
pump with 4 Rain Bird 5000 heads 3/4" IPS inlets on this zone! I'll get back to you with the reading

Sight unseen, your system does not have the pressure that is needed for a single head to cover every bit of its 'territory' ~ modern design practice is to space sprinklers head to head, so that at least one other sprinkler makes up for any other sprinkler head's shortcomings.

The solutions have already been given - change every head nozzle in the zone to a size smaller - now the zone consumes less water, and the heads will have higher pressure, and higher pressure can improve the close-in coverage of heads.

The 42SA is the same thing as a 5000 - just a different label

The clumsy old Maxipaw impact head is a throwback to times when head to head layouts were uncommon - all its moving parts splash enough water around to give it superior close-in coverage - a Maxipaw can give better low-pressure performance than any gear-driven rotor like a 5000

If I could achieve ( Distribution Uniformity) @35' it would be good but the 5000 shoots right over the closer in grass and hits the shrubs @ 35' but misses the closer in grass perhaps the 42SA might work better?

That rain bird nozzle is a pretty even DU ( Distribution Uniformity) . It's actually designed to work just fine fully open and shoot 35'. However, that is in conjunction with a properly designed system with overlap ( Head to head coverage) .. If the design is off then yes there will be coverage issues.
