water pressure to low? options?

Thanks for taking a sec to at least look.

My yard is 25x30(with a 5'x7' corner cutout). I have eleven Rainbird 4" 1800 series popups with HE-VAN-15s. Five 90* Four 180* and two 360*. The pipe is 1/2" and is plumbed to rap around the perimeter with a cross pipe cutting the rectangle in half the long way. 25'x2 30'x3.

Depending on the time of day, and I assume the water usage in the neighborhood, there are 2-3 sprinklers that do not pop up or only pop up part way.

Do I have too many sprinklers? Should I switch to HE-VAN-12s? Should I get some of Rainbird's PCS filter things and drop the output?

I'd like to avoid splitting it into two zones,...

Thanks again.

First of all the 1/2" pipe was a bad idea.

Check to see if the seals on the sprinklers are bad. Leaking profusely.

Measure how far apart the sprinklers are. The less distance the less water used. You need head to head coverage only. No need to overspray.

I've had really good luck with the Toro Precision Nozzles I believe they use 40% less water. That might fix you up. Of course you have to run them longer to get the same amount of precipitation.

Those are great nozzles.

I am so happy to hear somebody else has appreciated them too.

They should be called bacon savers as they can save your bacon on repair calls.
