Low pressure at sprinkler heads.?
Question:I am trying to install a residential sprinkler system. Most of the system works fine with sufficient pressure. However, the further zones with rotary heads basically trickle. I measured the pump output to be 5 GPM, is this my problem. I even tried a pressure tank which made little difference. I can also hear a gurgle of water at the valve for the furthest section. I used 1 inch piping. What can I do?
Answers:
Either you have heads that require too much water per head or you may have a problem with the piping. I almost sounds like you may have a broken pipe.
To test this cap the pipe on the supply side, remove the heads and test at one of the head with an adapter and reservoir. If it holds water then concentrate your efforts on the heads themselves.
Try putting fewer heads on each valve.
hi
you need bigger pipe at the beginning and work your way to small pipe.
also there should be a screw on top of the pringler head to adjust to used less water.
5mpg per minutes is not much for running springler on a lonfg distance.
city water pres. is about 40 to 50 psi and that work fine but you nedd to split your pringler to word in group not all together
You have a leak somewhere between the valve and the zone, Maybe at the valve itself. Three heads on one zone should run well ok even with low pressure. I would suspect a leak after the valve because you'd have a flood if it was on the pressure side. Also the head's nozzles may be missing or too big.
