How do I find the fault in my sprinkler system?
mike e asked:
I recently bought a new home. The sprinkler system works great, except one zone. In that zone, the sprinklers don’t turn on. I can hear the water initially start to go into the line, but no water comes out of the sprinkler heads. I don’t want to dig up my entire yard trying to find a hole in the line. Are there any good ways that I can find out where the leak is at?

I have already tried letting it run for about 6 hours to see if there is any swelling in the yard and nothing shows. So any other ideas?

I would first try going to the sprinkler valve and turning the solinoid 1/8 turn to loosen it this will manualy turn on the valve if you do not get any water out of the system then it could be a clog in the line or a bad valve. To see if you have a clog remove the sprinkler head from the first in sequence and turn the system on, this will also let you know if there is any water going through the system

first crack the line below the valve to see if the valve is opening if not replace it second take the fartest head off turn on the system if the valve is working and see if the line is blocked with sand if not check the heads they may be bolcked

Open nasal in top of sprinklers one by one if water from each section come out ,change nasals and if water did not come out pipe is broken in that branch and you must immediately fix that problem .

first off, test the water meter.
1. see how fast it spins when you turn on your bad zone, and see how fast it spins with a good, working zone. If it does slower, or no where near as fast on the bad zone, than you have a bad valve, or a solenoid on the valve.
if it spins the same speed as your good ones, than you have a leak somewhere preventing all the water pressure.
but if you have run it for 6hrs and not found it ill bet its a valve.
you will not be able to fix it if its a valve, unless you know where there at.
you will need someone with a wire locator to find them if you dont know where the green boxes are.
if you do know where it is, than you can try to change the solenoid first, and if it still doesnt work, rebuild the valve.
