7 Rainbird 5000 not covering

[weed wacker 2]

Im not an expert on irrigation but I am slowly learning. I have a property where 7 Rainbird 500s are only covering 22ft. They are 8ft short of what they need to cover. Im not sure what the problem is. I don't know if its pressure related or what. The system is 4 years old.

Have they ever worked properly?
Could be low pressure, clogged filter, nozzles too large, or possibly 10 other things.

Yeah I know there is several different things that could factor in. Im not sure if they have worked properly before because we havent been taking care of the property long. Also in the controller box, the wire to the zone 14 is not even connected in the box. I couldnt even find the wire a wire that goes there. The #4 was unhooked also. I hooked it up and its working properly.

Sounds like you have a low flow situation. Does the system have a pump or is it city water. If you can measure the supply, then you will know if you have enough flow to power 7 heads. What size nozzles do the heads have. If they all have 2.0 Gallon per minute (GPM) nozzles the you'll need 14 GPM from your supply to pressure them up.

Im not sure what the nozzle size is. I will check. Ill hook a flow meter up and check the flow. Its on city water. any ideas about the wire. The sleeve goes underneath a parking lot so it would be difficult running a new wire. Can I use a wire locator and attach it to the wire on the valve and see where it stops at heading to the controller.

Don't take this the wrong way.....

How can you be contracted to maintain the property if you have no irrigation skills or knowledge?

The questions you are asking a pretty basic issues and I am guessing you are doing the lawn care including the irrigation services?

[weed wacker 2]

Yes we do the lawn care on the property. I've replaced heads and broken pipes before as well as backflow repairs but I have problems diagnosing some problems. I'm on here asking questions because it's what you do when you don't know the answer.

Like someone posted, could be many things. Are all of these on the same station?

Need more info to help you.

No they are two different stations. One with sprays and the other with rotors.

Do not mix sprays and rotors.

How many rotors on a station? How big is the meter, Main line and valve?
