This is another sprinkler question
 
My friend has a Hunter Pro C system.
He asked me to look at it because it has one valve not turning off?
I think this is where the trouble lies, We can unplug the electric from the box, turn on the water and the one zone will come on and not stop unless He turns the main water feed line off.
The best that Ican figure is one the valves Solenoid went bad?
or two, a chunk of something won't let the valve close off?

Can I buy and replace this solenoid with ease?
If I wanted to try and clean the valve and return the cover, is this an easy task ? Like a gasket or a secret trick I should know about.
If I need a new solenoid where can I order one In Michigan.
If I do need a new solenoid, will the old one have a part number on it ?

You either have a piece of debris stuck inside of the valve or the solenoid is loose. The solenoid on some models can be used to manually turn on the valve by rotating it counter clockwise, usually a quarter of a turn. Slightly tighten it to see if it corrects the issue before tearing the valve apart. Also check if there is a "bleed screw" on the valve, will look like a plastic + on the body of the valve and if open water will be actively leaking when the water is on.

Here is a common Hunter residental valve cut sheet http://www.hunterindustries.com/Reso...ic/LIT224w.PDF

To tear apart a valve

Turn off the water @ the shut off

Depending on the model of valve, you will have 4-6 screws (phillips usually) holding the bonett down on the body. Un screw them and be carefull not to lose them. Water will gush into the hole and most likely drain for a few.

Pull the bonett up with one hand while the other slides under to catch the spring (if not attached and the diaphragm).

Sweep your finger in the body of the valve carefully and feel for any debris, often times the debris will flush out as you are raising the bonett.

Check the diaphragm for any damage, hold it up to the sun or a light and see if there are any punctures or slits. If there are you will need to replace it.

If all is ok replace the components in the order that you took them out. Take care to not over tighten the screws, they only need to be hand tight. And make a mental note of how the bonett came off the valve, ie in what position was the solenoid in relation to the screws so that you align it correctly.

It may take a couple of tries but its not rocket science.

Good luck
