Sprinkler valves are usually found in the sprinkler manifolds in your system. These are about often constitute in the green boxes cached effectually your one thousand. Within these boxes, you lot'll meet an array of pipes and fittings with niggling black valves. On those black valves, you lot should see a cylinder rising out of the top of each valve, and wires running out of the cylinder. This black valve with the blackness cylinder is the electrically automated sprinkler valve. Complicated equally they may seem, information technology's usually non hard to observe -and fix- the problem.

Diagnosing the Trouble:

There can be a few giveaways that a trouble is almost certainly your sprinkler valve. This includes:

Sprinkler Zone non turning on consistently
Sprinkler Zone not turning off
Water leaking through sprinklers after zone is off
Sprinkler not turning on at all

If yous look in the valve box, at that place's a few things yous can look for to easily find a few problems.

Audit the Sprinkler Valve

First, await for any leaks. If at that place's water in the valve box, particularly if the sprinkler zone hasn't been run in a while, this could mean either in that location'south a crack in the sprinkler valve, or in the pipes immediately around the valves. Endeavour turning off your main water shut-off valve for the sprinkler system, and let the box drain out. When the box is generally drained, inspect each sprinkler valve and all the pipes. Look for cracks or punctures in all the plastics. Carefully make sure that all of the fittings are tightly secured as well, equally these can loosen and leak h2o, causing pressure bug. While y'all're hither, make sure the bleeder spiral, pictured below, is tightened all the way.

If you lot oasis't found any visible cracks or leaks, try turning the water back on, and going back to the box. Listen and picket for water drops. If you lot can encounter any water dripping out of a piping, brand notation of where, and plow off the organisation once again to make repairs.

Finding problems by Actuating the Valve

If you still haven't institute any issues, nosotros'll movement on to actuating the valve itself. This is a adept time to grab someone to assist, if you haven't already.

First, take the flow control, that's the screw in the moving-picture show below (not all valves take this, and then if yours doesn't, skip this step). All you're going to exercise is tighten this all the way clockwise, then loosen it all the manner counterclockwise. Repeat this a few times. This tin can help piece of work dirt and debris loose from the diaphragm inside. When yous've loosened and tightened fully, loosen it all the manner counterclockwise and nosotros'll motility on to the side by side step.

Now, put your paw on the solenoid. That's the black cylinder poking out of the top. Rotate this nigh a quarter plow counterclockwise. This should activate the sprinkler valve, and let water to pass through freely. If information technology does, tighten the solenoid over again. This should turn off the sprinkler zone again. Put your mitt on the valve, and listen. If you feel or hear water trickling through the valve when the solenoid is screwed all the fashion in, and the bleeder screw is tightened all the fashion, it might be fourth dimension to rebuild or replace the automatic valve.

If the sprinkler has worked perfectly through the tests thus far, it's probable an upshot with a sprinkler timer or wiring. These tests should accept establish a trouble with your automated valve, if there was ane. Yous tin can still proceed to the repair section of this commodity to make clean the valve, but the valve itself is probably not the issue.

Equally you remove pieces from the sprinkler valve, clean each slice, and go on them in a clean place while you finish cleaning and reassembling the valve. Be careful to recall exactly where each slice of the valve goes.

Here are the steps to disassemble a sprinkler valve. At that place is a gallery of images beneath for reference. Clean each role with water until visibly clean and to the bear upon.

Remove the Sprinkler solenoid (Not necessary to clean this function, unless in that location is a big amount of droppings on it.)
Have the screws out of the meridian of the housing
Advisedly pry the top of the housing away
Remove the spring from the sprinkler diaphragm
Carefully remove the condom diaphragm from the housing
Clean each part, especially the surfaces between the diaphragm and the housing
