A lawn watering system in your residential property is only effective if each sprinkler valving is functioning correctly. As a matter of fact, sprinkler valves can result to breakdown or failure when your lawn mower runs over the sprinkler heads or lash them with your weed slicer. The following are some guidelines on how to fix a sprinkler valve to prevent future issues or headaches:
1. Inspect Your Sprinkler Heads for any Damage
If your sprinkler head is scraped, dented or slogged, the sprinkler valve inside it might be out of commission.
2. Shut Off Your Water Supply and Sprinkler System
Turn off your sprinkler system controller prior to starting any repair so that it can’t initiate a watering program. Prior to disassembling the sprinkler head, shut off first your water supply. You can be injured when you try to let go of the valve while it’s under pressure.
3. Get Rid of the Solenoid
Release your sprinkler valve solenoid from the sprinkler head through unscrewing it clockwise. A plunger is situated close to the solenoid. See to it that the plunger can retract and release freely and properly.
4. Unscrew the Top Portion of Your Sprinkler Valve Housing
The sprinkler valve housing will either possess a jar-type top with grooves or a bonnet top joined together with 2 or more screws which should be twisted to release. Then, open the top portion to remove the spring and flexible diaphragm in your sprinkler valve. This flexible diaphragm can be wedged into the jar top or bonnet or in the body of your valve housing. Check how the spring and diaphragm are located so that you can assemble them again properly.
5. Check the Spring and Diaphragm
Examine for any holes, rips or tears in the diaphragm as well as check the spring to see if it has no dents, warped sections, nicks or scrapes. Gently squeeze the spring between your fingers and then release it. Basically, the tension should be released instantly. In order to get rid of the debris or dust, rinse off the diaphragm using fresh water. If either the spring or diaphragm is damaged or broken, replaced them with new ones. You can contact a professional to repair a Broken Sprinkler System.
6. Check and Clean
Clean every valve housing, getting rid of the sand, mud, and any grass or leaf residue. Inspect up to the inside portion of the jar top or bonnet to see if there’s any grooves or nicks. In addition to that, check the two ports of the valve housing and get rid of all the hindrances with the use of a thin wire.
7. Change any Damaged Parts with New Ones and Reassemble Your Sprinkler Valve
Once you locate and replace the damaged part, put back together the sprinkler valve as it was. Thoroughly tighten the screws in your jar top lip or bonnet and then reinsert the mechanisms of the valve firmly into the sprinkler valve head.
8. Restore Your Water Supply and Test the Performance of Your Repair
Reopen your water supply to your sprinkler system and reactivate the controller. Lastly, test the outcomes of the repaired heads in your sprinkler system.
