The way to Replace a Sprinkler Control Valve
If you have several separate garden areas in your lawn, like a vegetable garden surrounded by a large lawn, your sprinkler system typically includes valves to control the different watering needs for each planted space. By way of instance, your bud needs much more water than a frequent flowerbed. But corrosion and weathering can cause among these valves to fail entirely. Replacing the valve needs some detective work to find the neglected component while preventing water from escaping the irrigation system.
Turn off your water source.
Activate a good valve zone on your irrigation control panel. Permit the water to run through the system to alleviate extra pressure.
Turn your irrigation system away at the panel.
Practice your irrigation wiring in the control panel outside to the garden area. Press a soil probe into the ground to find the valve box. Avoid damaging the underground wires; they direct you to each valve place, if your system is equipped with multiple valve installations.
Eliminate the soil covering the valve box using a scoop. Lift the lid in the valve box and then set aside.
Put a hand pump close to the valve box. This pump removes water in the box if a large amount escapes during removal.
Eliminate the threaded valve in the piping by means of a wrench. Activate the hand pump to eliminate any water in the box as you detach the valve.
Attach a new valve on the piping using the wrench. Notice the orientation of this solenoid extension on the valve. It ought to be in the exact same place as the older valve to direct the irrigation water properly.
Put the lid back on the valve box. Expand the soil back onto the valve box using the shovel.
Turn your water supply back on. Activate the irrigation system at the control panel.
Test the new valve by triggering that area with the control panel.
