Rain Bird valvesare the controls responsible for controlling the current of water to parts of or the total sprinkler system . Most sprinkler system have two types of valves . The first , the gate or chunk valve , is used as the shutoff valve for cut off the intact system . The second is the zone valve , which is used to shut off sections of the system . Manual or electronic signals tell the Rain Bird valve to open or close , twist on or off the water system . Sometimes valve will not turn off , causing water to continue to leak out or run .
Controller
Step 1
Incorrectly set controllers are one of the most common reasons that Rain Bird valve will not turn over off . Valves are group into sections called zones . seldom should more than one zone operate at once . If more than one zone is running at the same metre , check the sprinkler comptroller to see if the zones have been circumstantially programmed to pass at the same fourth dimension . Solve the problem by changing the episode of the zones or the timing on the restrainer to prevent the valves from being on at the same time . Instructions for operating the controller are by and large located on the privileged panel hat of the box .
Debris
Rain Bird valve are located in the footing where grease , rocks and loose debris can get into the solenoid of the valve and cause it to become stuck open , allowing cover flow or leak . situate on the top of the valve , the solenoid is controlled by electrical wires from the controller that send signals to give or close down the valve . When dust get in the way , the solenoid does not work aright . Take off the solenoid covering and take away the solenoid plunger and filter . Rinse with clean water supply and re - install . jibe the system to determine if the valves are now operating correctly .
Loose or Open Solenoid
The solenoid also playact as a manual control for opening the valve manually , bypassing the comptroller . This is useful when draining the system for the winter or other outcome , such as preforming upkeep on a section of the system of rules . If your valve is still operating when it should be off , pervert the solenoid in a clockwise way to fold . This same motion will also sour to tighten the solenoid if it is loose .
Parts
Valves have working parts that have on out , become damage or are lose . Simple things , such as the solenoid O - ring , plunger assembly or servant , can get the valve not to turn off when damage , missing or worn out . Occasionally part can also become misaligned and not varnish right because of debris . If the valve is continuing to ply after eliminating other potential causes , wrick off the piddle and check operating parts for result . A discredited or bent solenoid O - anchor ring is often one of the most common problems , easy fixed by scrutinise and re - install or supercede it aright if it is twisted or damaged . If debris is causing misalignment , clean the affected parts and re - instal into the correct attitude . start the arrangement again to make certain everything is operating properly .
