The best overall pick—the Orbit Anti-Siphon Valve—is a quality choice for the vital job of protecting the home’s drinking water by preventing water from the sprinkler system from flowing into the home’s water supply pipes.
Correspondingly, How do you test a hunter solenoid valve? 
How do I choose an irrigation valve? When selecting sprinkler valves, you’ll need to consider a few important factors: Flow rate: 3/4-inch valves work best in systems where flow rates are roughly eight to 10 gallons per minute (gpm). For faster flow rates, choose larger valves. Climate: In colder climates, anti-siphon valves will require winterizing.
Furthermore, How do I know what size sprinkler valve I need?
Are brass sprinkler valves better?
Higher Chemical Resistance — Brass is more resistant to chemicals typically found in irrigation water and therefore less susceptible to failure due to cracking. Longer Life — Brass valves can be used above and below grade whereas plastic degrades over time in extreme environments and in direct sunlight.
How do you repair a hunter valve? 
How do you turn off a Hunter valve? 
How do I know if my solenoid valve is working? Sometimes you find a normal read on the digital multimeter but the coil is actually not functioning. At this time, you can use a screwdriver and put it near the armature then energize the solenoids. If there is a magnet in the presence, the coil is good. Otherwise, it is bad, and you need to change a new one.
Where should sprinkler valves be placed?
In newer lawn irrigation systems, the valves should be installed in valve boxes set into the earth. Often these are easily visible. In small yards, there is often a single valve box located near where the irrigation pipes enter the ground from the water source.
How do you size an irrigation valve? Lateral Line
- Draw a line connecting all of the sprinkler heads in each separate zone. …
- Draw a line from the sprinkler line to the zone valve. …
- Begin sizing the pipe. …
- Add the GPM requirements of those two heads together to size the next pipe.
- Add the GPM requirements of the next head to the previous total.
What are the three types of main sprinkler valves?
There are three basic types of valves used in irrigation systems – gate valves, ball valves, and electric valves.
How do you fix a leaking sprinkler valve? 
How long do brass sprinkler valves last?
In general, a sprinkler valve will last about 15 years.
Are brass check valves better than PVC?
Brass is more expensive than PVC and can resist corrosion better than plastic valves. It can withstand more heat than plastic, making brass valves an optimal choice for home plumbing systems.
What causes a sprinkler valve to stay on? One of the most common reasons for a valve to keep running continuously is the accumulation of debris in the diaphragm, which prevents the valve from closing. This video will teach you how to clean the diaphragm on your valve. The most common reason for a valve to remain on, or weep, is debris.
How do you install a hunter valve? 
How do you clean a hunter solenoid valve?
Why is my Hunter irrigation system not working? The most common reason your sprinklers are not watering is because the rain sensor is active. Do you have a rain sensor on your sprinkler system? If so, slide your sensor bypass switch into the « BYPASS » position (on an SRC, turn the dial into the RUN (Bypass Sensor position).
How do you open a solenoid valve manually?
What is the 5 five common problems for solenoid? Reasons for faults vary depending on the type of solenoid valve and application. It can be an under or over-voltage, wrong valve capacity, impurities in the media, pressure drop, wrong material, or just bad installation.
What causes solenoid valve failure?
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.
When should a solenoid valve be replaced? As a general rule of thumb, if your solenoid valve show signs of wear or damage, then it is likely time for a replacement.
