Automatic Drain Valves

  1. Turn off the water supply by closing the main valve to the sprinkler system. As pressure inside the system falls, it will drain water automatically.
  2. Open the drain cap between the main valve and the backflow device.
  3. Lift each sprinkler head to drain out any residual water.

Can a sprinkler system leak when off?

Each valve in your sprinkler is like a faucet, which shuts off and turns on water flow. You can spot leaky valves easily because water will continue flowing out of the sprinkler long after you’ve shut it off. However, this type of leak could also be an indication of low-head drainage.

Do you need a backflow preventer on sprinkler system?

The key to preventing backflow is to have a properly installed, maintained, and inspected backflow prevention device as part of your culinary water system. The answer is: you need backflow prevention if you have a culinary water connection that may be used to supply a sprinkler system.

  3. Water Leaks. There are many points in a sprinkler system that can leak.
  4. Current Testing.
  5. Valve Inspection.
  6. Parts Replacement.

Can a sprinkler solenoid get wet?

Sprinkler valves can be fully submerged in water. However, the valve should not be kept permanently in water, as the screws will rust faster. You should also make sure the electrical wires have waterproof insulation and that the valve will not freeze.

What causes a sprinkler valve to leak?

The most common reason leaks occur is that the rubber parts in the valve box have worn out. Water seeps freely through the system when the diaphragm seal breaks or debris is obstructing the valve from closing. A broken or aging sprinkler valve diaphragm seal only gets worse over time.

How do I manually test my sprinkler system?

From the Timer Box

  1. Turn the dial to the “Auto” position and press the “Manual” key to test the valves on Easy Dial and Easy Set Orbit timers.

Why do my sprinklers stay on?

More often than not, there will be a valve that is stuck in the “open” position on the pressurized system. When the valve remains open, water continues to run down the line, which causes your sprinkler to continuously run even when the timer is in the “off” position.

How do I know if my sprinklers are self draining?

What is a self draining sprinkler system?

The self draining valves drain slow so there isn’t much extra water used. They also claim the tubing they use can expand 14% and water expands 6% when it freezes, so even if the system isn’t fully drained it won’t be damaged if it freezes.
