After you’ve checked the integrity of your system’s components and have ensured that Mother Nature has indeed agreed to let Spring stay, these are the next steps to follow for sprinkler start up:
Water Hammer Warning! When the water valve is first opened, it causes a high-pressure surge of water into the system. This is referred to as “water hammer,” because the force of the surge can cause major damage, including burst pipes and broken valves. The key to eliminating water hammer is to open the valve SLOWLY and gradually introduce water into the system.
Control Pressure: Do you have a water pressure gauge on your faucet? If not, you should consider purchasing one. A pressure gauge allows you to monitor the water pressure to make certain it does not exceed the limits of your sprinkler system. Too much pressure may cause damage to pipes, valves, and sprinkler heads and not enough will render your sprinkler system ineffective. Typical pressure limits for proper sprinkler function is between 40 and 65 PSI.
- Using a flathead screwdriver, turn your sprinkler system test ports to the CLOSED
- Make sure the spigot valves both inside and outside your home are CLOSED.
- Turn the water to your sprinkler system on by turning Valve C, inside your home, to the “ON” position.
- Slowly turn Valve A (located below the vacuum breaker) to the “ON” position.
- Located outside, Valve B may also now be moved to the “ON” position.
- The control clock should now be plugged in and turned to “AUTO” or “MANUAL”.
