5 Causes Of Weak Lawn Sprinkler Spray
There are several possible causes when it comes to weak sprinkler spray. Sometimes only one sprinkler head is affected, while in other cases multiple emitters may suffer from weak spray. Finding the cause requires a bit of troubleshooting.
1. Engaged Backflow Preventer
The backflow preventer is fully engaged when the system is winterized so that moisture doesn't get into the lines during the off-season. If you notice weak spray during the first irrigation of spring or early summer, then the backflow preventer valves may still be partially engaged.
