Sprinkler repair
Low water pressure in the whole sprinkler system?
If it worked fine and the pressure suddenly dropped, suspect a break or fault. Do a few quick checks, then call a pro.
Quick take: Worked fine, then pressure dropped in every zone? Check for a break or leak. Water pooling between cycles can be a sign of an underground leak (EPA WaterSense). Get a pro to check for a break →
Check this first
- Make sure the water is on. After winter shutdown, the irrigation water supply valve must be opened again (Hunter).
- Look for wet spots. Between watering cycles, water pooling on the surface can be a sign of an underground leak (EPA WaterSense).
- Run each zone and watch. Look for broken heads or water gushing from the ground, and flag them (EPA WaterSense).
- Do the meter test: read the meter before and after two hours with no water use. If it moved, you probably have a leak (EPA WaterSense).
- Only one zone weak? That points to that zone, not the main line. See low pressure in one zone.
When to call a pro
Pressure dropped suddenly in every zone? If you’re unsure about a repair, the EPA says go with a pro (EPA WaterSense). The EPA suggests hiring an irrigation professional certified by a WaterSense labeled program (EPA WaterSense).
