Why is my water bill so high—could it be a leak?

Signs Your Sprinkler System Might Be Leaking
Soggy spots in your lawn, especially when you haven’t watered recently

Unusually green patches (water pooling underground in one area)

Water bubbling up around sprinkler heads when off

Dripping sprinkler heads even when the system isn’t running

Valve boxes filled with water or mud

Visible spraying or gushing during watering (especially from cracked pipes or busted heads)

Low pressure or weak spray in certain zones
