Dig in and fix it is your best advice. I had no clue how sprinkler systems work and figured it out quickly by working on mine (replacing heads, water lines, valves, electric valve wires etc).

Dig up the leaking head - either the head is leaking or the water line to the head is leaking. Either is easy to fix with a few parts from Lowe's/Home Depot.

You will probably need a crimp tool (~ $15.00) and crimp rings (~$10.00 for a bag of them) and possibly a few new sprinkler heads (~$10.00 ea).

Fixing leaky manifolds (the part that takes an inlet line, connects it to valves and distributes the water to multiple lines/zones throughout the yard) are a bit more tricky to fix or replace, but is definitely a home owner kind of project.

Good luck, Gordo
