Leak Detection in San Diego: questions
How do I tell if my San Diego leak is irrigation or the house?
Turn off irrigation at its valve and watch the meter with all fixtures off; if it still moves, the leak is in the house.
Should I repipe after multiple pinhole leaks?
Repeated pinholes usually mean the copper system is deteriorating; repiping is often more economical than ongoing repairs.
Can slab leaks be repaired without breaking the floor?
Rerouting the line through walls or the attic avoids concrete work.
