Both have strengths for plumbing leak detection.
| Factor | Leak.ca | Acoustic Detection |
|---|---|---|
| Best for | Hot water lines, surface moisture mapping | Pressurized supply lines, all pipe materials |
| Cold water lines | Limited — may not show differential | Excellent — pressurized leak creates sound |
| Behind walls | Good — detects moisture through drywall | Good — hears sound through wall materials |
| Under slabs | Good for hot water, GPR needed for cold | Excellent when combined with GPR |
