Backflow Compliance Is a $12B Market. Most Plumbers Ignore It.
Annual backflow testing is required by law in most jurisdictions. Sterling automates the entire compliance workflow — from scheduling to certification filing.
The Compliance Opportunity
Every commercial building and many residential properties are required to have annual backflow preventer testing. Yet most plumbing companies treat it as an afterthought — a low-margin service they do when customers remember to call.
The Problem
- 60% of backflow tests are overdue at any given time
- Most plumbers don't proactively remind customers
- Municipalities are increasing enforcement and fines
- Each test generates $75-150 in revenue with minimal labor

Revenue Math
| Scale | Annual Tests | Revenue | Time Investment |
|---|---|---|---|
| 100 devices | 100 | $12,500 | ~2 hours/week |
| 500 devices | 500 | $62,500 | ~8 hours/week |
| 1,000 devices | 1,000 | $125,000 | ~15 hours/week |
The beauty of backflow compliance is that it's recurring, predictable revenue with high margins and low competition — because most plumbers don't bother to systematize it.
