💩 Why it's ugly

It is plumbing paperwork with a pulse. You test devices in basements, utility rooms, strip malls, and behind buildings where landscaping goes to retire. The sex appeal is measurable only with specialized gauges.

💰 Why it prints money

Many commercial properties must test backflow assemblies annually. The work is short, repeatable, and often mandated by municipalities or water districts. Once certified, operators can build a database of recurring accounts with strong margins and low inventory needs.

🗺️ The launch playbook 🔒

First 30 days

Register the entity and get the basic insurance sorted before anything else. Call the three biggest local operators and ask what they refuse to do — that refusal list is your launch menu. Price the first ten jobs deliberately low to collect reviews, then raise rates fifteen percent.

Days 31–60

Buy the used equipment, not the new one. The route density is what makes this profitable, so cluster your first customers within a twenty minute radius and decline anything outside it.

This is the part that makes money.
