A backflow tester cannot test a Reduced Pressure Zone (RP) device because there is no water demand and the well pump shuts off when the RP relief valve opens, preventing pressure buildup for the test.

Standard backflow test procedures assume constant water supply or demand, but this well-fed system has no demand and the pump auto-shuts when the RP opens, making the test impossible with typical methods. There is no known tool or workaround to test an RP under these conditions without modifying the system.

Workarounds Described

dumped tank water to create demand
left hose bib slightly open to maintain pressure
closed hose bib which caused RP to dump and pump stop

Implied Software Gaps

A tool that can artificially create adjustable downstream demand without causing pump shutoff or pressure loss

App Concept

Backflow Test Simulator

A portable device that creates controlled, measurable downstream demand to enable testing of backflow preventers in low-flow or zero-demand systems. It simulates draw without triggering pump shutoff, allowing proper differential pressure testing.

Key Features

Internal bypass valve to create adjustable downstream flow
Pressure gauges and data logging to verify test conditions
Compatible with all standard RP and DCVA test kits
Battery-powered and portable or vehicle-mounted

Target Users: Backflow test technicians in plumbing, irrigation, and fire protection serving rural or well-supplied properties with intermittent demand.

Revenue Model: $599 per unit one-time purchase, with optional $19/mo software subscription for test report generation
