Key Features


The kits are certified to meet all national standards for backflow testing. They can accomplish the same tests as the older 5 valve styles thanks to the way we machine our gauges.


We have updated the material compatibility of our gauges to feautre teflon coated wetted metal parts and viton seals. These backflow kits also implement a new dial case design that combats denting and cracked lenses. Furthermore, we have relocated the pressure gauge for saftey

Tripod Mount

Backflow testing requires multitasking. As a result, we have included two threading locations on the kits for a standard camera tripod. This makes taking notes, attaching hoses, and using valves much easier

Calibration Notification Program

Backflow Test Kits are required to be calibrated annually by law. As a result, we have a helpful notification system that lets you know when your kit needs to be sent back. You will receive an email notification and even a phone call if you prefer.


Every kit comes with a coupon for one free calibration. We calibrate all units in house and send them out same day. We also email you when your next calibration is due.

Visual Indicator
We utilize a clear tube to connect the high port to the low port. This helps you verify that all air has been bleed from the system
