Overview

Built to scale—from one tester to an entire team

The MachBackflow App simplifies testing with accurate data capture, real-time results, and secure cloud storage. Easily search and filter tests across your team for faster, more efficient backflow management.

Secure. Accessible. Always Available.

Backflow test records captured through the MachBackflow App are securely stored in the cloud using encrypted, enterprise-grade infrastructure. This ensures that all testing data is protected from unauthorized access while remaining accessible to authorized users anytime, anywhere. With built-in redundancy and real-time backups, your records are never at risk of being lost due to device failure or human error. This cloud-based approach not only enhances data security but also streamlines access, allowing teams to search, review, and share test results quickly and efficiently—supporting better compliance, recordkeeping, and operational continuity.

Instant Results. Total Visibility. Teamwide.

With the MachBackflow App, accessing test results across your entire team is seamless and instant. Real-time data transmission ensures you receive backflow assembly test results the moment they’re completed—no more waiting on paper forms or delayed field reports. This streamlined process improves communication between field technicians and office staff, reducing errors and boosting overall efficiency. Whether managing a small team or a large operation, the app keeps everyone connected and up to date.

Your Results. Your Kit. Our App.

Our app is the simplest and most accurate way to record your backflow test results. Whether you’re using the advanced 855 digital test kit—which captures line and differential pressure values directly from the kit through the app—or manually entering data from analog or previous-generation digital kits, the app ensures accuracy and consistency every time. Eliminate handwriting and typing errors, streamline the testing process, and make data entry easy with an intuitive interface designed for all testers and all test kits.

Track, Sort, and Search—In Real Time.

The MachBackflow App empowers your entire organization with unparalleled access to completed test records in real time. Whether you need a company-wide overview or want to drill down by individual tester, the app makes it effortless. Advanced filtering options let you sort by assembly type and test status—giving you full visibility into your testing operations. This centralized access reduces delays, improves oversight, and enables teams to act quickly on critical compliance issues. With powerful search and sorting capabilities, your data becomes a strategic asset, not a burden.

Assembly Autofill

The engine behind effective and agile field operations.

Easily search and load prefilled assembly data, then review and update as needed—saving time and making field testing faster and more efficient.

Searching the MachBackflow App for an assembly by serial number

Lookup the assembly Record.

Quickly search and load prefilled assembly data by address or serial number. This streamlined process reduces manual entry, minimizes errors, and ensures your field team works with the most accurate, up-to-date information available.

Verify

Check and verify assembly data.

Testers verify the located assembly’s record data. This step ensures that all critical details—such as location, assembly type, and Make—are accurate and up to date. Verifying the information helps reduce errors, avoid duplicate records, and maintain compliance. Whether using prefilled data or making updates in the field, this process ensures reliable documentation and a smoother testing workflow.

Test

Test the assembly

Complete the backflow test and seamlessly save the results to the verified assembly record within the app. Designed to accommodate all known backflow assembly types, the app supports testing using any recognized industry standard. This flexibility ensures accurate, consistent, and compliant results across your entire testing process.

PDF Report Creation

Instantly generate professional PDFs for faster reporting and easy access

Our PDF generation feature makes creating generic professional test reports fast and easy. Whether for official submissions or internal records, users can quickly produce and store detailed PDFs of test results. Integrated with our cloud-based platform, these reports are securely saved and accessible anytime through the mobile app.

Streamline reporting with built-in PDF generation right from the app

Generated PDFs are securely stored in the cloud, ensuring unlimited access anytime through the app

Easily share generated PDFs with water customers and team members directly from the app

Offline Mode

No Signal? No Worries — Offline Mode Keeps You Going.

The MachBackflow App is built to keep your workflow uninterrupted—even in areas with limited or no cell service. When connectivity drops, the app automatically switches to offline mode, storing all test data locally on your device. Once service is restored, all saved records are synced to the cloud. Failed tests are securely backed up both locally and in the cloud, making it easy to access, review, and update test results—especially during assembly repairs. This seamless offline capability ensures you stay productive and accurate, no matter where the job takes you.

Export Test Records

Simplify your workflow with streamlined backflow data export—fast, reliable, and always accessible

Eliminate the hassle of manual data entry with Assembly Test Export. Effortlessly export completed test results and tailor the data to fit seamlessly into your existing workflow. This powerful feature makes integrating test data faster, easier, and more efficient.

855® Air Inlet Capture

Capture Air Inlet Opening Values with Ease

Capturing the air inlet opening point on PVBs is now faster and more precise with our Air Inlet Capture feature—exclusively available when using the Mid-West® Instrument 855® digital test kit. The app leverages a custom-built algorithm allowing it to pinpoint the exact opening point with exceptional accuracy. No more juggling your focus between gauge and assembly—Air Inlet Capture handles the precision work, delivering a seamless and efficient testing experience.

Connect

Connect the 855® digital test kit at the critical point of the PVB assembly’s air inlet center as required to perform an accurate Air Inlet Capture test.

Capture

Properly bleed the test kit as needed, then reduce the differential pressure to 15 PSID. When ready, tap “Start Capture” in the app and continue bleeding pressure as required to perform an accurate PVB test.

Save

The app utilizes a custom-built algorithm to detect the PVB’s opening point by analyzing real-time pressure data from the 855 digital test kit. It then calculates the precise opening point automatically, providing a more accurate and reliable result—eliminating the need to look at two places at once.
