10. If the water in the bucket does not equal the calculated flow
on the plan, review the troubleshooting checklist and perform
the flow test again.
11. After a successful flow test, complete the Uponor
AquaSAFE flow test form and send a copy of the results to
Uponor Construction Services and the AHJ (when required).
It is also important to keep a copy for yourself.
Troubleshooting
All flow test failures fit into one of the following three categories.
1. Problem in the system supply
2. Problem in the system piping
3. Problem in the flow test procedure or equipment
In the event of a flow test failure, make sure all valves
(angle-stop valve, curb stop, main shutoff valve, flow test kit
valve, etc.) are completely open and free from obstruction.
Perform the flow test again and get an accurate residual
(flowing) pressure from the gauge you installed. Since each
system has been hydraulically calculated to perform at a
certain pressure at the main shutoff valve, the pressure reading
will help determine whether the problem is upstream in the
supply pipe or downstream in either the system or flow test
assembly. After you have a pressure reading, contact Uponor
Construction Services at:
