what is the Difference between test number 1 and number 3 ?

Can you get a differential value across check#2 using this method?

Excellent demonstration 👏

do you close all all 5 valves on the gauge before starting Test #3?

I can tell you right now you will never pass a AWWA test or a USC test and especially a Ventura County test, with what they are showing you

Was this the actual test exam in Michigan?

Yeah great video just got a 5 valve test kit and it’s helped immensely

Hello, what if the checks appear to hold >1PSI, but slowly, over say 10 hours, bleed below 1 PSI? In other words, how long do the checks need to hold >1PSI to pass? Thank you!

Quit tilting the test gauge ya clown

If you add water to the air inlet valve after removing the bonnet in the air inlet test water will come out the bleed hole once the air inlet opens easiest way to verify air inlet opening I know series 5000 doesn't include that ask Sean Cleary why not

Observing the test kit gauge needle holding steady after introducing high pressure water downstream of the second check valve at test cock cock number four and closing test cock number two only indicates that there is no downstream demand. If the test kit needle holds steady this is an indication that the backflow prevention device assembly is in a static state. It does not indicate that the downstream shut-off valve (number two shut-off valve) is drip tight. Also to confirm that the second check valve is holding drip tight against backpressure, test cock number should be open. If test cock number two is closed how is high pressure getting to test cock number four to backpressure the second check valve. After applying high pressure water downstream of the second check valve one should observe the relief valve port. If water does not discharge out of the relief valve and there is no downstream demand, the second check valve is considered drip tight with backpressure. If water discharges continuously out of the relief valve when applying backpressure to the downstream side of the second check valve, this is an indication that the second check valve is not hold drip tight against backpressure. (Disc compression should be taken into consideration if a discharge is noted but stopped.) When evaluating the first check valve the actual differential pressure reading should be recorded on the test report form.

Very helpful to learn

These guys are great, they really give you the full understanding of these devices and the importance to their real world application!

Excellent video. My exact procedures to the T.. Excellent instructions, simple, and to the point.
