- Breakdown on the possible failures and diagnostics that you may encounter on the ABPA or similar AWWA and local exams that are based on the USC 10th Edition for the Reduced Pressure Principle Backflow Preventer ( RP ) - more info and resources at www.krugerstraining.academy
We dont hate on guys that give free lessons! thanks dude!
Definitely would like the videos with the 5 valve gauge, and leaving out how to set up the fails would be helpful. It gets distracting when explaining what needle valves to turn. The video is appreciated.
Please make 5 valve videos.
Great !
Having a leaking #2 shut off valve in the direction of flow. After you bypass water from TC1 to TC4 to compensate for the #2 shut off valve leak to obtain the relief valve opening point, can you then obtain the tightness of the #2 check valve?
Yeah the bypass tests the CV-2 against backpressure
How would you test a 2nd ck and record 1st ck in the field under a leaking sov#2 with back pressure?
Good question .. since most ABPA / AWWA / county exams don’t have the capability of simulating back pressure we don’t cover it as thoroughly in the videos, but there is a process outlined in USC 10th ( diagnostic 9.2.2.3.6 for 2 valve / 9.2.1.3.6 for 5 valve ) basically you close TC-2 to confirm back pressure condition ( on the test it would not be false ) and then close TC-4. You would record CV-1 apparent as the differential pressure ( back pressure would indicate no flow condition ) record RV opening point, and record CV-2 as tight, with a note saying “ leaking #2 shutoff with back pressure “ .. so essentially if the gauge reading increases, the extra steps are close TC-2 then TC-4 .. and then write down the results with the note .. assembly passes .. but again we omit it from the videos since it’s super unlikely ( but i suppose possible using PRVs and elaborate piping setups ) to encounter on a standard exam
Please make the same video with 5 valve.
We sell the 2 valve kits and it’s the basis of our course
I can simulate everything in the USC manual with my simulators
Yeah you definitely can but it’s a lot of stuff and most (maybe 90% that I have seen) don’t .. Multiple failures can’t be simulated on the test and most proctors don’t bother with the RP backpressure but sometimes you see ones that do
Been in irrigation for 30yrs. Just stumbled on your videos. You need to slow down on explaining pretty much everything and the camera work is really bad.
Yeah I was thinking about re-doing them .. it was on the fly at one of our classes and basically reads through a study guide that we give students .. but anyway thanks for watching!
@@thebackflowbro6864 should re do them thank you !
This is really confusing. I would start with the basics.
Yep we have the base testing video out there also .. this is the advanced one with the failures
half assed
Stop trolling haha
