Failures usually caused by grit in the check cones, if bought new and fails. A) Manufacturers releasing faulty products B) onsite testing kits need collaboration requirements.
Thanks for taking the time to view the video and submit a comment. The relief valve will discharge if the first check valve is fouled open with debris and the RPZ is in a static state, a common problem. Flushing before installation is always the best practice. If there is debris in the inlet line a strainer should be installed. Most state drinking water program regulations and public water system cross-connection control programs will require the test kit to be calibrated annually. The manufacture will specify annual calibration.
Thanks so much for your video You've got great instructions without rushing through it I was going to build my own rig out of the differential gauge hoses and Associated fittings Can you recommend a website or video for doing that? Thanks again
Thanks for the comment. I have not encountered a video for making a backflow test kit, but I have tried unsuccessfully. The differential gauge is available, but purchasing a test kit in the long run was more economical. Also, the test kit would have to be calibrated. Getting used test kits and parts is an option that I have used.
Jimmy, what test procedure are you using here specifically? It seems to have portions of several including a confirmation test on number two check. Nice addition but not mandated by either ASSE or USC. Some of your terminology is different than ours in Michigan but that is not a major in my opinion.
Jeff, thanks for the comments. The test procedures used in my videos are commonly known in the industry as the “New England Water Works Association Three Valve Test Procedures.” They were first published in the 1973 issue of the EPA Cross-Connection Control Manual, using a five-valve test kit. However, since then, NEWWA has selected to concentrate on instructing individuals enrolled in the NEWWA backflow tester training on how to test backflow prevention device assemblies using a three-valve test kit. The NEWWA three-valve test procedures are listed in the fourth edition of the AWWA M14 Manual. The test procedures were recently revised to include analyzing the test results of backflow prevention device assemblies. The revised test procedures will be listed in the next edition of the AWWA M14 Manual. Copies of the test procedures are available through NEWWA Regarding the RP second check valve differential test, NEWWA feels it is necessary to not only backpressure the second check valve on an RP but to evaluate the condition of the second check valve spring by measuring the differential pressure across the second check valve. Measuring the differential pressure across the RP second check valve also assesses the presence of backpressure. Not sure why ASSE or USC does not require the differential test across the RP second check valve. USC states the differential test of the second check valve is optional. Both ASSE and USC state that the RP second check valve shall be equipped with at least a one-pound spring. How does one know if the RP is meeting the standards if the RP is not tested against the standards? If backpressure is applied to the second check valve and it is holding drip tight, the RP is providing protection, but is the RP meeting the standards.
There is a video without music for testing the RP. Sorry, you did not like the music; I may remake the videos without music when I have time. I am presently working on other videos without music. Nonetheless, I hope you found the videos useful. Thanks for the comment.
Thanks for viewing my videos. The plumbing code requires all testable backflow prevention assemblies to be tested upon installation, after a repair and annually. The states have different requirements as do the public water systems. Most will require the RPZ to be tested at least annually. You should check with the public water system to determine the testing requirements for backflow prevention device assemblies.
Hey Jimmy, new to testing. Bought a couple bfps to practice on. Working on rpz, 3/4. Long story short, cleaned seals and seats on check#1 and relief. No drips when shut off downstream valve. When testing differential on check 1, relief opens when bleeding high side. Any help greatly appreciated.
Not to worry. What is happening is you are diverting high-pressure water away from the sensing line which is keeping the relief valve closed when you open the high control valve on the test kit. Test cock number two is close to the sensing line. Close the high control valve and continue with the test.
@@JimmyBackflow should have stated, relief opens after shutting high side after bleeding air. So test would still be valid then? Thanks for your time,help,response.
@@connpiper If water did not discharge from the relief valve after closing the downstream shut-off valve, the first check is holding drip tight provided that the RP was in a static state. If after bleeding the air out the high side of the test kit and the relief valve discharged and stopped, fluctuating inlet pressure was the cause. Continue with the test.
It is state dependent. What state are you working in. Some states require internal inspections but only on testable devices installed for service protection. New Jersey regulations require a Physical Connection Permit be obtained by the owner of a facility where the physical connection installation is to be made with a community water supply (Physical Connection Permits are not required for private residences). Physical Connection Permit has to be renewed annually and requires each backflow prevention device covered by the permit to be tested quarterly and internally inspected annually.

Rob F. Please provide a more detailed statement regarding your comments. What are your qualifications for making such a statement? All test procedures measure the pressure loss across the check valve. The only difference is the sequence by which the tests are conducted. In the video, the first check valve differential is measured, the second check valve is back pressured, a validation test is preformed, and the relief valve is opened by introducing pressure into the zone. Also, which is not conducted by ABPA is the differential test of the second check valve. ABPA does the same but in a different order. I suggest you read up on how backflow prevention device assemblies are tested to confirm reliability. Let me know if you would like further training!.
@JimmyBackflow guess you're not familiar with abpa. Nor with the terminology. Been a tester in the city of sioux falls for over a decade along with asse, Iowa and Nebraska specific. Also having no problem reading USC cross connections 9th or 10th edition. You should try multiple classes from multiple providers. Quit being so close minded. I watched your video and just felt a little sorry for you. Have a good one.

Jimmy your the best, thanks for all the help. Great Instructions!
Absolutely love the music can’t say it enough. Makes me want too test a backflow with class and style

Does the city require that all backflow preventers be tested every year?

Hi, We have to perform 5 year internal inspection on Backflow ?
