Annual Backflow Prevention Device Inspection Due

Our client is located in Rockingham, WA, far from the usual videos that we have on residential properties, we also look after commercial and industrial. Richard was called in to perform the annual test for this client’s backflow prevention devices. These apparatuses are required to be installed in such properties to make sure that there is a safe water supply for the end users.  Top dog Richard, apart from being a licensed plumber he also has Backflow Certification, so he is allowed to have these tests done for such establishments.

What is a Backflow prevention Device?

For those who are not familiar with this device, they are usually installed at the boundary of commercial properties as legally required.  What they do is they keep and protect the water supply that we use daily for bathing and drinking. For example, if in any case there’s an accidental chemical spill in the water source or pipe, the device’s job is stop them from being siphoned back into the main water supply keeping it safe from contamination.  Water Corp. requires an annual test for these devices to make sure they are in good working condition.  Same thing with Richard’s testing equipment that needs to be checked every year to make sure that it is always accurate in providing results.  All these certifications are crucial as they will be submitted when all tests are done.

It’s time to start Testing

The initial backflow prevention test that is done for the backflow prevention device is checking the pressure of the water, upstream and downstream. In the video Richard already attached the differential pressure gauge in the different points of the double check valve. He started with the upstream check and the gauge needle needs to be above 7 kPa(kilopascal) for it to pass. He will do the same type of checking with the RBZ valve (Reduced Pressure Zone). After all necessary tests are done for the devices, he will write up a report and submit it to Water Corp along with the required certificates.

It is particularly important and a requirement to have a licensed professional perform this test.  The purpose of the device being tested plays an important role in keeping the water supply of the community fresh, safe and clean all the time.

In this job, Darius had a pipe that has failed inside the cavity wall. This not only makes the job interesting, it also means potentially having to cut out a big hole in the wall to work with which would simply make the building look ugly.

While cutting out a big hole would be the easy option for any old plumber to work with, our Old Dogs have some great tricks and want the best outcomes for our loyal customers.

Check out the on the spot tool modification and how easy Darius makes it look. Not only is he working with such a small hole in the wall, he cuts through the pipe, welds it and wraps it up neatly before sealing it all back up.

Imagine if you had a plumber out who insisted on using the good old hacksaw, they would need much more space to get the job done leaving a huge and unsightly patch on the building.

This is just one of the many reasons why we truly believe Plumbdog is the best in the industry. We have all the gear and every idea!
