This is a must to ensure that no spring tension is released prematurely, or any part which does not need to be removed is removed, and to ensure that the disassembly is done in the right order.

The backflow repair plumber will release all the pressure from the assembly and will then remove the components from the assembly. The working of each component will then be inspected individually for the reason of the failure of the backflow device.

The component would be then taken apart to inspect each part for wear and tear, corrosion, scaling etc. The parts are cleaned properly with a soft material to ensure there are no scratches. It is imperative for the repair professional to understand whether the part can be cleaned and put back to use or would need a replacement. It is a good idea to replace old rubber parts with the new ones for longevity of the entire components

This part could be tricky especially if the backflow prevention assembly is installed in a place where it is not feasible to have water splashing around.

But using too much of it may also attract dirt and debris and failing of the components. Hence it is critical to understand how much and where it has to be used.

Once the technician is certain that everything is in place, the next step is to pressurize the assembly and remove the accumulated air from inside the body. The technician must know about all the air bleeds and air screws designed in the body to release the air. Hence is it very important that the technician is well trained and knows the device assembly in and out
