Back flow testing devices are used to prevent a water system from being contaminated or polluted when the normal, directional flow of the water is reversed. Water safety can be compromised by any liquid, solid, gas or any combination of them. The integrity of a safe water system is threatened by the mixing of any of those components, resulting in an unsafe water system for your home and your family. A back flow device location is dependent on who's installing the device, the system specifics and an owner's personal preference. Testing devices are installed either inside or outside. Outside testing devices are obviously more convenient for testers and owners. Many residential irrigation systems are placed outside, although some may also have them inside. If the backflow device installation is set up inside, the homeowner would need to make arrangements to let the installer in if they cannot be home during installation or for device testing. Since a back flow device is mechanical, it can potentially malfunction at any time. So it's essential to have all devices tested. In some areas, it's mandatory to have testing done. Where it is required, average testing times are once per year. However, if testing is not done, situations of back flow can be extremely harmful to people, animals and to property. Testing of a back flow device is a basic, simple test. All flowing water must first be turned off in order to perform the test. The test kit is connected to device ports which are accessed for the testing. Those ports are tested, and results are recorded. Official paperwork is often supplied by area Health Departments or City Municipalities. If a device is no longer doing it's job, it may be within a 5% failure category. Severe problems can be any issues with the device's castings or poppets, which are sometimes caused by freezing temperatures, water quality, device usage, water pressure or device environment. Simple issues can be due to worn or faulty seals, springs or O-rings. Symptoms of leakage, with minor drips or with constant leaking, indicate a more serious problem that can ultimately shorten a device's lifespan.
