Get Epcor Backflow Test Report

Backflow is caused by cross-connections that have the potential of allowing contaminants into the drinking water system. Back siphonage can occur when the pressure in a tank or water trough is lower than the water system's pressure. This could allow the influx, or pulling, of contaminated water into the system.

3:14 6:02 Testing Procedure for Double Check Valves | Backflow Prevention YouTube Start of suggested clip End of suggested clip If a reading below seven kPa is indicated the upstream non-return valve shall be deemed to be faultyMoreIf a reading below seven kPa is indicated the upstream non-return valve shall be deemed to be faulty. The valve shall be repaired or replaced.

When testing a DCVA, the differential pressure gauge reading being measured is the difference between the supply pressure on the upstream side of the check valve and the atmospheric pressure on the downstream side of the check valve. valve as closed tight at the psid reading on the gauge.

Critical check valves are inspected/tested using three main methods: externally, internally and, in unique situations, in-line function testing.

Things like dirt, shifts in water pressure, chlorine and rust, and even thermal expansion can create leaks. If you notice leaks from the backflow preventer device itself or the sprinkler heads, get things checked.

A Double Check Valve Assembly is a backflow preventer consisting of two independently operating spring loaded check valves with tightly closing shut off valves on each side of the check valves, plus properly located test cocks for the testing of each check valve.

Common Issues Caused by a Damaged Backflow Preventer Water Leaks. Just like any other piece of equipment, backflow preventers will wear out over time, and as a result, it's not out of the ordinary for them to leak. ... Uneven Water Pressure. ... Cloudy or Discolored Water. ... Slow Drainage.

Your double-check valve will eventually fail; if you forgo repair or replacement, it will likely fail sooner. When your check valve fails, your water supply can fill with harmful contaminants. This can be bad for your health and seriously damage the other crucial components of your water system.

Rusted check valves – Similar to debris, rust from inside the device or piping can cause the mechanical components to seize or stop working correctly. If the device has metal components and fails its test, the parts often have to be replaced. If the components are too sized the whole device would have to be replaced.

Cloudy or Discolored Water Your backflow preventer could be in perfect working order, but if your neighbor's backflow preventer fails, they could be letting fertilizer, soap, stagnant water, and much more into your public water supply.

Damaged or defective backflow preventers can cause drain buildup, leaving unwanted messes in the bathroom and kitchen. These issues may spread throughout other water fixtures, drains, and sinks. You should also check for discolored water. Cloudy or discolored water indicates a broken backflow valve.

If your backflow preventer fails the test, it needs to be cleaned or repaired and in some cases it may need to be completely replaced and a successful re-test performed. These backflow devices fail at a rate of 10-15% after one year.
