How A Backflow Preventer Helps You

Under normal circumstances, a potable water supply is able to maintain enough pressure to allow water to easily flow from the water source to the tap, shower, or other fixture. However, there are times when your water pressure is greatly reduced due to such things as a break in a water main or frozen or broken pipes. Low pressure may also be due to emergency situations as when there is a large fire requiring several water hydrants to be used all at once.
Significant drops in water pressure in your potable water pipe may allow contaminated water from the soil, a holding pond or some other source to be siphoned up through the pipe into your water system contaminating your water supply and leading to serious and even life-threatening diseases.
A backflow prevention device is designed to block contaminants from getting into your water system protecting your drinking water and your health.

How A Backflow Prevention Device Works

In most situations, an air gap is the most cost-effective and reliable type of backflow prevention. An air gap is simply a vertical space of air between any device such as washing machine that connects to your plumbing and your water supply.
However, there are some situations where a minimum air gap distance cannot be installed and in these situations, a mechanical backflow prevention device must be installed. A backflow preventer allows water to flow one way through a backflow valve and then the valve closes to prevent water from flowing back through the pipe. Since backflow preventers are mechanical they are subject to wear and tear and therefore need to be inspected and tested regularly to ensure they are functioning properly.

Backflow Assembly Plumbing Services

Here at Lloyd’s Plumbing Inc, our skilled technicians can perform annual backflow testing, certification, repairs, maintenance and installation for any type of backflow assembly system. Some of our backflow services include:

Backflow Testing and Certification

Backflow valves are required to be inspected and tested in compliance with the local law and done by trained and certified technicians who cannot only conduct the test properly but can also properly assess the results of the test. The testing itself is done at the time of the backflow preventer is installed and annually after the installation of the device by a visual inspection of the backflow prevention device followed by conducting a physical test by inserting a gauge into a backflow prevention valve and checking the pressure. The technician then accesses the results of the tests and if the backflow prevention device is working properly issues a certificate certifying that the device was tested and passed the test.
Backflow testing is not only required by local law in both Ventura County and Los Angeles County so that the tests can catch potential problems before they occur, which can prevent people from becoming ill from contaminated water.
Should your backflow prevention device not passed the annual test, the technician from Lloyd’s Plumbing Inc. can repair the backflow preventer right on the spot so that you have the certified working backflow device.

Backflow Repair and Replacement

If when a backflow prevention device fails to work properly when tested by a certified technician then the device either needs to be repaired or replaced. Our Backflow experts here at Lloyd’s plumbing are skilled at both backflow preventer repairs and replacements.
In some cases, the backflow prevention device can be repaired at a reasonable cost, but in some cases making repairs may be more costly than replacing the entire device. In other circumstances, the backflow preventer may simply be too worn out to repair making replacement of the backflow preventer a necessity.
Should a repair or replacement be necessary, our technician will explain to you the problem with your backflow preventer and what needs to be done to correct the problem. Once the repair or replacement is completed a new test is done so a certificate can be issued showing that the device is now working properly.

What Causes Backflow?

Backflow is the reversal of flowing gas, liquids or suspended solids into a portable water supply. Backflow preventers are places at the points where a portable water system connects with a non-portable water system to prevent the backflow of contaminants. Backflow occurs either through back pressure or back siphonage.
Back siphonage occurs when higher pressure fluids, gases, or suspended solids move to an area of lower pressure fluids. A significant drop in the pressure of the water delivery system creates a suction, which draws unwanted and contaminated material into your water system. Siphoning that occurs in this manner is referred to as an indirect cross connection.
Backpressure occurs when the pressure of a non-potable system becomes greater than the pressure in the water distribution line causing the liquids, gases, or suspended solids in the non-potable system to be forced into the pipes of your potable water system and causing contamination. Backpressure backflow is referred to as a direct cross connection.
Backflow preventers are designed to protect both siphoning and back pressure from occurring by a shut-off valve that prevents siphoning and material from back pressure from entering your water pipes reducing the risk of contamination.

Why Backflow Testing is Important

The human body needs to have clean uncontaminated water in order to survive. However, there are many things that can easily contaminate a community’s drinking water such as toxic chemicals used to descale commercial boilers, bleaches and other chemicals used in power washing and even contaminants in the soil. The only way to tell if a backflow prevention device is working properly preventing contaminants from getting into your potable water supply is to test that device periodically to ensure it is doing the job it is meant to do, and keeping possible contaminate separate from drinking water supplies. Without backflow testing, there could be high incidents of serious medical problems and even death caused by people using contaminated water they thought was clean.

Backflow Prevention Regulatory Requirements

A backflow device is installed onto your plumbing system to protect your drinking water and the city water supply from contaminants. Backflow devices are designed to prevent backflow or back siphoning of possible contaminated water into a potable/drinking water system. To prevent backflow contamination many health organizations require an air gap or mechanical water backflow prevention assembly to be placed between the water mains delivery points and local storage or use.
In the US the EPA holds water suppliers responsible for maintaining a certain level of purity of potable water systems. It is required annual backflow testing of the backflow valves on existing backflow prevention devices.
