Electrical Water Backflow Preventers

Backflow of contaminated water into the pipes that carry our drinking water is a big problem in Australia. It is very disgusting to imaging contaminated toilet, bath or wash water somehow finding its way back into the pipes that should be carrying clean drinking water, but it happens. There are many different approaches to handling this problem and many types of devices designed to prevent water backflow. Most of these services and devices are available from a local plumbing service and should be installed by a professional plumber, since they will affect the quality of drinking water.

There are many strategies to control contaminated water backflow into drinking water piping. Some of these measures are passive, while others are active. Active measures, such as electrical backflow preventers, require power and electrical devices while passive measures rely mainly on a system of check valves. The electrical type could use a small pump to make sure there is always positive pressure to keep the water flowing in the correct direction, thus preventing backflow.

Other types of passive backflow preventers are based on double check valves, air gap valves, vacuum breakers and reduced pressure detector systems. This type can’t generate positive flow and pressure but can close a valve as backflow begins.

 Backflow Preventers Types

One of the oldest and simplest backflow prevention methods is the air gap valve. Imagine a pipe with water flowing out of it positioned 2 inches over a funnel connected to a second pipe that flows down into something else. Imagine perhaps a fish pond, for instance. If the pipe supplying the water loses pressure and begins to back flow, it can’t draw water out of the fish pond because there is a 2-inch gap of air (air gap) between the pipe supplying the water and the funnel and hose leading into the fish pond. There is physically no way for the water supply pipe to siphon water from the fish pond. No contaminated water can backflow into the drinking water.

When choosing which type of backflow preventer, you want, you need to research your needs and your choices. An electrical backflow preventer works very well, maintains positive pressure and good waterflow and is perhaps the most flexible solution. Air gap and check valve systems may also work for you, but when keeping good pressure is a concern, the electrical type is best.

Repair Options for Electrical Back Flow Water Systems

If you have an electrical water backflow preventer installed, you will need to troubleshoot the electrical system and the plumbing. It may be possible that an electrician can locate and repair an electrical fault that is causing your problems. You might also need a plumber if the valve needs to be removed and replace. Since you will be dealing with electricity near water, you should let professional plumbers and electricians handle this sort of problem. Also, an improper installation could not work properly, which would result in contamination in your drinking water. It is not worth risking your family drinking water contaminated with detergent or sewage. Let the professionals handle it.
