Different Types Of Backflow Preventers Used By Professional Plumbers

Do you think all the water flowing from the tap is clean and safe

? You cannot always be sure that your tap water is not contaminated; you need to regulate your source of water such as the filtration system. How does the water get contaminated? Would it be due to damaged and rusty pipes? Or perhaps there is another explanation to the water contamination.

This is how the water in our own homes flows. When we open our tap, water will come out and this is clean. But once we dispose the water, perhaps through the drainage, this dirty water goes out through pipes that were designed for this purpose. However, because of faulty and blocked pipes, the dirty water backflow can occur. What does this mean? The dirty water that flows back will combine with the clean water supply. Then it will come out as contaminated tap water. This situation can be prevented if we maintain our pipe systems. The solution applied by modern plumbers is backflow testing.

What happens when backflow occurs? Before identifying the effect on water, let us examine how dirty the back flowing water is. You have water coming from the flushed toilet, washing or dishwashing machine. When it comes from the toilet, it can have fecal matters that can extremely be hazardous to health. When the back flowing water reaches the clean water supply, these water will contain bacteria. Thus you use contaminated water for drinking and cooking. Contaminated water can cause some diseases.

Because of these dangers, it is important that you have backflow preventers installed in your plumbing system. You cannot do the installation; you have to employ a professional plumber to install the backflow preventers. These kinds of preventers are tools installed by plumbers to prevent the backflow of dirty water. This is installed at the source of clean water.

In order for water to flow in the right direction, there should be sufficient pressure in the water line. When main pipes break, this pressure drops. Other causes of pipe break are frozen pipes and other plumbing issues. Because of this, the waste water will not flow to where it should and could just backflow into the main pipe.

Backflow preventers take the form of anti-backflow valves and plumber can use different kinds of valves. These valves are installed for the purpose of preventing the contaminated water to flow back thus keeping the water in the tap clean and sanitized. The valves will block and reverse the path of water until it flows to where it should go.

One kind of backflow valves is the air gap valves. This is the simplest backflow preventer. This is mounted below the faucet thus preventing the water to backflow to the faucet. Another kind of valve is the double check valve that functions as gate to prevent the backflow to go to the main water source thus reversing the water to the outside outlet. You also have vacuum breakers that are installed above the pipes. This makes use of pressure to prevent access to fresh water supply. There is still another kind of backflow preventer, a reduced pressure backflow. With this, you will have a separate chamber between check valves. This keeps track of pressure within the pipes.

It is imperative that you contract a plumber to install a backflow preventer in your water system. This device will prevent the dirty and contaminated water to go back to your main water source. This will prevent hazards to your health.
