By providing products only of the highest quality, Wilkins remain true to its dedication in minimizing the probability of exposure to potentially harmful elements. As a functioning group structure, people have always taken the extra steps in preserving their safety. Systems were built with the aim of avoiding conflicts that would possibly reduce our numbers. If great leaps were taken for this cause, the efforts must be continued in all ways possible. Depending on the specifications of your project, the right type of Wilkins backflow preventer will surely be reliable in preventing backflow that could be a source of contaminants.
What is a backflow exactly?
Backflow is the flow of water in the reverse direction it is supposed to be going. It is caused by either back pressure (the pressure is increased pressure on the system compared to the source) or back siphonage (the pressure on the source is lowered below that of the system). Living in a perfect world where all water repels non-water forms, backflow would never be a problem. However, this is not the case. It is very possible for your water source to be contaminated. What a backflow does is expose the clean water supply to possibly dangerous ones. A good preventer like the different available Wilkins backflow devices eliminate this possibility by having an effective mechanism in keeping your water sanitary.
The Different Risks of Contamination from Backflow
Knowing what risks you are probably opening yourself to when you do not use the necessary device is an important consideration when purchasing a proper Wilkins backflow preventer.Although you must never be caught off-guard, it is important not to exaggerate the extent of real damage that can be done to you. There are five levels of classification, depending on the gravity of water contamination.
Category 1. No risk
The water is potable and is safe for drinking. This is not very common when it comes to backflow. There are many factors and contamination sources that can compromise its quality.
Category 2. Aesthetic quality affected
Although the category two means it is not safe for human ingestion, it could still be utilized for other purposes such as cleaning the dishes or as taking a bath.
Category 3. Slight hazard from substances of low toxicity
At this level, the last thing you should want is to use it with anything that touches your mouth. This means at most, this water can only be for cleaning your clothes or for watering the plants.
Category 4. Significant hazard
If you grow your own produce and spray them with pesticide, the backflow may contain Category 4 water. This type has limited usability for you. Think washing your car or watering your produce (since they have pesticide as well).
Category 5. High hazard
Unless you are a big fan of E. Coli, this cannot be utilized for whatever purpose. Human waste is very dangerous even in small accidental ingestion. Like all water waste, this has to be thoroughly processed in order to be good for consumption again.
Now that you are aware of the specific category your water waste falls under, the best and informed decision can be made on purchasing your Wilkins backflow preventer.Along with the knowledge of the type of devices available to you, you will surely be able to get the one suited for your needs.
How does a Wilkins backflow preventer work?
Instead of dealing with the technicalities, simply go back on the causes of backflow: back pressure and back siphonage. Logic dictates that because the basic function of the device is to prevent backflow (hence, the term backflow preventer), each of them has what performs that particular job. Two Wilkins backflow parts play a role in addressing such: the check valves and the air gaps.
This is responsible for handling and inhibiting back pressure. Risk of contamination category two can be impeded by a single check valve, but a double check valve may be required for category 3. Unfortunately, this alone is not enough in dealing with water that has remnants of human waste and other high-hazard contaminants. The Wilkins backflow preventer of this kind is highly recommended for its sturdiness and efficiency.
Unlike check valves, this is able to prevent both back pressure and back siphonage. Air gaps are literally gaps that vary in size, depending on what risk categories being handled. That being said, it can be small or large. The appropriate size relies on the amount of incoming supply, because the closing of the gap caused by the overflow is being avoided at all costs. The Wilkins backflow air gaps, in preventing back pressure, replace the main pressure with the pressure of that from a raised gravity reservoir.
Backflow poses real dangers to health and to safety. Facing the possibility that something as extreme as human excrement is floating around in microscopic bits in your water supply, what would you do? Wilkins backflow preventers have always been a reliable in impeding backflow. Yes, there may be other choices, but would you really entrust your safety with something less than excellent?
