Backflows are not only annoying and inconvenient. They are even detrimental to the health of the people residing in the property where they happen. Backflows do not only make your water dirty but also contaminate it with harmful bacteria that once ingested, can lead to all sorts of diseases such as nausea and diarrhea. Read on to better understand what backflows are and what you can do to prevent this plumbing issue.
What are backflows?
A backflow is the turn-around of liquid from its correct flow direction. For instance, instead of wastewater flowing through the same pipe, it goes to a cross-connection and invades the clean water pipes. When this happens, water contamination ensues. Backflows will affect your day-to-day routine. They will make your clean water unusable. You won’t be able to use it for drinking, cooking and even for bathing because there are just a lot of risks involved.
What causes backflows?
Backflows are generally caused by two factors: backsiphonage and backpressure. Backsiphonage happens when there’s a negative pressure in a clean water supply line. This pressure draws the water from the sewage line into the clean water supply line.
Backpressure, on the other hand, happens when the pressure in the sewage line is greater than the pressure in the clean water line. This usually happens when the fire hydrant is used to stop a fire. Because most of the water is being pumped out by the fire trucks, a siphoning effect is created in the system thereby sucking the sewage water into the clean water lines.
Backflow Preventer Installation
Fortunately, there are backflow preventers now that can prevent this plumbing emergency. Backflow preventers thwart the reverse in the flow of liquid inside plumbing lines. Because of these devices, sewage is kept inside the drainage lines even when backpressure and backsiphonage happen. However, you should know that only licensed contractors can install these devices. Also remember that these devices are inspected annually to ensure that they’ll still work as efficiently.
Are backflow preventers required?
It depends on the state and local building codes. But if these things below pertain to you, you’ll be required.
1. You have a well in your property.
2. You have a lawn sprinkler system.
3. You are hooked to a utility supply.
4. You recycle gray water from your laundry or shower for watering the plants and other activities.
5. You have hosepipes that you use to:
a. flush a car radiator
b. fill a pool, fish pond or a container for your pet’s shampoo
c. mix herbicide and other garden chemicals in buckets
d. flush clogged drain pipes
