Sprinkler Backflow Preventer
Protect Your Water Supply with Reliable Sprinkler Backflow Preventers!
Have you ever considered the potential hazards lurking in your home’s plumbing system? It may not be something we think about often. But the importance of protecting our water supply cannot be overstated.
Sprinkler Backflow Preventer by Big Apple Plumbing defends your main water supply from potential contaminants. These are known by a few different names, like vacuum breakers or pressure vacuum breakers, for effective plumbing protection. The Sprinkler Backflow Preventer is a specific type that focuses on safeguarding your irrigation system. By installing it, you can ensure that water flows out to your sprinklers. Also, check water outlets don’t pose a threat to the main water supply.
How Does A Sprinkler Backflow Preventer Work?
One key challenge in maintaining clean water supplies is the potential for backflow. A situation where water flows in the opposite direction within a plumbing system creates a contamination risk.
Backflow can occur due to changes in pressure or cross-connections with non-potable water sources, posing a serious threat to public health. Sprinkler backflow preventers play a crucial role in protecting water systems.
By understanding how it works, we can maintain the cleanliness of our water supply. Let’s check how sprinkler backflow preventer work:
The backflow preventer has two check valves: a primary check valve and a secondary check valve. These valves allow water to flow in only one direction. The primary check valve is located closest to the inlet connection. On the other hand, the secondary check valve is located downstream of the primary valve.
When the irrigation system is turned on, water flows from the main supply into the backflow preventer. The pressure of the incoming water pushes against the primary check valve. It opens the backflow preventer and allows water to enter the irrigation system. Simultaneously, the pressure on the secondary check valve keeps it closed, preventing any water from flowing backwards.
During normal operation, water flows through the open primary check valve and continues moving into the irrigation system. The primary check valve remains open due to the pressure differential the water supply creates. Meanwhile, the secondary check valve remains closed due to the opposing pressure from the irrigation system.
A sudden drop in water pressure in the main supply line or a backflow event may occur. A few examples are a water main break or a drop in water pressure due to firefighting activities. In such a scenario, the pressure in the irrigation system may exceed the pressure in the main water supply. This pressure reversal would normally cause water to flow backwards, potentially contaminating the potable water.
In backflow, the pressure reversal causes the primary check valve to close. It prevents backward water flow into the main supply line. Simultaneously, the pressure created in the irrigation system pushes against the closed primary check valve. It opens the secondary check valve. It will allow the excess pressure to be released into the atmosphere. As a result, it prevents contamination of the main water supply.

What is the reason behind Backflow?
Backflow occurs when water follows the natural path of moving from an area of high pressure to an area of low pressure. Back-siphonage can happen due to some reasons:
Besides, the improper installation of a sprinkler system can also lead to backflow due to excessive back pressure from the pump. It is not the situation that you want at your place. So, get and install a good quality sprinkler backflow preventer by Big Apple Plumbing!
