Clean water is a necessity
for a successful society, and a backflow problem can result in the
contamination of clean water. Even though the advances in modern plumbing have made
better sanitation practices and better waste removal, leading to the
ratification of various diseases, issues with backflow still occur. As a
result, this can pose a health risk, as contaminated water could contain germs,
bacteria, and chemicals that transmit diseases. This is where backflow prevention Brisbane is necessary and it starts with detecting any potential sources of
contamination.
Why Water Pressure Drops?
Sudden drops in municipal
water pressure can happen in many ways, causing backflow. Common origins involve
the failure of a municipal pumping station, a broken water main, or the opening
of a fire hydrant to release a high volume of water. When a huge amount of
water pressure is removed from the system, water could be drawn back into the
system at other surrounding points.
How to Prevent Backflow?
It is essential to schedule
an annual backflow inspection to discover any potential sources of
contamination. A professional plumber can install devices in the system
anywhere wastewater and freshwater are cross-connected. As long as municipal water
flows in one direction, the backflow device stays open. If the flow reverses,
the device stops the contaminated water from penetrating the system.
Types of Backflow Prevention Devices
There are main types of
prevention devices that a backflow prevention Brisbane specialist may need to use to
control your problem. Depending on the cause of your issue and the water system
within your property, the expert may install one of the following options:
Spill-resistant pressure vacuum breaker assembly. This method utilizes internally loaded check valves and an air inlet
valve that is operated independently on the discharge side of the check valve.
It can be used for health hazards or non-health hazard problems but is only
successful for back siphonage concerns.
Pressure vacuum breaker assembly. This refers to the use of a spring loaded check valve and dual
shutoff valves to stop back siphonage. However, it may not work for back
pressure backflow and can be used for non-health or health hazards in the waterline.
Double-check valve assembly. This backflow prevention Brisbane option uses two spring-loaded check valves
and shutoffs at every end of the assembly. It is suitable for both back
pressure backflow and back siphonage, but is only used for non-health hazards
within the system.
Reduced pressure assembly. This backflow prevention method uses two spring-loaded check valves
as well as a hydraulically operating relief valve. It can be used for health
hazards and non-health hazards and works on both types of backflow.
Regardless of the exact
cause of your backflow problem, it is critical to identify it and begin taking
steps to control and managing it correctly. Contacting a backflow prevention
expert to review your home and determine which of these is the right prevention
device for your property. This also identifies and addresses underlying causes.
Moreover, it can fix problems with plumbing lines that are causing the
backflow, along with the addition of a prevention device.
