Installing a backflow prevention system in your Hinsdale, IL home ensures the safety of your water supply. RentWerx rental services highlight that backflow preventers stop contaminants from entering your home’s freshwater lines. These simple devices protect your house from costly water damage while shielding your family from dangerous pathogens and chemicals.
What is a backflow prevention system?
To understand what a backflow preventer is, you must first understand what the term “backflow” means. Backflow describes any situation where your clean water supply is contaminated by non-potable water from other parts of the plumbing. This is usually due to an unwanted reversal of water flow in the plumbing system.
Backflow happens for various reasons. Common causes are burst pipes, drastic changes in the system’s water pressure, or when high demand in one part of the network creates temporary vacuums in other parts of the plumbing system. These problems can be divided into two categories, namely, backpressure and back siphonage.
Backpressure happens when the pressure in the downstream section of the plumbing – that is, the non-potable section of the system – exceeds the pressure in your water supply lines. Back siphonage occurs as a result of negative pressure on the supply side of the system, specifically in your freshwater supply lines.
Due to the presence of cross-connections in your plumbing, these problems can result in the unsanitary water inside your wastewater pipes flowing into the clean water supply lines. Cross-connections are points in your plumbing where it is possible for non-potable materials to come into contact with potable water.
Common examples of cross-connections include submerged hoses inside pools, water heaters, irrigation systems, toilets, boilers, and fire sprinkler systems. Any of these connections can potentially draw non-potable water into your drinking water supply without your knowledge, posing a significant health risk to your family.
However, this is where a backflow prevention system enters the picture. Backflow prevention systems stop anything that can accidentally pollute your potable water supply, whether that contaminant is sewage, industrial waste, or unsanitary water. They protect your household by ensuring that you are not unknowingly ingesting contaminated water.
The benefits of a backflow prevention system
Maintain water safety
The first and most important benefit of a backflow prevention system is that it ensures the safety of your drinking water. Because you have no way of predicting when backflow can happen in your plumbing, you need a backflow preventer to constantly guard your potable water system.
Protect your family’s health
Contaminants entering your home’s water supply expose your family to deadly waterborne diseases and other health problems. Problems like this don’t go away unless they are dealt with at the root. Installing a backflow prevention system is the best way to deal with the problem.
Ensure plumbing system integrity
A backflow prevention system helps to maintain the structural soundness of your plumbing system. It promotes the overall reliability of your plumbing by ensuring safe water distribution and waste disposal. Installing a backflow preventer helps to prolong the lifespan of your plumbing.
Compliance with local regulations
Most residential properties in Hinsdale, IL, are required by law to have a backflow prevention system – RPZ valves – installed in their plumbing. These systems are mandatory for homes with lawn sprinkler systems, swimming pools, hot tubs, or fire suppression systems.
Guarantees peace of mind
Given the existence of multiple cross-connections where backflow can happen in your plumbing and in view of the fact that you have no way of knowing when your water becomes contaminated, it makes perfect sense to install a backflow prevention system in your home for peace of mind.

Signs that your home needs a backflow prevention system
If you have experienced the following signs of water contamination in your home, you most likely need a backflow preventer.
Water discoloration
If your water has suddenly acquired a strange color, taste, or smell, it could be a sign of contamination. You may also notice stains on clothes and clothes washed with that water or watermarks on the plumbing fixtures in your home.
Abrupt changes in water pressure
Sudden spikes or dips in water pressure are often a sign of plumbing issues that can result in water contamination. These changes may be due to leaks, pipe damage, and other hidden plumbing issues.
Visible backflow
If you see water flowing back in places where it should not, you may have a problem with visible backflow. For instance, if running the water in one of your fixtures causes water to flow backwards in another, you may have backflow issues.
The following risk factors increase the likelihood of backflow in your plumbing: you have an irrigation system, you get your water from a well, or you have a swimming pool, chemical injectors for pools/gardens, a bidet, boilers, and an underground water tank.
To ensure that your water supply is not compromised and your home is safe from backflow, it is best to have your water tested. A licensed plumber in Hinsdale, IL can conduct this test and advise you on how to protect your family from this danger.
