Why a Non Return Valve is Necessary

As a plumber with years of experience, I have encountered various plumbing systems and have seen the importance of installing a non return valve. This small yet crucial component plays a significant role in maintaining the efficiency and functionality of any plumbing system. Let me share with you the reasons why a non return valve is necessary.

First and foremost, a non return valve prevents backflow. Backflow occurs when wastewater, sewage, or other undesirable materials flow back into the clean water supply due to changes in pressure. This can happen when there is a sudden increase in water demand or when there is a disruption in the main water supply. Without a non return valve, these contaminants can contaminate the clean water supply, posing health risks to the household.

Moreover, installing a non return valve also helps conserve water and reduce utility bills. The one-way design of this valve ensures that water only flows in one direction, preventing any wastage. Without it, there could be constant dripping or leaking from faucets and toilets even when they are turned off. This not only wastes water but also increases your monthly water bill.

Another benefit of having a non return valve is its ability to protect your plumbing system from potential damages. When backflow
