An Introduction to Non Return Valves UK

Drainage non return valves, which are sometimes refered to as a one way drain valve, are essential in protecting both the environment and public health. They are installed in sewage and drainage systems to prevent the flow of waste materials, such as sewage and wastewater, from flowing back into the system. This is important because these materials can potentially contaminate drinking water and cause other health hazards. For example, if sewage were to back up into a drinking water supply, it could spread waterborne illnesses and diseases. In addition to protecting against contamination, drainage non return valves also help to prevent flooding by ensuring that waste materials are properly disposed of and do not overflow into surrounding areas. This can help to protect buildings, property, and the environment from damage and pollution.

Features and Benefits of Non Return Valves

One of the main benefits of non return valves is that they help to protect against flooding and water damage. By preventing wastewater from flowing back into the one way drain valve sewage system, non return valves can help to prevent the overflow of sewage and other waste materials, which can cause significant damage to buildings and property. 

Drainage non return valves are typically installed in areas that are at high risk for flooding, such as low-lying areas or areas that are prone to heavy rainfall. In addition to protecting against flooding, a one way drain valve can also help to prevent sewage backup, which can be a common problem in older or poorly maintained drainage systems.

Another benefit of non return valve sewage is that they can help to reduce the risk of health hazards associated with sewage and wastewater. Mixing sewage water with drinking water is dangerous because contaminated water is a health issue because it can contain harmful microorganisms and other substances that can cause illness or disease. When water is contaminated, it can become a breeding ground for bacteria, viruses, and other pathogens that can cause a range of health problems, from mild stomach upsets to severe infections. By preventing wastewater from flowing back into the system, waste pipe non return valve products can help to prevent the contamination of drinking water, which can be a major health concern. All of these benefits apply to the different sizes including the 110mm non return valve and 160mm versions too.

Drainage Non Return Valves at the Drainage Shop

In terms of their construction, non return flap valves for drainage are typically made from UPVC or unplasticised polyvinyl chloride. UPVC is a strong, durable material that is resistant to corrosion and damage from water, making it an ideal material for use in drainage non return valves. In addition to its durability, UPVC is relatively lightweight, making installing and maintaining one way drain valve products easier. This material is also used with Metex ratwall products as well, sharing the same benefits.
