PVC ball check valves are a vital component to almost any pressurized system. Without a ball check valve, you get backflow, and in many cases backflow can create tremendous damage and contamination in a filtration or pumping system. It works like a one-way sign on the street. Water or other fluid can easily pass through in one direction, but it won’t be able to pass back the way it came.
One-Way Flow
One-way flow is of the utmost importance to prevent contamination. In larger systems, sewers and so forth, you’ll often find swing check valves. These are doors that will only open one way, so water can easily flow out but cannot flow back in. A ball check valve functions in a similar manner. The pressure coming out of the source will push the valve open, but any pressure coming from the other direction will only push it shut.
Easy Maintenance
One of the reasons people tend to rely on PVC ball check valves is because PVC is a very easy material to clean and maintain, and a cheap material to replace. Ball check valves see a lot of action, so even the most well-made valves will eventually need to be replaced. Most can be screwed into place with a wrench or even by hand and shouldn’t take more than a few minutes to swap out.
Other Options
Two-way ball valves are available for systems where you may need to reverse the flow of water. These come equipped with a handle that can be turned one way or the other to determine in which direction you want the water to flow.
PVC ball check valves are a linchpin of your entire system. You’ll find this to be true quite often in pressurized systems. It’s the tiny components that keep the whole thing together.
