To choose a valve, you need to know the correct pipe size. All PVC pipe sizes will be printed on the outside of the pipe. PVC pipes are named after the inner diameter, which is usually called the “nominal size”.

When installing the check valve, please note that the direction of the arrow on the valve body is the same as the direction of media flow.
