A single check valve to the connection. This prevents water in the flexible hose from flowing back into your water supply. Creating a one-way system based on water pressure.
The single-disc check valve is also called a single-plate check valve, a wafer check valve: it is a valve that can automatically prevent fluid from flowing back. The disc of the check valve is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is automatically closed under the action of the fluid pressure difference, gravity and other factors to prevent the fluid from flowing back. It can be installed horizontally or vertically. For vertical installation, pay attention to the flow of water from the bottom to the top, and pay attention to whether the installation direction is correct during installation.

Check valve with single disc need to be clamped with two flanges and the flanged end check valves shall be bolted to the flange.
A single check valve to the connection. This prevents water in the flexible hose from flowing back into your water supply. Creating a one-way system based on water pressure.
Check valves need to be installed in accordance to their inlet and outlet, which is often shown as an arrow on the valve housing. As they only allow flow in one direction, if they are installed backwards, they will not work properly.
