The water pipe is externally threaded, and an inner threaded angle valve can be used. The water pipe has an outer wire, you can use an inner wire angle valve. When installing, pay attention to the rubber ring gasket in the metal hose and pay attention to the proper length. It is recommended to buy two kinds, hard corrugated pipe and soft metal hose (black wire stripes). It is time to install the metal hose. The joint should be horizontal or vertical. If the water pipe and gasket are not well sealed, the water will leak without wrapping the raw material tape. The ball valve can be used as a valve, but it is easy to leak water. You can feel it after installing it a few more times. Don't use brute force when screwing it.
