There are two valves at both ends of the water meter. I know that the valve at one end of the water meter is a water valve. What's the other valve for? Open, there will be exhaust noise
Generally speaking, domestic water meter, water inlet valve is the main, the water back to the valve, to prevent water flow, other circumstances please describe in detail, thank you
The front valve controls the pipe in the home for the user. After the table valve is the encryption valve, to use special tools to open. Maintenance water meter. Debt prevention.
The end of the inlet of the water meter is a manual internal threaded gate valve that closes. And the end of the water, there is no operable handle and so on. That is a swing check valve, to prevent water from flowing backwards and to break the leaf in the water meter. This is usually the way it is installed.
