When we search online for “How To Turn Off عداد مياه?”, what we really want to do is to be able to quickly shut off the water flow to prevent water from entering the home or other property in an emergency, repair, or maintenance.
However, it should be clarified that “shutting off the water” is usually not done by directly operating the water meter, but by turn off the صمام. Therefore, this question actually confuses the concepts of valves and water meters.
This article will explain the relationship between water meters and valves in detail and tell you how to properly “turn off the water meter.”
Water Meter VS Valve
What are Water Meters and Valves?
Water meter is usually installed on the inlet pipe or branch pipe. It can be divided into mechanical water meters, smart water meters, ultrasonic water meters, pulse output water meters and other types according to their different working principles.
The main function of a water meter is to accurately measure water consumption and provide a basis for user billing. Through the data from the water meter, users can monitor changes in water consumption and help detect problems such as leaks.
Water valve is used to control the direction, flow and pressure of water flow. Valves can be divided into shut-off valves (such as gate valves, globe valves), check valves, regulating valves and other types according to their uses.
Valves can control whether to supply or not supply water and adjust the water flow. This allows valves to isolate pipe sections for easy maintenance, testing and cleaning. In addition, the check valve prevents water from flowing back and ensures the normal operation of the system.
Relationship Between Water Meter & Valve
Water meters and valves complement each other in the water supply system. A valve is usually installed before and after the water meter. The main valve is usually located before the water meter, that is, between the water meter and the water source, to control the water flow of the entire water supply system. The sub-valve is usually installed after the water meter, that is, between the water meter and the water outlet, to control the water flow of a specific area or equipment.
In some countries or regions, the valve in front of the water meter is designed as a lock valve, which will be locked if the user has not paid the water bill to prevent him from using water resources at will.
Sometimes, a check valve is required in front of the water meter to prevent water flow back, causing the water meter to rotate. This is because during the water supply process, due to changes in water pressure, the water flow may flow back, causing the water meter to rotate, reducing the accuracy of the water meter data. The check valve can effectively prevent backflow and avoid water meter errors caused by changes in water pressure. Valve can also prevent damage to the water meter due to sudden changes in water flow.
Some high-performance water meter featuring a built-in check valve at the inlet port, effectively prevents water backflow. This innovative design eliminates the need for a separate check valve installation, streamlining the process and saving both time and costs.
The advantage of installing two valves before and after the water meter is that when one valve leaks or has other problems, the other valve can still be used. In addition, when replacing the water meter, closing the valve in front of the water meter can cut off the water flow, making the replacement operation easier. At the same time, closing the valve behind the water meter can prevent water from flowing into the pipe during the replacement process, causing pollution or waste.
How To Turn Off Water Meter?
In most cases, “How To Turn Off Water Meter?” is actually a question of “How To Turn Off Water/Valve?”. Here are the steps to turn off the water valve:
Step 1: Find the main water valve
The main water valve is the key valve that controls the water supply to the entire home, usually located in the kitchen, basement, outside the house, etc. Sometimes the valve is installed in the water meter box together with the water meter, and we need to use tools such as wrenches, screwdrivers, and crowbars to open the box.

Step 2: Turn off the valve
The valve switch has a knob or a long handle. The knob switch requires multiple turns to fully open or close (sometimes with the help of a wrench). The long handle switch only needs to be turned 90° to complete the closing or opening operation. Open when parallel to the pipe and close when vertical.
If the valve is difficult to close due to rust, we can try to drip some vinegar or commercially available rust remover on the rusted part of the valve. The acetic acid in vinegar can react chemically with rust to help dissolve the rust. After waiting for a while, the rust will gradually loosen, and then try to turn the valve.
We can also use a wrench or hammer to gently tap the rotating part of the valve to loosen the rust and make the valve easier to turn. Then use a pipe clamp to slowly twist the valve, rotating left and right alternately. This method requires a certain amount of patience and skill to avoid excessive force that may damage the valve.
If you are unable to close the valve no matter what you try, contact a professional for help to avoid damage to the valve or pipe due to improper operation.
Step 3: Check the closure
Open a faucet. When the water flow inside gradually decreases and eventually stops flowing, it indicates that the valve has been properly closed. At this point, you can further verify by observing whether the water meter reading is zero.
