Learn something new: How do you open the shut-off valve located upstream of the water meter?
In life, we often encounter the problem of door locks that simply won't open. Similarly, the shut-off valve on a water meter can also get stuck and refuse to budge. If you don’t have access to a professional repair technician, here’s a guide on how to open the shut-off valve located in front of your water meter.
The valve can be opened by turning it counterclockwise. However, if the valve is sealed with lead wire or has undergone special treatment, it may not be possible to open it. In such cases, simply contact a professional repair technician. If necessary, you’ll also need to prepare some tools, such as wrenches and pliers.

You can also use a magnet to confirm the location of the magnetic points and mark them accordingly. Once you’ve marked the points, simply lift them away with the magnet, and the door will open.
The above is how to open the lock valve. We hope this helps everyone resolve their issues. If you have any other questions, feel free to call us.
