How to repair the key magnet of water meter valve

The reason why the water meter valve key lost its magnet may be that the magnet is aging or damaged by external force, which leads to the weakening or falling off of the magnetic force. There are several ways to fix it:

If you have a spare magnet, you can install it directly on the key, and then open the valve 3 with the key.

If there is no spare magnet, you can use a strong magnet to move slightly along the valve cover, cooperate with the stethoscope to determine the position and number of magnetic points, and make a good mark. Then prepare a corresponding number of magnets, and attract the magnetic points to open the valve 2.

If you don't have a strong magnet, you can also hold the valve stem with a wrench or vice, and then turn it to open valve 2. This method may damage the valve, so it is not recommended to use it frequently.

If you don't want to do it yourself, you can also ask the locksmith to come to the door to unlock 2. This method may charge a certain fee.

If you want to change a new valve key, you can buy 1 online. The price and quality of different brands and models of valve keys may be different. It is recommended that you choose after careful comparison.
