Gate Valve Problems

A household gate valve is used to close the gravity water supply well, which is currently under repair to temporarily shut off the water supply.

My gate valve is stuck and open, what should I do

If your gate valve is open and you cannot close it, then the only option is to drain it. In some cases, plumbers can quickly replace valves, but this does not pose a risk. In most cases, when your gate valve has a problem, if your gate valve is open, it is best to drain the water.

The problem that the gate valve cannot be opened

If you have a gate valve that cannot be opened, it is usually due to a broken spindle. The reason for this usually rest is that when the valve is closed due to not dirty build, scale, or other, the plumber or master will tighten the thread causing the thread to break. If the valve cannot be easily closed, it is best to replace the gate valve while draining water, so as to further avoid gate valve problems and cause more costs.

How to replace the gate valve without losing hot water

The best way to replace the valve is to freeze the pipe first, and then replace the valve. The only other way is to close the gate valve and disconnect the bottom pipe. Once you leave the top nut of the supply pipe, you can switch the valve very quickly. This must be done by a skilled emergency plumber.

My gate valve can’t close properly, why?

The reason why the valve cannot be closed normally is that as the gate valve ages, you will find dirt or scale accumulation, causing the closing mechanism to fail to close normally. The best way to solve this problem is to either clean the valve thoroughly or replace the gate valve.

When replacing the gate valve, whether it must be emptied first

As explained in the previous paragraph, to replace any valve, you don’t always have to empty it, as long as you have the experience and tools to do so.

What causes the gate valve to rupture

The reason for the rupture of the gate valve is that the valve is fragile and the pressure is too high when the gate valve is closed. The spindle thread is not deep enough to enter the valve, so if the pressure is too great, there is not much room to stop any resistance. It's a bit like breaking a twig instead of breaking a stick.
