If the water pressure in a wall-mounted boiler is too high, you may need to open the water supply valve to refill it. But what if the water supply valve won't budge? Let's take a look.
I. What Could Cause the Water Supply Valve to Be Inoperable
1. It may be due to the user mistakenly turning it in the wrong direction. Typically, the water supply valve should be turned counterclockwise to open it. If the user turns it clockwise, it will only tighten the valve further, preventing it from being opened.
2. It could also be because the valve has been in use for a long time, leading to rust. In this case, you should apply some lubricant to the rusted area and use pliers to turn the water supply valve open.
3. Another possibility is that the water supply valve is damaged. In this situation, you should replace the old valve with a new one.
Note: When the water pressure in the wall-mounted boiler is too low, you need to open the water supply valve to refill it. If the pressure gauge reads 1.5 MPa, make sure to turn off the valve promptly to stop the refill. If you do not stop it in time, it may lead to overfilling, causing the pressure to rise. If the pressure exceeds 3 MPa, you will need to open the pressure relief valve to release excess pressure.
II. Important Points to Note When Using a Wall-Mounted Boiler
1. Monitor Water Pressure
You should regularly check whether the needle on the pressure gauge is within the specified range. Generally, the needle should remain between 1 and 1.5 MPa. If the needle exceeds 3 MPa, open the pressure relief valve. If it falls below 0.5 MPa, open the water supply valve to refill.
2. Prioritize Safety
If you need to leave home for an extended period, you should turn off the water supply valve. During winter, it's important to drain the water from the boiler to prevent freezing. Additionally, regularly check the pipes and connections for any damage or leaks. Be careful not to touch these pipes with your hands, as they can be hot and lead to burns.
This is a detailed introduction to the possible reasons why the water supply valve on a wall-mounted boiler may not turn, as well as key points to consider when using the boiler.
