How do I check the water pressure on my combi boiler?
Checking the water pressure on your combi boiler is an important part of regular maintenance. Low water pressure can cause the boiler to malfunction or shut down, while high water pressure can cause leaks and damage to the system. In this article, we will discuss how to check the water pressure on your combi boiler, why it is important, and what to do if the pressure is too high or too low.
Why Check the Water Pressure on Your Combi Boiler?
The water pressure in your combi boiler should be between 1 and 1.5 bar. If the pressure is too low, the boiler may not function correctly and may not be able to provide hot water or heat. If the pressure is too high, it can cause leaks or damage to the system. Checking the water pressure regularly can help prevent these problems and ensure that your combi boiler is functioning properly.
How to Check the Water Pressure on Your Combi Boiler
Checking the water pressure on your combi boiler is a simple process that you can do yourself. Here are the steps to follow:
Locate the pressure gauge
The pressure gauge is usually located on the front of the boiler and looks like a small circular dial or digital display.
Turn off the boiler
Before checking the water pressure, you should turn off the boiler to avoid any accidents or damage to the system.
Check the current pressure
Look at the pressure gauge to see the current water pressure. The pressure should be between 1 and 1.5 bar. If the pressure is too low, it may be necessary to add more water to the system. If the pressure is too high, you may need to release some of the water to bring it back to the correct level.
Add or release water if necessary
If the pressure is too low, you can add more water by opening the filling loop valve. This is a small tap or lever that is usually located near the boiler. Open the valve until the pressure gauge shows a pressure of 1.5 bar. If the pressure is too high, you can release some of the water by using the pressure relief valve. This valve is usually located near the pressure gauge and should be opened slowly to release the excess water.
Turn the boiler back on
After adjusting the water pressure, you can turn the boiler back on and check that it is functioning correctly.
What to Do If the Pressure is Too High or Too Low
If the water pressure on your combi boiler is too high or too low, there are several steps you can take to fix the problem. If the pressure is too low, you can add more water to the system using the filling loop valve. If the pressure is too high, you can release some of the water using the pressure relief valve. If you are not comfortable adjusting the water pressure yourself, you can hire a professional to do it for you.
It is important to note that if you are experiencing persistent low or high water pressure, there may be an underlying issue with your combi boiler. In this case, it is recommended to contact a professional to diagnose and fix the problem.
Conclusion
Checking the water pressure on your combi boiler is a simple process that can help prevent problems and ensure that your boiler is functioning properly. The water pressure should be between 1 and 1.5 bar, and if it is too high or too low, you can adjust it using the filling loop valve or pressure relief valve. If you are experiencing persistent low or high water pressure, it is recommended to contact a professional for assistance. By regularly checking the water pressure on your combi boiler, you can help ensure that it is functioning efficiently and providing reliable heating and hot water for your home.
