If you suspect your boiler is not working properly, there is a good chance it is the result of low pressure. If you take a look at the pressure gauge on the boiler the pin should be between 1 and 2 bars; if it is below one then the boiler pressure is too low. There are a few different reasons for low pressure; some can be corrected on your own while others may need an expert to repair.
The number one reason a boiler loses pressure is leaks. The leaks can occur in a few places including your pipes, radiators or the boiler itself. Smaller leaks can be hard to spot, but you can look around your home for damp areas. If you suspect the leak is in the boiler itself then you will need to call in a professional to take a look.
Another reason a boiler can lose pressure is a faulty pressure release valve. If you have a defective valve, it may be releasing too much water which causes the boiler pressure to drop. If you suspect your low pressure is the result of a faulty valve, then you will need to call in a professional for an assessment.
A malfunctioning expansion vessel may also be to blame for low pressure. When an expansion vessel is not working correctly, the pressure will increase causing the boiler to release too much water that will result in lower pressure in your boiler. You can call a professional who can re-pressurize the faulty vessel, or they may recommend a replacement.
If you suspect your boiler system is being affected by low water pressure, you should call an expert to take a look who can quickly identify the problem and make the necessary repairs to prevent the issue from becoming a significant issue.
