Why does my boiler pressure keep going down?
If your boiler pressure keeps dropping, give your engineer a call to avoid any further damage to your heating system, or worse, your lovely home. Causes for consistent drops in boiler pressure could be a faulty valve on your boiler or a leak.
When do you know if your boiler needs to be replaced?
On most digital gauges, you’ll see a flashing pressure reading, if there’s a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced. This is where that filling loop (or filling link) comes in again!
Can a leak in a boiler cause pressure loss?
Whether you have an oil, system or combi boiler, pressure loss is usually directly related to a leak in boilers. We’ve already created a guide on why boilers leak and how to find leaks here. Most boilers operate at 1.0bar-1.5bar. But they can approach 3bar if there is a problem like a leak.
How can I tell if my gas boiler is low or high?
If you have a hydraulic pressure gauge, you’ll see low and high pressure indicated by red sections on the dial. The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you’ll see a flashing pressure reading, if there’s a low (or high) pressure warning.

What should I do if my boiler pressure keeps dropping?
To fix this, you can pressurise your boiler by topping up the system via the filling loop. However, if your boiler pressure keeps dropping, chances are you may have a leak. Boiler losing pressure – what pressure should my boiler be?

Why does a boiler need a certain amount of pressure?
Boiler pressure is simply the balance of water and air within your boilers sealed system. In order to function correctly, your boiler needs a particular balance of water and air to ensure the pressure in the system is adequate for when water is demanded from the boiler – essentially when you switch on your heating or hot water.
Why does my boiler lose pressure when I Bleed The Radiators?
Remember if you are constantly removing air, the pressure will drop each time you bleed the radiators. Every now and then expansion vessels will need to be repressurised. If they are not, they can affect the pressure of the boiler. In some cases, the boiler losing pressure could be for this very reason.
