Why Does Your Boiler Pressure Keep Dropping?

The normal pressure for boilers should be between 1.0 – 2.0; you can check if yours is the correct pressure by looking at the pressure gauge that should be installed. Low boiler pressure is not always something to panic about; often you’ll just need to re-pressurise the boiler and it’ll start working again. However, if your boiler continuously drops in pressure, there may be a more serious problem. There are usually two main reasons for pressure dropping in your boiler.

Leaks.

One reason your boiler pressure might keep dropping could be because you have a leak in your boiler, pipes or one of your radiators. Leaks aren’t always noticeable as they can be very small. Start by looking around your house for any damp patches that may indicate that there is a leak somewhere. If there are not any visible leaks, there could be a leak inside your boiler. Always call in a professional to look for leaks inside your boiler or to repair leaks you have found, as DIY repairs can end up costing more money.

Radiators.

Have you recently bled your radiators? This could be the reason why your boiler pressure has dropped. When you bleed your radiators, you’re releasing air from them which then lowers the pressure in your boiler. This isn’t necessarily something to worry about, however if your boiler starts to drop in pressure regularly, it might be time to call a professional in. Only ever re-pressurise your boiler yourself if you know exactly what to do.
