If your boiler pressure has dropped too low, it can cause it to stop working properly, leaving you without heating or hot water. Luckily, re-pressurising your boiler is often a simple task you can do yourself, saving you the cost of calling a heating engineer. Here’s a quick guide to help you get your boiler back up and running.
Step 1: Check the Pressure Gauge
Before you start, take a look at the pressure gauge on your boiler. It should be within the green zone, usually between 1 and 1.5 bar. If it’s below 1 bar, you’ll need to re-pressurise your system.
Step 2: Locate the Filling Loop
The filling loop is a silver hose with two valves, usually located underneath your boiler. If you’re unsure where it is, consult your boiler’s manual or call us for guidance.
Step 3: Open the Valves
Gently open both valves on the filling loop. You should start to hear water filling the system, and the pressure gauge should begin to rise.
Step 4: Monitor the Pressure
Watch the pressure gauge closely as the pressure increases. Once it reaches the ideal level (around 1.5 bar), close both valves tightly. Be careful not to over-pressurise your system, as this can cause further issues.
Step 5: Check for Leaks
After re-pressurising, take a moment to check for any visible leaks around the filling loop or the rest of the system. If you notice any, it’s best to give us a call to inspect and resolve the issue.
Step 6: Reset Your Boiler
Many modern boilers will automatically reset once the pressure has been restored. If not, you may need to press the reset button on your boiler to get it working again.
If you’re unable to maintain the right pressure, or if your boiler keeps losing pressure, there may be an underlying issue, such as a leak or a problem with the pressure relief valve. In such cases, it’s best to call a qualified heating engineer like ourselves.
