Whenever the home boiler happens to lose it pressure, the proper heating of the home using it will be compromised. A solution must be reached as quickly as possible to ensure that in the event that it loses the pressure, it doesn’t take too long to restore it. The good thing, however, is that it won’t be absolutely necessary that you seek the help of a professional. You can re-pressurise your boiler by yourself very quickly. There are two ways you can use to do this depending on the type and age of your boiler. The first method is by adding water using the filling key. Alternatively, it can be done through the opening of the water filling valves. Here’s how to go about the two ways:

Using a Filling Key

In this method, the process can be undertaken with the following procedure:

Step 1: Turn off the power to the heating system

You need to turn off the boiler and let it cool for a few hours. This is necessary to avoid hurting yourself or damaging the system. Waiting for 4 to 6 hours before proceeding with the other steps is recommended.

Step 2: Pull out the Tray

Once the boiler has cooled properly, you can reach your hands under it and pull out a tray that’s hidden underneath it. This tray may be made of plastic for the newer boilers. The older ones may have trays made of metal. Despite the material from which it’s made, get it out of the boiler in a gentle manner.

Step 3: Get the Filling Key from the Tray

The moment you pull the tray from underneath the boiler, you’ll notice a piece of metal or plastic shaped like a key that’s attached to it. This key is often secured using a clip on the tray. Once you notice the key, pull it out gently from the clip.

Step 4: Place your Key into the Keyhole manifold.

Next to the manifold nut, you’ll find the manifold keyhole. Gently slide the filing key into it and then turn the filling key to the unlocked position.

Step 5: Rotate the manifold nut Anticlockwise

Here, you’ll need a wrench to gently and slowly turn the manifold nut in a counterclockwise fashion. Water should be heard moving into the boiler once you’ve turned it halfway and this should cause the pressure of the boiler to rise. Once you notice this, observe the pressure gauge and turn the nut clockwise when it reaches 1.5 bars. If the pressure goes too high, use the nearest radiator by turning its knob. After this, put back everything the way it was and set back the heating system. Then, turn the boiler on when through.

By Addition of Water an Using the Filling Hoses to Raise Pressure

Step 1: Turn off the Boiler

The first step is to turn off the boiler and then waiting for between 4 and 6 hours for it to cool down completely.

Step 2: Ensure the Filling loop Hoses are Attached Properly

Make sure that the hoses are attached properly and are tight. If they’re loose, they could be the cause of the falling boiler pressure.

Step 3: Open the Filling Valves

To open the valves, you’ll need a screwdriver to turn them counterclockwise. When this happens, cold water will be allowed into the boiler. Water should be heard flowing.

Step 4: Close the Filling Valves

When the pressure gauge reaches 1 bar of pressure, begin to close the valves. The comfortable range of pressure should be between 1 and 1.5 bars. When it reaches this reading, turn your boiler back on.
