    I recently moved into a new house which has a Worcester greenstar 34 CDi classic combi boiler, which has a keyless filling link.

    I tried to top the pressure up by using the blue lever, but when I do water starts to come out of the back flow relief port (out of all 3 holes). So the only way I can re-pressurise the system is by covering all the holes and pulling the lever at the same time - which makes the easy to use keyless filling link not so easy to use.

    Is this normal or is there a reason water is coming out of the back flow relief port?
