i have too much pressure in my worcester boiler, i have tried bleeding radiators, and there are a couple of pipes under the boiler i have tried. it initially goes down, but then it comes back up into the red!!! i dont know alot about boilers and would really like some help before I call a plumber in...
Make sure the filling loop valve is actually fully closing off - that sounds like the real problem. Then, reduce pressure by bleeding through the radiator valves.
