It'll take longer than a couple of seconds. If you can hear water going in you're on the right track.When I turn the silver pipe valve it sounds like water is filling it up but the pressure gauge doesn't move? I turned it off after a couple of seconds as was unsure whether I could be damaging it. Does it take a while for the pressure to increase?
How would I know if the others are closed? Should they be turned towards me or should they be turned to the side? Sorry I'm a complete novice at anything like thisUnless you’ve closed any other valves off under the boiler, it should be relatively quick, unless your mains water is poor pressure?
Yes it worked before and the CH was fine, just needed to bleed radiators as tops were cold and bottoms were hot.Did the gauge work before, was the needle up around between 1-2 before you bled the radiators??
Ok will try this. Should all the other valves be open? Or should some be closed?Are you turning the lever fully,until it comes to a stop ? If so ,try turning it partially back ( To less than fully open) that will reduce the flow ,will take a bit longer to increase the pressure ,but may reduce the shaking.
No I don't think they have. They are aligned with the pipes so that means they are all open right? I know you said it will take longer with only turning the valve a little but roughly how long should it take?Have you altered any other valves positions ? If you have not ,you don't need to worry about them ,they will all be open.
