Boiler inlet valve

[North]

Hi all,
My boiler top tank is getting too much water from the inlet and is all getting out through the relieve pipe to my garden.
The boiler tank is located in a cupboard where I am unable to see inside the top of the tank as it is too close to the ceiling and I can barely stick my hand into it and touch the floater and the inlet pipe.
I am not an expert but the system seems very similar to the old toilets with the floater closing down the water inlet when there was enough water in the tank. In those cases there was always a screw which you could regulate in order to have more ore less water in. Is there something similar in the boiler tanks to adjust the volume of water in the tank? And if so how can I stop the overflow?
Many thanks

this is what a plumber calls "a pain in the a**e"

you will need a new ballvalve (similar to that in your toilet) or possible new washer.

the reason this job is difficult is because of where it is as you sad yourself its practically unaccessible the plumber who put it there wants shootin he should of allowed enough space for maintainance

anyway changing the valve will be easier than changing the washer and you will have to work "blind" i imagine this would be difficult if you dont know what it looks like.

it will be a difficult job and you will scratch the s**t out of your arms trying to work up there

if you can afford it get someone to do it for you i would charge around £85 for new valve

sod that, siphon the water out and remove the complete tank. then work in ease and comfort at floor level.

Thanks a lot for your views. I do not think I will have space enough to fiddle around with my hand and install anything even though my hand is rather small . I think the option of siphon out the water of the whole tank, bring it down to the floor and install the new valve is the best option.
I will have to try that.
Many thanks,
North

assuming this is not a wind up: Nickso was tking the pi55. From your comment: water of the whole tank I guess you have a rolyat type ombination tank. If so, don't even think about removing it. Is this in a house or flat? If your loft is immediately above the tank, you could consider cutting a square hole out of the ceiling, after sliding a cover above the tank, in order to gain easy access. Afterwards, create a trap cover for future access.

To clarify: I live in a house (so no neighbours below) and i have one of these boiler tanks with the cold water tank above feeding the hot one (all in one single piece).
What is wrong in emptying the tank and bring it down to the floor? I do not like the idea to deal with the pipes attached though. The idea of cutting off a square bit of the celling right above the tank also occur to me but I have the loft floor coverted with wooden planks so it is also a lot of work. Not quite sure what to do now...
