You should take the original float valve to a decent plumbers merchant and source a new one with a suitable length tail,and forget the faffing about with washers. Also take the seal from the isolation valve ,and get a suitable replacement.

Correct ,and believe it or not 1/2 inch BSP thread is nowhere near 1/2 inch in diameter ( it's nearer 3/4 of an inch) !!

The pipe size is irrelevant, only the thread of the float valve and the isolation valve needs to be the same.

The thread of the valve tail in your picture looks like 1/2inch BSP to me. The 15mm measurement in the pdf drawing would appear to be nonsense, having never seen a float valve thread with a 15mm diameter, as it appears to depict.

Your measurement of the threaded tail doesn't include the thickness of the cistern or the seal inside the cistern. You will very likely find that your new valve will fit without needing to cut it at all. There will be a seal between the isolation valve and the threaded tail of the valve,and you...

Just fit a complete new float valve.

Close every other rads TRV,don't touch their lock shield valves,run heating and see if the non working rad now heats up.

As above ,you will likely need to extend the pipework. A TRV with a union fitting ,rather than the compression fitting yours has, may allow you to fit it without amending pipework.

Just turn the black handle ,the pressure gauge next to it should register the pressure. If the boiler error message doesn't clear and the boiler start to function,you would need to use the dial to reset.

Show us a picture of your new TRV ,it may be a straightforward swap.

Show us a pic of the other end of the silver Flexi pipe/ what it connects to. It is very likely your filling loop.

Some of the copper conductors are sticking out from the terminals ,there should be no visible copper. The red wire is hanging out of its terminal. You shouldn't unscrew the switch plate from the mounting box with the power on either !

Push the seal back into the boss ,see if it is then watertight/ free of leakage. If it is the white waste pipe needs support to prevent it from pulling outward from the boss.

Somebody has, there are new and old versions of the wiring colours present.

Engage an electrician,your existing wiring shows a black wire connected to an earth terminal and needs investigating by somebody qualified.

You need to establish exactly where the leak stems from. Is it the union that connects the valve to the rad,or the valve to the supply pipe,or is it from the valve body ?

Time to call in a plumber ,your pump may not be circulating water.

Is the pump spinning ,is its body exceptionally hot ?

Are all upstairs radiators heating up fully ,or only warming ?

That is a hot water cylinder. I assume you have a programmer that allows for the boiler to heat the water in the cylinder and / or the central heating ,set that for central heating only.
