Bathroom radiator won’t heat up/manual valve

[exedon2]

I see you indicated the return valve needed 2 1/4 turns before water came out that would be my main suspect.
I've seen some of the cheaper types of the rad valves like yours have non rising head works that can jam fully open or virtually closed.

Hi, the reason we took the radiator fully off was so that we could see sideways into the valve. We could see that when turned the valves were opening and closing. The valves were atleast £30 so I wouldn’t say that they were cheap…

Turn all the other trvs off and retest does that one heat up ?

Hi, someone already suggested that in the message chain above it didn’t work.

Piping to the rad faulty if your getting flow from each side so never worked

Hi, sorry don’t know what you mean. Can you explain abit better. Thanks

Sometime has to be wrong with the piping your getting good flow out of each valve

Rad is changed / clear

So sounds like the pipework is wrong eg flow to flow or return to return

The radiator did work and was very hot at one point but just has not worked properly for some reason for several months.

Can’t be as you’ve turned all the others off and it still doesn’t heat being the only one left ?

Hi, as mentioned above the radiator used to work fine, before that radiator was in situ there was a towel radiator that had manually valves and again that worked fine for years. We don’t know if it could be a problem with the pump on the boiler not being impactive enough or potentially whether this could be an indicator of a blockage in the pipe. Or something else.

Your hot water is working ? , all your other rads are working fine ?
Water is flowing good from both pipes

Something else I would say

Hi, yes we have hot water and all the other radiators in the house work fine apart from the one in the bathroom.
