radiator prob

[stelang]

Hi , i have one radiator out of 5 that will not bleed , even when i turn the rest off it still wont play ball. It gets hot at bottom and i can hear the air coming out, but not a lot and only on occasions . When the heating is off i can hear like a dripping sound from inside the rad about 90 seconds apart... It is in the bedroom the rest are ok 5 rads in all problem started about 2 months ago . Im thinking of taking it off and reconnecting it to see if this helps... trapped air ? i dont know........... thanks

not sure what a trv is but the valve is quite big and i can turn it very easy and it is numbered 1 to 5

Yep. That's a trv. Take the plastic head off you'll see a wee pin. Make sure it'smoving up and down.

Don't touch the nuts with the pipes in them. That way ends in tears and your wife shouting rude words at you.....

 

[stelang]

how do you get the cap off ? tried pulling it up and there is no screw holding it on .. its a lifestyle make...

 

[stelang]

it is a solid valve white plastic there is no separate cap to it

 

[PlumbBobBob]

where it joins to the valve is there a knurled ring? you unscrew that to remove it like on this one

Post a photo of it.

[stelang]

yes the pin moves when pushed down and returns

 

[stelang]

new to me this ... did you get the picture ?

 

[Dotty]

Leave the head off for a while see if the rad heats up.

I see you're on microbore which could be a whole other problem.
