Plumbing Advice - Thermostatic Radiator Valve

Help needed to mend/replace broken thermostatic radiator valve.

The top of the radiator valve has been broken - leaving the radiator running on max heat whenever the heating comes on.

I'll upload a pic to show the damage!

Can I replace this myself of do I need to call a plumber?!

Its not urgent - it just gets a bit warm in the room!

Will really appreciate any help anyone can give me. Cheers!

you can replace that your self, the nut of the head is still on the valve, just unscrew it, then get a new valve and just use the head.

no need to drain the system

Agreed with this guy. the very top silver 'threaded' ring. Unscrew it, should be able to by hand, don't worry, you won't flood the house, and replace, simple. £7 approx. replace.

You do have to get the exact make and model that's already installed or it wont work. You can't mix and match heads with valves. If you can still buy that valve, do as souljacker said.

now googling 'Drayton TRV 4 head'

Actually another radiator doesn't work at all - (it did be before) - tried bleeding it.... no joy. Any suggestions?!
#16
To make it work in the meantime you need to press down that little round rod sticking out the top. If you have a small G-clamp or similar you should be able to do it. May need a small bit of wood under the nut or valve to get something to press against.

Just check if the plunger is working too by pushing it down with a coin, if it moves and returns to its original place it should be a simple case of replacing the head, if it's seized the whole valve will need replacing.

Is a TRV fitted to this rad?

There is indeed. But this one doesn't appear damaged!

Take the head off and check if the plunger isn't stuck down, if it is get some pliers and gently try to pull the plunger up don't go mad with it though.

thats to turn the rad off, it will work fine with the head of and the pin up, no need for all that messing

that was referring to the first rad...keep up (_;)

It does amuse me how some people post in threads when they don't actually have a clue, the reply above and the first reply in this thread...why bother?
