Plumbing Question

Fitting a bleed valve to a radiator

One of my radiators doesn't have a bleed valve on either end and I want to fit one. Is this a simple enough DIY job that one of you can step me through or will I have to get someone in? Many thanks.

I'll have a look at the back of the radiator, but I had a plumber in a while ago who couldn't find one anywhere on it. My house has a bit of a strange history so I'm not entirely surprised by this although from your responses it is quite unusual.

I never seen a radiator without a bleed valve, you will find that you have the make of radiator which has them fitted at the back of the radiator , feel for a little plastic dome or pimple and pull out the plastic cover.

All radiators are either factory fitted with a blede valve, ( please look on the rear of the radiator ), or otherwise supplied with, then fitted by the installer, a 'blank off' for one end and a 'bleed valve' for the other.

Either, the installer has got it wrong ?

I.E. installing ' blanks', at either end,

Or please look again !!

Do the radiators have round tops ?,

If so, please look again, at the rear of the radiator & you may well see an air vent.

Well all you will need to do is drain down the radiator turning off both radiator valves first then simply change the blank for a bleed point
