HELP! Radiator cold at top bt has not bleed valve!

Are you certain it hasn't got one? It'll be a first for me.

I can see the only solution is to replace it with one that does have a bleed valve.

Then you need to fit a bleed valve to it!

You cant find a bleed valve to a radiator?

And i wa shoping for a suggestion that didnt mean fitting a new raditaor!

Yeah its a single planel one...i also didnt know some radiators didnt have valves...I also have one in the bathroom.

There Must be another option?

definately not on the back of the radaitor? as you look at it from the front, top right on the back.

The old house i used to live in had single panel radiator's and each had a very small little screw on the back. Which, in my case, had been painted over many times and took a good while to free off!

Nope!,

Its also abrand new radiator...

Have you looked on the face of the back panel? Some rads don't have "proper" bleed connections to the end of the top rail, but have a small nipple on the reverse face of the top rail (IYSWIM).

The ones in our office are like this, first I've seen like it!

Every radiator I've seen has either a bleed valve in one end, or on the rear face, near the end, or was supplied with 1/2" BSP holes at each end, so you could fit a blanking plug in one and a plug with a bleed valve in the other.

Does yours have two blanking plugs, or evidence where a bleed valve has once been (but has been, say, broken off, or bodged over)?

I found it!

man i am dumbass

thanks

The message from marc snipped-for-privacy@hotmail.com contains these words:

It's not one of these that have the bleed valve hidden on the back edge instead o in the endcap?

Aye. They are sometimes hidden behind a smooth plastic cap on the back edge rather than in the ends. Probably can't see the cap but run your fingers along the rear and you may find a slight bulge.

The message from "Marc" contains these words:

Well, come on then show us a picture!

In the unlikely event that it doesnt have one, it will have provision for fitting one. In the even more unlikely event that it doesnt, drill and tap a small hole and insert a small SS machine bolt, say M4, with a slot filed at an angle in the thread in the bottom half. Now this can be unscrewed half way and let air out without the screw coming out.

I can't imagine any radiator not having either a bleed valve or the blanking plug where a standard bleed valve would go. Making one without such provision would render it nigh on useless.

Since the OP's rad is nearly full of water, we can conclude it must have a bleed valve - how would it have got full otherwise?

NT

No radiator I have ever seen has not got at least the OPTION of fitting a bleed valve. They are essential on ALL radiators.

At the least you normally get a plug at each end with a square recess in it that enables you to unscrew it and fit a bleed valve.

Yup! Where was it?
