Knob sheered off!! What can i do?

[Alex evans]

So. This knobby bit sheerd off. Unfortunately, its stuck in the closed possition. Meaning all my other rads are toasty, while this one is freezing.

What can i do? :/

Time for a new valve if you can't grip the bit that is left.

Cant grip it at all. .... Cant i juat glue the fecking thing back on?

No, unless you can undo the gland nut and manage to grip the shaft with water pump pliars, you need a new valve.

It looks a mess. Whilst draining the system it would be a good idea to replace any others like that.

Even better to replace hem all!

but it will break again eventually so might as well change it , and do others at the same time . saves time in future if you have a related problem with your heating system

As a quick fix so im not cold tnight. And have a plumber in as i need a service on the syatem anyways. I got some of that horrible gorrilla glue, worth a dab?

If solid brass has sheared off then no glue will allow it to turn when so seriously seized up.

TBH , if its a temporary fix then try it it could work ( needs to be strong enough ) but i wouldn't leave it like it , if you had other problems in future it could become a ball ache and cost you more .

Ive put some on. Now ive put a cover, just a small dab on the outside of the sheer. Will report back after ive tryed to move it. Il let this dry for a few hours.

It will never work!

Even solder would not work either.

Brass already sheared off and it needs to be stronger.

Try replacing with high tensile steel.

what have you applied ? most products won't be strong enough i doubt

 

[Alex evans]

What if i took the nut underneth it off, so i could then Grip more of the niplle. But woldnt water gush out?

 

[Dan Robinson]

Some. But it should be manageable. You need a new valve though.

On the basis that you think glue will work, there's not much point in suggesting you drill a 3mm hole down the spindle and use a screw extractor to turn the valve (anticlockwise) to open it. Something like this : https://www.machinemart.co.uk/p/cht526-12pce-drill-screw-extractor-s/
