Radiator outlet pipe dripping

[jchannon]

I have a radiator that has a pipe outlet for draining the system, not sure what the technical term for that pipe is but see attached picture. Anyhow it appears to be leaking occasionally. There seems to be a puddle on the floor in the morning by the radiator.

Can anyone suggest what is wrong?

It's leaking and needs a new washer.

The actual bit I'm talking about is outlined in a red sqaure in this picture.

Make sure it been done up enough, if still leaking allready said will need new washer

Is the washer just on that bit or is it on the bit attached to the radiator?

On the bit you have outlined check the small square "nut" to the right is done up tight. If it still leaks unscrew it using the nut pulling it all the way out of the fitting and you will see the washer. This will drain the system so attach a hose or catch the water in a basin etc.

Thanks. Will it drain the whole house or just that radiator? Is there a technical term for that bit of pipe?

 

[denso13]

Unlikely to be whole system. If you close off all the other rads you may not get much water coming out at all. Just be quick

Excuse my ignorance but to shut them off do I just set the TRV's to 0?

 

[denso13]

Yup

Thanks for your help. Out of interest why do you think it only leaks sometimes overnight?
