Leaking radiator after bleeding valves

[awz1]

Hi everyone,

I was wondering if someone could provide me some advice. Due to high boiler pressure, I bled some of my radiators. However, one of radiators is now leaking on both sides from a nut at the spindles?

Could some explain to me why this happened and what I can do about it? I’m assuming just use a scanner to tighten both sides up.

Any help appreciated

Do you mean the big nut between the rad and the valve ?
not sure what spindles are
centralheatking

 

[awz1]

Yes I mean the big nut.

Sorry wrong terminology. Will it be a simple job of using a spanner to turn the nut, on both sides of the radiator

 

[Rob Foster]

Thats plumbing for you. yes it should be simple as you say. But if you are dubious turn off the valves first then only the contents of the rad will escape.
centralheatking...lets us know
how it goes.

Actually no! Don’t just get a spanner and tighten that nut. Get another spanner or pair of grips etc to hold the pipework still as you tighten the nut.

How high's the boiler pressure?

 

[awz1]

About 2.5

I have been trying to get it down, am waiting for someone to come and have a look. That is why I was doing the bleeding of the radiators. Would there be a link between high boiler pressure and the leak?

There was no leak previously despite the high pressure, it just started after I bled the radiator. This only happened to the upstairs radiator and not the downstairs

Many thanks

Where did you bleed the radiator from?

 

[awz1]

The bleeding valve. I have a key which I used to turn the radiator valve and took the water out.

The pressure is now decreasing, I think someone did not close the filler loop. It’s at about 1.9 now after I have moved the lever. The leak however persists in the nut by the thermostat
