Radiator valve/pipe leaking - need advice

[GoodOne]

Hi, my radiator valve/pipe is leaking (you may refer to the photo, the arrow indicated the leaking point) i am seeking for an advice before i can start to diy. I hope with this diy, it does not require me to drain the system. Is it possible not to drain the system?

Btw, I have tighten it.

Kind Regards,
Harman

If it won't 'nip' up, then the joint needs to be split and remade, ideally.....although you maybe could get away with undoing the nut, pulling the pipe down and wrapping PTFE around the olive before replacing it and trying again.
A drain down is needed though - or depressurising the system if its a combi.

We got a storage system. Any guide/advice for drain down?

Storage system?

Or freeze the pipe.

 

[GoodOne]

that is what i meant by storage system.

Bung the expansion tank and get a wet vac to hand.

PS I love the 'arrow'

How do i bung the expansion tank? Do you mean drain it down?

As BURNERMAN alluded to .... If you a small cold cistern (F&E) in the attic, alongside the larger main cold cistern, then you'll need to isolate/tie up the ball cock in the F&E tank and bung up the pipe at the bottom of the tank as HERTS mentions, turn off the radiators and open that fitting until the water stops. Depending on where the rad is this could take a while.
If you don't have the small tank then it's a sealed system, then it's turn the rads off and crack open that rad vent until it stops, turn that rad off and crack the nut and catch any other water until it stops.

If you're at all unsure then call in a professional, much simpler in the long run.

I was told that i got a gravity system. To drain it, i need to the off the (arrow show on the image)?

Have you two water tanks in the loft?
If you have, it's the smaller one you are interested in.....close off its water feed, stopper it's outlet if possible, and then you can start draining.

That valve has nothing to do with draining the CH, that's probably the gate valve that isolates the HW cistern from the large tank in the attic.

If your comfortable doing it... .... then find the small tank in the attic and follow the instructions.... , if at all unsure, call someone...

OK will go up the attic tomorrow morning to check if there is a small tank.
