Hole in radiator, possible to fix?

[Ian H]

I just noticed a radiator dripping so closed the valves and it stopped. There’s a hole in it near the valve and i’m wondering what are my chances of fixing it?

It must be on the threaded part with it being so close to the end

Is there a product I could try?

Thanks.

Thinking maybe drill the first bit of the hole bigger, get some of this https://www.screwfix.com/p/unibond-...EyRBVyiyjYvCIKmKIr0aAmkHEALw_wcB&gclsrc=aw.ds and press some in.

New radiator time Ian, make sure you have inhibitor in the system.

Gutted. Time to test the 10year guarantee.

It has Sentinel x100 in it, is that any good?

If its on the female threaded spigot, where it mates with the male thread of the valve tail, you could try some liquid ptfe to remake the tail into the socket and thus seal both at the same time perhaps! Whilst you pursue the warranty claim

I’ll give that a go I did think about injecting some liner resin into it too.

Good luck with the ten year warranty

I don’t even know where we bought it from!!

How do I shut off a TRV?

Remove the head, "fit a decorators cap" and cross your fingers! Or screw a female end of a suitable size in place of the rad.

just turn it off

Remove the head and cross your fingers!

Removing the head of a TRV will leave the valve wide open! TRV's are supplied with a service cap to be fitted to close the valve to allow the rad to be removed. If you haven't got it, turn the TRV off and hope for the best. I know someone who took a rad off, think the TRV was shut, as the room cooled down the TRV slowly started to open.....

Er yes forgot about the decorators cap, paying attention to tv instead of typing, multi tasking is not working well tonight, make sure you screw that on firstthanks!

Only way to fix that is to drain, dry and weld/braise. Know anyone local that can weld cause that will take 2 secs and 2p of time to do.

I think you might be right.

I took the valve off today and I think the threaded part is an insert into the steel tube that’s the radiator bottom.

The weld must not be good all around the insert. I’ve sealed it in and out for now and if it leaks again i’ll get it welded. I’m pleased it’s not corroded.

I think the leak comes through like this:
