Tiny cut/nick in 15mm copper pipe by accident, is it ok?

[robodelfy]

I was just using a Fein tool to cut out a rotten floorboard, I assumed the pipes ran deep as they did for the first metre, but then they came up right under the boards!

The nick is tiny, maybe quarter of a mm, it's impossible to measure.

Is this still ok? Is there a way to repair it or do something to make me sleep better at night

Photos uploaded. I sanded slightly to see the nick better

Better safe than sorry, solder a patch on both ,are they 15mm pipes ?

Yeah 15mm pipes. It's for a bathroom radiator.

I don't have the tools to solder anything. Could pay a plumber £60 to come out and do it, but seems a bit excessive!

I have quite a few speedfit fittings under my floor anyway, should I just put a speedfit straight coupler on?

Upto you how you do it ,Advised the easiest and quickest way ,without having to drain system . You could consider buying torch and flux and solder ...invest in the future !!

Solder on a patch without draining the system? How would you get sufficient heat into a pipe filled with water? I'm sure you know that but the OP might not.

I agree that soldering on a patch or a sleeve would be the best option though by far. Its easy to do and a blowtorch, solder and flux will cost you much less than £60.

self amalgamating tape. I'm not sure I'd drain the system for that.

Yeah I kind of wish I had now, but this is the last part I need to do, so I think I'll save it for the next job!

Draining the system isn't an issue.

But just to be clear, a small nick like this could cause issues if left as is? It seems so shallow, but then the pipe is only 0.7mm thick

Thanks I just looked it up at screwfix, seems like it's mostly for hoses. Is it safe on copper pipe? I don't have a leak,do you think it would really help this nick from turning into anything worse?

Just hard to imagine tape doing that

How would you do that when both pipes are close to each other and sat on a joist ? Not so easy.

I would drain and put in a socket or at least a solder patch. If you really do not want to and "feel lucky" you could try something like this as it is only damage not a leak.

Amalgamating tape....don't even go there.

Drain down, cut out pipework etc, refill with inhibitor (£15)...

Could bodge it with these but you'd need a heat mat under the pipework or cool gel on the joist.

A pre-soldered copper repair patch from screwfix is £4, a blowtorch £20 and flux about £3.50. You can repair both pipes for less than £30 and have peace of mind thereafter....

 

[terryplumb]

Why would you not want to do a proper repair ? The damage may never result in an issue ,but repairing it properly is a no brainer.

I guess I'm just wondering why not use a couple of speedfit straight couplers as I have them elsewhere under the floor. And as it would be my first ever soldering job, I feel like the speedfit would be more trustworthy don't you?

Yeah you're right, just trying to decide between speedfit straight coupler or buying all the things I need to solder these two joints, and learning how to do it.
