Copper pipe crushed by olive reusable?

[gravamen]

Hi guys, grateful for any help you can offer. In lifting and relaying a floor (insulating subfloor and strengthening with noggins and sistering...), I've had to remove the radiator valves to get the floorboards up. When I took the valves off and cut the olives, I've found the olives have crushed the pipes.

So can I refit the valves to these pipes? Should I use Fernox? PTFE? Or do I have to cut and solder a coupler? (less popular option with me, obvs)

Should be ok, use copper olives with a bit of paste

I'd lose those ends and solder in a coupler, personally.......they have seen better days!

Cut and solder in new piece for each. I wouldn't take the risk of using the one in the first picture, and I'd almost guarantee the one in the second picture to leak.

Agreed! I've sealed up worse than that!

Splurge on a wrap of PTFE

Dry though.

A dry fanny's no use to anyone.

If thats the only way you can get em wet, thats fair enough

Thanks for all the help guys! This is why I love the site. At least half the people will tell you that what you're doing is okay. Have PTFE'd them and repressurised and they're holding fine and passing a tissue paper test.

Are they likely to develop leaks at a later date or is it a case of "if it holds at first, it will hold for good"? (He asks, hopefully... )

If it holds with PTFE it will forever. Old skool Hemp and paste will "take up" a weep as the hemp swells so it'll hold forever and a day BUT it grows micro organisms so isn't used now God knows how us old plumbers survive so long what with lead and asbestos and no PPE back in the day

Well I certainly would not use that end of pipe again, defo a potential leak in the offing.

1: Nice if their was an internal pipe expander to 15mm OD but there isn't that I know of.

2: Solder fitting if its a fixed pipe I don't see the problem in a normal property, just being lazy.

3: Use no flame situation. a; compression or placky push fit (ugly) b: push fit as in Tectite - Cuprofit neater no flame.

I have found straight compression chrome extensions in 8 and 10mm which work really well with fixed pipes on retro twin valves. Though I am experimenting with 15mm ones made from rad valve tail extensions, just to get that extra length without to much faff if you see what I mean.

And the other half were being serious.
