If I remove valve from pipe can I put it back together again ?

[Bob L]

Attached is a photo from the inside of a bathroom vanity cabinet, showing a copper pipe and an attached valve.

I want to remove the valve from the copper pipe, leaving just the bare copper pipe. There is a nut on the copper pipe that joins the copper pipe to the valve. Am I right in thinking that between the valve and the nut there is some kind of compression seal that fits over the pipe so that when the nut is tightened, the seal is compressed and prevents leaking ?

So to achieve a bare copper pipe I would then unscrew the nut, pull the valve off, pull the nut (and compression washer) off the copper pipe.

And to put it back together I would simply reverse the steps. So I would not have to do any soldering.

Will greatly appreciate confirmation (or denial) that this is a correct understanding.

That's how that works
You may need a sleeve puller to pull the back nut and the sleeve off.

Thanks so much for the info, Terry, and for the bit about the sleeve puller. I assume I should probably replace the seal ?

I normally use a new sleeve (ferrule) when reinstalling.

Or to be more accurate, an entire new shutoff.
I don't like using old parts.

Hi Terry: Many many thanks for the advice.

You WILL have to have at least a new compression ring, because the old one will be too small to fit over the pipe again.
