plumbing question for the experts(copper pipe)

[Huntindad]

I had to replace a toilet and found out I needed to replace the water intake turn off valve.
I pulled the old valve & the compression sleeve and nut are still on the copper pipe(5/8’s)
I tried to re-use the sleeve with the new valve… it leaked.

I’m thinking my 2 choices are…

Get a sleeve puller and remove the compression sleeve. Lightly sand the copper pipe and replace the sleeve with a new one and re-assemble the valve. Or
Sweat a fitting onto the copper pipe.

From past experiences… will the copper pipe be usable to put another compression ring on ? Or do you think it will be too deformed from the old one? The pipe sticks out only a inch or so from the wall.

I’d rather not use the torch if I can help it.

Thanx,

David

I had a friend use JB weld in the same senario you have. He had wood like bat and board style half way up his wall and didn't want to sweat a new fitting either. The JB weld still doesn't leak or at least the last time I used his bathroom it wasn't anyway. Been 2 years now.

I would try wrapping some Teflon tape around the threads and then reassemble. I put tape on everything that has to do with plumbing.

He's probably not leaking at the threads but on the backside of the compression nut.

It's a bad deal. With only an inch to play with you don't have any good choices.

I suspect that by the time you get the old ferrule off the tubing will be too messed up to do a new compression fitting but that would be the first thing I tried. Make sure you clean up the pipe good with a very fine grit emory paper.

If the compression fitting still leaks you can clean it again and try a 1/2 X 3/8 "push-on" valve (similar to the sharkbite connections). They use a rubber gasket to seal and might be a little more forgiving than the compression fitting.

With your situation the only thing you can do is put on another compression valve.

The brass ferule squeezes into the copper tubing so removing it and trying to solder a new valve on will probably not work and I doubt you would be able to reinstall a new ferule and compression nut over the distorted copper pipe.

The ferule will not leave enough room for any type of slip on valve.

Teflon tape is not the solution either.

If you hold your mouth right you should be able to replace the compression valve with a new one while reusing the old compression nut and ferule.

Only option I see with the limited length of copper tubing visible is to cut a hole in the wall and sweat out the copper pipe in the wall and reinstall a longer piece of copper and new shut off valve.

JB Weld may work as well but that is not a professional type repair I can recommend.

You can usually reuse the compression nut and feral. I'd try a different anglestop. If you bought the valve from lowes or ace it's likely to leak. We have had bad luck with certain brands of anglestops dripping around the compression nut. Some parts are just junk. If all else fails cut it off and install a new one. You really need at least 3/4" of copper to tie on to so you might have to cut the pipe with a hacksaw right behind the nut to save every bit of copper if it's too close.

And will quite possibly lead to a you might be a redneck joke... it did for my buddy.

thanx for the ideas folks... another question.

Could I (real carefully) use a hack saw or dremmel and cut the compression sleeve off the pipe. That way it would not damage the pipe trying to slide it off.

[Sparkles]

I would think try may be key word here. I would suck to get into the copper and have open the wall up to add more pipe.

Like said, if you have enough room, cut the copper with a mini hacksaw right behind the compression nut. Try and solder on a 1/2" male adaptor then use a 1/2" IPT brass angle valve. Next time you need to replace the valve all you have to do is un-screw it.
If you have any issues with water in the line try pushing some bread into the line then solder adaptor and install valve. Put your supply line on valve and flush bread out of the line into a pan/can/whatever and then connect to toilet.

You can sometimes get away with that method. Then solder on a male adaptor.

You can use the EdO method developed after many years of wrestling with plumbing problems. Call a plumber and let him worry about it. For some reason plumbing always turns into a lot bigger job that it appears on the surface.

When dealing with water and plumbing don't take the easy and cheap way, you would really be mad when you come home to find that you have had a water leak spewing for a day because you tried a method to save $20.

That's a fact

the 5/8s is actually 1/2". 5/8 is the refrigerant size. Get new hardware and re-install. Love the torch. My opinion
