Copper Crimp Leak

Hello again,

Today I found a very slow leak in the T shown below. Is there an easy fix?

That is PEX type tubing.
You would cut the three crimp rings off, replace the copper tee and recrimp three new rings on.

The board is in the middle of an attachment issue.

I'm temporarily hosting pictures until the board is repaired.

If you have the PEX crimp tool needed, it's not hard to fix, but takes a little experience to get it right. You might be better off replacing this with Shark Bite fittings.

After removing the light I was able to get at it better and discovered it's not the T.
The leak is coming down a vertical pipe that goes into the upper floor.
Yay

That looks like Quest tubing, not PEX. It is no longer manufactured and does not use PEX fittings or rings. You can use PEX crimpers but because of the slight difference in size between PEX and Quest the tool needs to be adjusted to create the proper crimp. If you find a leaking fitting connection you might be lucky and can just re-crimp it.


Unfortunately Quest has a notorious reputation and it's no longer permitted. Old can remain but if you have to work on an area I recommend removing all of it you can. You can buy transition kits that include a fitting to convert from Quest to PEX and each kit includes a bare copper Quest crimp ring and a blackened PEX crimp ring.

It looks like the water is leaking down from somewhere above. Since nothing has corroded, tarnished or mildewed it looks recent.

Still, I would replace every bit of Quest tubing in the area I was working.

Hi Guys,
Here is where I'm at today. You can see in the picture that I have accessed the pipes from the upper floor.
But there is NO water anywhere. As far down the left pipe as I can reach, it is dry.
I looked down the hole and see no sign of moisture.
The only thing left is the plastic grommet where the pipe passes through the floor. And there's only one way to check that, right? Remove the pipe.
But I am not familiar with the copper to plastic fittings they used (plenty familiar with sweating copper) so I have a question.
If I cut the ring off, will 1/2in tubing fit on it or is this something special?

The bent Quest nipples attached to your faucet cannot be reused. The only pipe that fits them is Quest which you currently have. If the nipples can be removed you can install standard fittings in the faucet body and then connect copper, PEX or CPVC water piping.

That might make this a little simpler. I can just replace the valve and all the pipes.
Thanks for helping!

Yea, if you want to do a little upgrade of the bathroom now would be a good time to get a new faucet. You can install whatever fittings you will need into the faucet body before you mount it in the wall to make installation a bit easier.

Turns out that is exactly what and where it was. The pipe was very tight in the grommet and apparently one of the fins cut into the pipe. The hot water pipe was also tight in it's grommet but I saw no damage. Replaced it anyway.

A big thanks to everyone here that helped me worked the problem!
