No Put Old Tube Back With Old seal
Install New SS Braid
The last two Kohler one piece toilets I Installed had stainless steel flexes in the box with the toilet.
No wax ring though!
the last thing you want to do is solder next to a frozen pipe.
and i do regularly swap out hose bibbs and valves on threaded systems. of course cold water and areas where water will not damage anything
if you need a demo, joey and i will be glad to visit
Gave Her back her old Copper ...
She Then Asked me to Re-Install It I said NO ...
Then She Says It's Still leaking to look at it ...
I Looked , It's the Other Side ... Then I got accused of Replacing the Wrong Side LOL
I told Her I would Re-Do the Job and use Plated Lines With the Integral Ends ... At a discount ... (She is thinking about It)
