Compression fittings part 2
I posted some other questions about compression fittings in another thread.
still having issues with slow leaks under the kitchen sink.
I wound up cutting off the sweated on valve to get rid of old work. Got a brass craft mult turn valve with 2 outlets so I have less joints.
Put this new valve on the pipe. Tightened the compression fitting - the box says 1/2 turn after nut begins to take hold or 'bite'. Is that mean 1/2 past hand tight?
I still have a slow leak after 1/2 turn past hand tight.
If I undo the connection to check that the pipe / everything is clean, can I reuse all the parts? or the ferrule / something else needs to be replaced.?
Thanks

Then tighten 1/2 turn.
If you over tighten, it needs redone with a new ferrule. Over tightening could also damage the pipe, the pipe must not have any depressions.
You will know it's too tight if you can't easily put another 1/4 turn on the nut.

Make sure you clean the pipe just as you would if you were going to sweat it, before you slide on the nut and ferrule.
I always put a smear of rectorseal on the pipe before sliding on the ferrule, and a smear of it on the ferrule. It lubricates the nut and allows it to deform the ferrule easily to form a tight seal with the pipe and fitting. Since I've been doing that, I've never had problems with compression fittings leaking.
