how do i stop leaky supply lines under the kitchen sink?

Question

i replaced our kitchen faucet and since, where the supply line connects with the copper piping, water beads up and drips. do i want to use some type of plumber putty or replace the supply line? or something else?

Answer 1

if you use flexible hoses then any misalignment will not put the joint under strain. (In the hardware store there are steel-braided flexible hoses especially for this job) This is a solution for an amateur, like me!

Answer 2

Make sure there is a washer in the supply line connection and then wrap teflon tape clockwise over the threads of that connection to get a snug fit.
It most likely is an incorrect seating (not set in alignment) of the new connection to the water supply line.
Just remeber to turn the water supply line off before starting this project. Good Luck!

Answer 3

The problem could be that the threads are ruined, cross threaded, or maybe a fitting is cracked.. If that is the case
(I don't think that this is your problem because from what I read in your question, both connections are leaking, probably due to a incomplete seal) than they'll have to be replaced.
If that isn't the problem than try unscrewing the connections, put some teflon tape on the "male" threads and then tighten (don't use overkill) until they don't leak.

Answer 4

just to verify the kamikaze kids answer is about the best and first solution you should try,because if it is fairly new like you said you may have forgot the washer or did not snug it up enough.
