copper to flex kitchen sink.. please help

[imig93]

Thank you in advance for your reply I want to replace my old copper pipe flex line…. how will i do it? below is a picture

you could put some 1/2" sweat x 3/8" compression adapters on the copper after the ball valves. You could also turn off the water and remove the ball valves and put some compression angle stops on.

tha k you for your reply … will the compression adapters require saudering?

Why are you replacing them?

i figured it would be easier when installing a new sink as opposed to connecting the sink right where those copper pipes currently are(it may not line up right???and seems outdated )

Cut the copper pipe right below the reducing fittings. Make sure you get as close as possible so you have enough copper left
above those valves. Then put on 5/8" x 3/8" compression couplings and then you won't have to do any soldering. A lot of new
kitchen faucets have the supply lines already attached to the faucet. Then all you have to do is hook to the top of the compression
coupling.

5/8x3/8 compression coupling? it looks like 3/4 when i measured it(the lower copper piece) and i thought most sinks and stuff are 1/2 ? wouldnt that be a 3/4x1/2 coupling? or is that all wrong lol thanks for help

Are you saying the OD of the copper pipe coming out of the wall is 3/4"? Sure looks like 1/2", but again, pictures can be deceiving.

 

[TomFOhio]

If it doesn't measure 5/8 on the outside then I can't tell by the picture if its 3/4 or not.

gotcha…. so i cut it but its dripping from the ball valve it seems? should i just turn the main water off, remove ball valves and put a compression angle stop on? like someone else suggested?

i might have to do your second suggestion i cut the copper but it seems to be dripping a little from valve
