Plumbing help for garage sink

[David Paul]

So I am replacing an old plastic slop sink in the garage with a SS used commercial sink from FB Market place. The old sink just had 2 facets for the hot/cold water that hung over the old sink. They are soldered it place on the other side of the wall which is in the basement. They are behind a drain pipe that was put in after the facets were installed, making it impossible to get at. Of course there are no shut off valves to the faucets.
Plumbing is not my forte. The “new” sink has threaded adapters already soldered on to the 1/2 inch copper pipe for the built in faucet. My plan is to cut the 1/2 inch copper supply lines in the basement in an area that is accessible, and attach compression fit shut off valves, 1/4 turn. I’m guessing I can get the shut off valves with a threaded end. I would then attach a flexible SS hose between the valve and sink, about 3 feet.
Does this seem like a doable plan? Any other suggestion? TIA….

Without pictures I can’t intelligently discuss plumbing.
With enough time and money almost any thing can be accomplished.

Hard to say exactly without actually seeing it but your plan sounds solid enough. Just attach a set of long supply lines to the sink and run the other ends (where they're easily accessible enough) to shutoff valves. You got this dude.

your plan will work. assuming I am understanding your post correctly.
I would probably remove whatever is on the new faucet and just get flexible supply lines to connect to the faucet .
for the lines you probably the shut off end @ 3/8 compression and the faucet end @ 1/2 IP . without pictures tho, it's somewhat of a guess

Thanks guys for the feedback. Pictures for reference :

First picture, new to me sink.
Second is the faucets that just hung over old sink, frost proof but the garage is now heated.
Third is the new sinks water connections.
Fourth is where the current faucets enter the basement.
Last picture is where I could place the new shut off valves.

Thanks again for your time.

Did the old sink just sit in a cabinet under those two wall faucets? Where did the old sink drain?

The fittings on the back of the new sink are drop-ear elbows with a short section of copper pipe soldered on. It's a standard connection method, but usually the ugly part is inside a wall where it doesn't matter.

I would cut the supply lines in the basement in a convenient location, and install 1/2", quarter turn ball valves in the line. You can get them in the Sharkbite version and they are very quick to install. Just make sure you mark the old pipes (to measure how far they go into the Sharkbite) and clean them up well with sandpaper, so you make sure the shark-bite goes on far enough and makes a good seal. After that your house water can be turned back on and you can take your time figuring out the routing of the new supply lines to the sink. If you install your shutoffs inside the heated house, in the winter you can turn the water supply off inside and open the sink faucets if freezing is likely.

Without knowing exactly how and where you plan to mount the sink, it's hard to know how you might set it up. Copper lines are often used, but PEX can also be snaked through, and usually will not require soldering skills. PEX also gives you some additional protection against freezing, since it can expand and contract a little, while copper lines might split open.

Sounds good. For the stops get something with 3/8” comp outlet. On the 1/2” male adapters (new sink), screw on 1/2” FIPx3/8”comp adapters then make the tie in with a flex hose with 3/8” comp on both ends

This should help answer some questions. The new sink will just slide in to replace the old. The black piece is made up of 3 2X’s to space out the facets. That is being removed so the new sink will sit flush with the wall. The drain will just need a little reworking. Thanks for the tips on the shark-bits and the right adapters.

 

[David Paul]

Done. Thanks guys for all the suggestions. Used the shark-bits, made the job much easier.
