use cold water line for sink and icemaker?


I'm in a condo and the water supply line is behind a 3 firewall so it's a pain to connect with. The cold water supply is already coming through the firewall to provide for the sink and there is an existing shut off valve. So if I could install a T after the shut off valve, the supply line would feed both the sink and the ice maker and the one shut off valve would shut off water to both the sink and the ice maker. The icemaker calls for a pressure between 30 and 120 PSI. Any thoughts on the feasibility of this approach will be much appreciated?

How far away is the ice maker and the sink.
They make a double shut off so you could run a line to the sink so there would always be full pressure and the other line could be run to the ice maker.
One other benefit would be that if one needed shut off the other fixture could still be used.

The shut off will actually punch a hole in the pipe

That's a saddle valve, I'd never suggest someone use one. The reason being is they tend to plug up or leak. A double sut off would have full flow and not plug up.

Do not use the saddle valve.

There is not enough pipe exposed on the sink side of the firewall. It would have to be sealed in behind the firewall.

Horizontally - just 3 feet. A double shut off sounds like an ideal answer. Is there a cheap tool I can use to measure the pressure...or am I worrying about a phantom problem? Our water pressure in the building is excellent. I'm on the 12th story of 24 stories.

Install a 3/8" compression tee above the existing stop (shut off valve) using a 2" length of soft copper tubing. Connect the faucet supply line to the tee, connect the ice maker to the tee. Use copper tubing to connect the ice maker.

Yes.
Another option.
It will allow you to shut water off to one without affecting the other.
