I am trying to install my daughters LG refrig ice maker. The problem is that all her pipes through out the whole house are galvanized. The installation kit that I purchased only peirces through copper tubing. Is it possible that I could purches an adapter that I could instal to the faucet that connects to the cold side of her washing machine. Or what are all my options.

Thanking ahead for your advise.

Assuming the ice maker uses 1/4" tubing then these fittings will work for you:

Brass hose fittings - PlumbingSupply.com

This is a female hose fitting to compression adapter.

3/4" FHT x 1/4" compression(swivel) with hose washer

This is a Hose "Y" adapter with dual shutoffs.

3/4" Zinc Dual shut-off hose fitting

Make sure you use one of these inserts in the tubing. Pick the corrct size. There should be one in the kit.

Tube Insert for Nylon or Soft Plastic Tubing on Hy-Lok USA

Use a plastic ferrule rather than the brass one supplied in the hose to 1/4" adapter if the supply line is plastic. It should already be in the kit.

Connecting An Icemaker

KISS gave you good run down of you options... It is a common question that we have to deal with on every day bases. Big Box Stores are well stocked to sell you just about any connection you need for icemaker installation.

I would not suggest to pierce galv. Pipe. You can always get a double angle stop and run your 1/4" line through cabinets all the way to the fridge. Leave 4' of tube extra, coiled behind the fridge. This way you can easily pull the fridge in and out.

Additional Info: We stopped using 1/4" copper for icemaker installations some time ago for simple reason: They leak. Once you connect it to the fridge you have little control over the line as you are pushing fridge back against the wall. We use high density plastic tubes or even better, 1/4" s.s. braided lines. These work best. They come in various lengths up to 10'. If still too short, we use 1/4"x 1/4" brass compression coupling to add another length.

Ya beat me to the punch milo,
A three way FIP angle stop is the answer. With the threaded end 1/2" and the outlets 3/8" (to sink) and 1/4" (to ice maker). Don't forget to Teflon Tape the thread on the stubout.
Good luck. Tom
