For when you move just replace the grey line (now with the tee) with another continuous piece.

If you don't mind going without water for a bit just turn off the valve, take out the grey line (between the valve and the faucet), grab a piece of the water line for your ro unit, go to HD depot the show them what your planning. Since the grey line is probably bigger than the one for the ro, you'll need a tee and reducer.

Might be a really stupid question but what kind of fittings am I looking for? All I found at my HD is brass. Didn't seem like the right stuff.

They also did not have anything small enough to use as a valve for the RO line (1/4" OD)...the smallest they had was again brass and 3/8".

Ughh...this is getting frustrating.

Any reason I can't just use the vampire teeth? Are they meant for actual pipes? Im guessing not meant for tubing?

For the drain I got the 1-1/2" "Y" fitting and a reducer that gets me from 1-1/2" down to 1/2" but again thats as small as I can go with fittings from my HD. They had nothing to go any smaller. I think I may have a 1/2" to 3/8" on an old Ozone Reactor I built but that doesn't do much since the waste water line on the RO unit is 1/4" OD.

Jeez...I though this would be a snap. The only reason I am in any hurry is that I have no more RO water in my top off and I am watching the sump water go down more and more by the hour

Gonna have to use dechloronized tap water tonight I guess.

Might go back again tonight to figure this out...if brass is ok to use?

Sure, brass should be fine, looks like that's what is on your red RO/DI line saddle clamp anyway. You might ask about nylon compression fittings too. They may be in a different aisle but shouldn't be too far from the other plumbing stuff. The only other thing that comes to mind is 'john guest' fittings?

If you have the clearance at the cold water shut off, you're best bet may be to go with the 'vampire' saddle clamp fitting. You'll still want a shut off valve for the RO/DI though. No getting around that.

I would like to try to do this without the vampire thing I think...

When I was in HD I did find all the stuff I would need to get the intake side of the RO unit working (Would look kind of frankensteined together with all the reducers and such) but I couldn't find a way to work out the drain side.

I guess I could use all kinds of reducers and make it work but it just seems like such a mess to do it that way.

They do have a VERY limited amount of John Guest fittings but nothing small enough.

I think unless I go to another HD I will have to use brass. I am fine with that but just wanted to make sure it was safe to use.

And yes of course, the fittings on the unit are brass

Ok, well I am going to go ahead and make the trek to a different HD and find the right stuff. It just seems so dumb to live across the street from HD and have to go to a different one 30 mins. away

But the HD across from me is a joke....they call it a "new kind of depot" and do not carry much building supplies (not even 2x4's!!!). If you need tiles or tropical plants though, you have quite the selection. It should be called "Home Depot Lite"...

here's a link (with picture) to that saddle tee for your drain.

Nothing wrong with brass, it's all fresh water.

If your going with the extra valve just get one for after the tee and reducer for the 1/4" line (like the on in the picture with blue handle).

You unit didn't come with a saddle tee for the drain (looks a lot like the piercing valve but bigger and no valve)?
