How do I hook up an RODI to a sink?

[Ocean’s Piece]

So I know nothing about plumbing or parts whatsoever and I want to be able to hook up my rodi under my sink instead of connecting it to my hose outside. I would connect it to my faucet, but the adapter that it came with doesn’t fit. I have two options (or at least I think): either connect it to the faucet with some kind of adapter I would need to buy or hook it up under the sink. Here’s what under my faucet looks like:

It’s blurry I know. It’s the best I could get though

Here’s under the sink:

I need the adapter to connect to 5/8” tubing. Please tell me if I need to provide any more details

I’ll say that hooking it up to your faucet is the easiest way. (“Best” way is subject to opinion— LOL.) Lowe’s/Home Depot/BRS should have what you need.

Whichever route you go, make sure NOT to use hot water!! Best wishes

Thanks I’ll check it out. I just don’t know if those adapters will fit my sink

Believe it or not, some faucets are so cheap at Lowe’s it might actually be worth it to buy a new faucet that fits the adapters you have on hand. It just all depends. Best wishes with whichever route you take.

I’ll tell you how I did mine it may help…I put a “Y” connector on the water inlet for the washing machine, then fitted a ball value to that, stuck a piece of rodi tubing into that, all I have to do is stick the tubing into the rodi unit when needed and turn the ball value.

all I needed to buy was the Y connection, an adapter of the same size of the Y connector that comes with the correct size hole for the rodi tubing and the ball valve, I already had a long piece of rodi tubing to stick in the unit when using it.

My apologies if you've already tried this and it comes across as me telling you to do something you've already done...

But in your pictures of the faucet, it looks like the aerator is still installed (the little disc with a bunch of holes in it). Typically that piece actually just screws in and out of your faucet. Have you tried removing the aerator and seeing if your adapter fits after you've removed it?

I have tried but it’s near impossible. I may give it a whirl again. It’s stuck on pretty good

You might need to use a pair of pliers to get it off then. It's supposed to just be hand-tightened, but if it was screwed down with a tool, or if it's been screwed down long enough that corrosion has set in around the threads, then it might be impossible, in which case no faucet adapter will work and either replacing the faucet or tying in to the plumbing under your sink would be your only options.

Fortunately, the plumbing under the sink is not terribly difficult to use, and the fact that you have flex tubing under there might actually make it easier for you. Is the under-sink tubing the 5/8" tubing that you need to connect to, or does your RO/DI unit use 5/8"?

It’s the rodi tubing that is that size. About to give the pliers another shot

Try some WD 40 and channel locks to remove

Hold the faucet tight with a rubber pot holder while you use the wrench.

To no avail. I guess I’ll just keep doing it outside. Or if I want to try again I’ll resurrect this thread if I get some dire need to use the faucet. Thanks guys

Also, what RO/DI unit are you trying to connect? I feel like we probably should have asked that earlier. =)

Basically, if the faucet doesn't end up working out, then you'll need to splice some connections into the tubing under your sink. This is a fairly easy procedure, you just need to know which fittings you need to look for.

You may have already figured this out, if not this may help.

Go pick up one of these keys at your local Lowe's or Home Depot, make sure it's the right size for the aerator underneath the sink. That should help you unscrew the aerator and then allow you to hook up the adapter.

In my case, even after removing the aerator, the adapter caused too much back pressure on the cold water line cause it to feed back down and leak underneath the sink - so just make sure you test it out!

Good luck, hope this helps. Tough to find this info out there sometimes, I'm with you.

thanks so much for this. Still haven't found a solution for this so I'll definitely be checking this out.

I personally would just use a tee/valve similar to this one that goes onto the cold water line coming through through wall. It makes for a nicer looking install than having the aerator with a ball valve on it IMO.
