Has anyone ever seen a kitchen sink faucet that can switch between 2 water sources? Kind of like the water guns that bars use to switch between soda/water, but for a household kitchen sink?

We are getting an under-sink Reverse Osmosis water filter soon, and looking at options to not drill a hole in our quartz countertop for the filtered water faucet. We still want hot/cold to work on the tap water, but also maybe have a second button to get water from the RO filter.

Anything like this exist? Thanks in advance!

Does your countertop have a soap dispenser now?

If so, just sacrifice that.

Otherwise, just drill the new hole.

Better than buying some freaky (and likely mega expensive) dual source faucet, IMHO.

No soap dispenser hole. Only the one hole for the regular sink faucet.

Looking for options other than drilling. So I'm looking for such faucet, if one exists, and if so I'll weigh the cost of buying a dual-source faucet versus hiring someone to drill a hole. My plumber will not drill, so I would have to hire someone to drill (and this is getting costly).

I was quite surprised that the only one that came up quickly in a search was only $30. ???

I would suggest you call the major manufacturers of kitchen faucets and ask them.

That would likely be your quickest way to find what's out there.

The $30.00 faucet looked the nicest of the faucets shown. The ones on amazon looked like commercial faucets. I
would be very skeptical about buying a faucet that only cost $30.00 in this day of age. You'll probably be replacing
it next year at this time. Just me thinking out loud.

My exact thoughts!

So, I just learned that the Reverse Osmosis system uses an "air gap" faucet, which the manufacturer said, means I need to use the provided faucet, not connect another faucet like the ones above. So it looks like I may be drilling that hole afterall.

Grohe has a setup for 2k to get carbonated filter water that’s chilled. Takes up the whole cabinet under sink but it works

Drilling that hole, particularly in "quartz" (which is a synthetic material) is no big deal. You could buy the diamond or carbide bit to do the drilling yourself if need be.

I have well water, and even after a chemical free iron filter, the water isn't drinkable in my opinion. So, I installed an RO system under the sink. Not only that, but I have a soap dispenser and an air switch for the disposal, so the installer drilled FOUR holes on site. No big deal. He did this in minutes.

You just need to ensure that the RO faucet is deep enough to penetrate the thickness of the countertop, and that you install it in a location not to interfere with anything else there, like the back of the sink.

There's very little pressure from an RO system, so a dual input faucet would make no sense anyway. The undersink RO systems have, generally, a 1 gallon pressure tank, The first 10-12 ounces come out readily, then it peters out to next to nothing as the pressure tank drains. If you think, for example, that you'll be filling the pasta pot to boil water from your RO system, an undersink unit won't work for you, you'll need a larger system. It's basically for drinking water, however I have a "Tee" in mine and I feed my refrigerator's icemaker, too.

The photo shows the work in progress last January. The wood frame is to hold the farmhouse sink. The hot and cold water is in, as is the drain in the right corner of the sink base. The disposal is there. The astute will note the hole in the upper right of the cabinet; that is for the loop for the dishwasher drain...

Now, in my car wash days, I had a 3000 gallon per hour RO system, with a massive multistage pump, membrane and filters that were the size of Sidewinder missles. No, you don't want that...

Good luck!
If you do get some estimates to drill that hole, I'm sure there would be some people on this forum that would be interested in the estimates.
Replying to you about estimates on hole drill, I'm having it done for $175 this week.

Drilling that hole, particularly in "quartz" (which is a synthetic material) is no big deal. You could buy the diamond or carbide bit to do the drilling yourself if need be.
While I know that's probably pricey especially since you pointed out drilling a hole in quartz is quite easy, I wanted an experienced pro to do it, for the piece of mind it will be done well. A local countertop store with great reviews will send their employee who does the cutting for the countertops they customize and install in homes.

The hole is not the expensive part, its the liability of possibly cracking the countertop that costs.
