A foot pedal faucet is the biggest optimization I need to make. It's like giving yourself a third arm in many situations.

Kohler makes a touchless faucet. You wave your hand under the faucet and it turns on and off. I've had one for years, and it's great in the kitchen. Most commercial lavatories have the same technology.

I’ve got a friend with one of these. He has not been super happy with it. He mentioned installing the foot pedal next time instead.

I got it and absolutely love it. Takes a bit of getting used to of course, but after being in my kitchen I expect all taps to work like this.

The biggest downside is that visitors will be confused why the water doesn’t run (the physical tap is always left open but there is a “virtual” tap controlled by the sensor is not.

I so desperately want this, I think about it about 5 times a week and probably mention it to my wife as often. But in my old small house I doubt I could ever get one set up. Much better than a touch less one.

It's just a standard plumbing fitting, and it engages with the plumbing below your actual faucet. Space shouldn't be an issue?

I bought an one that attaches to the source line to the faucet, but I'm nervous to install it for risk of leaks.

Teflon tape is your friend when plumbing things together.

Not always. It only works with FIP/MIP connections. If it's a compression fitting you're just wasting money.

Compression fittings first question is "can you use a shark bite push fit instead?"

Second thing is, get a small amount of food safe grease and put it on the copper ferrule to make the connection: took me far too long to learn that.

Definitely. I'm more worried about the valve in the pedal being faulty and leaking.

Oh wow, I've never even heard of these. Now I want one, though my daughter is within months of being able to crawl, so maybe I'd better skip it for now.

I use a touch-sensitive faucet. Either way, this is a big upgrade given how often one uses a faucet.

Also vastly superior for sanitation. Commercial hand washing sinks use them for that reason.

Can't recommend a foot pedal faucet enough. They're not expensive!
