New faucet - how many holes?

pb927September 9, 2013


I'm installing new granite countertop and have purchased a faucet to go with it (Hansgrohe Talis C).

The faucet I purchased only needs one hole. I know some people like putting in a second hole for a soap dispenser, but we really don't need one. Is there value in getting the second hole put in anyway? Anything wrong with just installing a faucet with one hole?

No, no problem. If you need a second or third hole in the future, you can have one drilled on site - messy, but doable.

Have you considered an air switch for your disposal? That is on my top 3 best new things in our new kitchen. That would be one more hole. Also, does your area require an air gap for the dishwasher? Hopefully not, but if so you'll need one to pass inspection, and therefore a hole for it.

Thanks, I appreciate your response!

What is an air switch? We have a disposal, but a standard on/off switch. We're planning on keeping the same disposal.

I don't know what an air gap is either. Our current sink doesn't have one - I assume that means the new one won't need one (right?).

Air switch - best thing ever!! It's a push button near your faucet that switches the disposal off and on instead of the switch on the wall. Here's mine:

What you buy:

The button is what you see on top and it comes in finishes to match your sink. The box plugs into your outlet under the sink and the tubing connects the box to the switch and the box to the disposal. The whole thing costs around $52 and is a cinch to install. No more drippy hands getting everything between the sink and the wall switch wet. They're available at Lowe's, Home Depot, etc. as well as on line.

Air gaps - if you don't have one now, you don't need one. It's an antiquated way of making sure that the water from your DW doesn't back up into the clean water supply. Modern DWs have "high loop" plumbing that serves the same purpose; however, a few states still require the air gap.
