I am remodeling our kitchen and have come up with a dilema on the sink. We want to use a stainless sink and a single handle faucet with spray hose. My wife wants a ‘built-in soap dispenser. I am told that local codes call for an air vent between the dishwasher and disposer. So, with 3 holes for the faucet, another for the air vent, and another for the dispenser I am up to five, one more than normally available. I am reluctant to try to drill an oversized hole in a SST dack. This poses some questions:
1) If codes call for an air vent, must it be mounted above deck? I once had a plumber put one below the deck (inside the cabinet) but that was in another state with much laxer code enforcement.
2) Does anyone know of a single handle faucet with a spray hose where the faucet mounts in a single hole? I saw one today but the hose nested in the faucet mount flange which covered 3 holes. I could leave of fthe mounting flange (a separate component) but the spray hose would have no place to seat when not in use.
I do not like the faucets with removable sprayer – they never seem to seat properly when not in use
Thanx, john

single hole for faucet
single for sprayer

air gap.
4hole, or three with the hose in the spout.
I believe there are some 5 hole sinks, check elkay.

My own DSH/W has its own vent , actually even to the outside of the house (3/4 hole thru the wall with a 90 deg elbow pointing down). That usually complies with the strictest codes, no sink involvement.
See it is your 2nd post, welcome if no one has already said so.
BTW, esp. for code related questions, it helps to fill in your profile (double click on your own name on the post) and likely someone knowledgeable from your area will respond.
junkhound, did I miss something on the thread? I thought we were talking about an air-gap now we are talking about a vent, what did I miss?
Shacko, my very loose use of terms here is your problem. But you have to admit that the "air gap", if that is what they want to call it, serves teh same purpose as any vent. It is there to prevent a siphon. Same difference. I called it a thingy. So vent, thingy, do-hickous, or air gap.
They are not the same things, a vent's purpose is to protect the trap seals so that they are not sucked dry by the discharge of a near drain, a air gap is used to break negative pressure so that the appliance [i.e. dishwasher] dosen't back-siphon waste water. FYI on a potable water system a vacuum will suck past a closed valve. Bottom line, they both prevent a siphon. "May the force be with you'.
Shacko:
"Bottom line, they both prevent a siphon"
Are you now quoting me?
Just agreeing with the basic statement.
Gerber 40-400 comes with a removable deck plate so you can mount it three-hole or single hole. The ceramic cartridge has a lifetime guarantee.http://www.gerberonline.com/catalog.aspx?categoryID=1346&itemID=2889More info & install instructions http://www.gerberonline.com/fileLib/0008060C.pdf
Sorry for the confusing terminology, it is a vacuum break per the plumbing code here. <G> Basically just a standpipe with Dsh/W dumping into the top, the air gap (which in my case is vented outside vs out the sink top) prevents any (somehow generated) low pressure in the dishw. from pulling dirty water back in .
In my previous house I had a single handle kitchen faucet that mounted in one hole. The faucet head pulled out and served as a spray hose. I don't remember the brand, but I bought it at a local Ace Hardware store. There were several on display if I remember correctly.
What Junkhound is reffering to is a "Johnson Tee"
Might not be applicable if your just puting in a new sink.
since a "johnson tee" is in the wall.
Here is a quality single hole pullout.

Hole saw. That's what I used on my own sink. Put the dispenser where I wanted it, not where there were predrilled holes.

Ok, I personnally know at least a half dozen people who have done the following.
Forget teh soap dispenser for a moment.
Install the vent or just set it in place and hope the inspector does not look too closely.
Inspector leaves, throw the vent away, install your soap dispenser.
Mankind lived for millenia with out vented dishwashers or what every the vent-thingy is supposted to be for.
That vent thingy is actually an air gap, and it serves no function for the dishwasher. It is there to keep the dw from siphoning the sink drain trap.
Don't think I have ever heard of a trap being sucked dry by a dishwasher operation, but it is most codes for some reason, so.....
Our local inspector does not require the air gap to be mounted on the sink. It can be on the counter top, but it is your mess to clean up when the darn thing stops up :)

"That vent thingy is actually an air gap, and it serves no function for the dishwasher. It is there to keep the dw from siphoning the sink drain trap."
Yeah, what I said. LOL!
Sure anything can happen. This is a pretty recent code requirement and only in some areas. A guy has to ask himself . . . Self, do you ever remember anyone having a problem with their dishwasher sucking dirty water in from the sink or sink trap when you were a kid? Self, how many dishwashers do you think were in operation prior to the new code? Tens of millions perhaps?
Sure anything can happen. And we can make millions of code requirements to address them all. But, should we?
And I know you did not come out on either side of this issue, so don't confuse my fun with this issue as being flip with you.
To each their own. This one seems low on many people's lists.
I have taken nearly as many out as I have installed over the years.
Most air gaps I have installed with dishwashers have a 3/4" line from the dw to the air gap, and a 5/8" line from the ag to the drain/trap or disposal. The 5/8" line gets stopped up with gunk if the HO isn't annal about scraping the dishes clean before putting them in the dw.
You can't change the HO habits no matter how much you preach. I just rework the discharge line without the ag , but leave it in place to fill the hole. You have to be sure to keep a high loop in the line and run it all in 3/4". Most of the time that solves the blow out of discharge water at the air gap because of a stopped up line.
Dave
"...be sure to keep a high loop in the line..."
Dave, leaving a high loop as you suggest - secured in place - is what I do instead of installing an air gap device. Never had a call-back because of back-syphoning the kitchen sink trap dry.
Edit: P.S. I am not a plumber.

Check this out. http://tinyurl.com/dbv7d I never used this faucet, so I don't know if it's any good, but it's cheap. There are lots of single hole faucets out there, in many price ranges.
