what does it mean that it is a "non air-gap" faucet?
1600622
Basically, imagine if your drainage tube were placed in choclate shake? It is feasible some of the shake material could be sucked up into your Reserse Osmosis syatem. So hen installing the drainage tube? Just follow the directions as to proper placement. By doing that, you will not not suck contaminant(shake) in the reverse direction. Non air gap means... if a vacum is formed it will suck back fluid. An air gap faucet, when a vacum starts? Will release the faucet from the suck mode. Air gap faucets are used on submarines. I imagine you are not instaling it there? Just follow the instructions.

Mr. Fox's answer regarding the back flow prevention is correct. This faucet requires constant pressure on the supply line at all times. As installations do vary, you may want to check with a qualified plumber for your particular installation or planned installation.

It has no back flow prevention that stops water in the drain from being sucked into the RO system. Depending on your installation, an air gap is sometimes recommended.

It moves forward AND backward. The measurements are as the previous message states.. I love the looks but found out when it was installed that it is a "low flow" faucet. Guess we missed that description. I do miss the full force flow tho'.

Sorry to hear that. Maybe your counter is higher than typical 32" bathroom counter or wall valves lower. Plumber are notorious for put things where ever they feel like it. The only standard they seem to all do is waste line for WC at 12" off the wall.Re: the faucet. It works well and looks good.

Yes you can use this faucet for air gap. I am sure you have proper RO drain connections. This piece comes complete with 3 tubes. The piece you will get will not look as shown in the picture. It is not of solid construction as shown in picture. My piece was leaking from the vent hole and I have to throw it.

We installed it without the bottom flat piece. It is not a part of the actual faucet.

It's rather flat. The water does not build up in the sink when running unless the stopper is in. FYI I love this sink and have bought it on 2 occasions. Much more useful than a double sink.

The faucet is non air gap. a supply line only,no drain line for a reverse osmosis system.

I think it means the hose connections for the fixture are threaded, not the end of the spout

If it utilizes an air gap faucet there should be no issues. However, I can only speak with experience about my system. WIC, not Nelsen.

I looked up my original order from last year: it says 'one hole faucet with additional knockouts' -- I used a one hole faucet so my handyman didn't need to do any additional reconfiguration... the knockouts may be more apparent on the underside of the sink?!?!? suggestion: call amazon and ask them for # of Pegasus company and call... if they want the sale, they should be VERY helpful... happy holidays -- hope you get the answer you need!!! :) angela

The flange at the bottom is OPTIONAL, primarily for someone that is converting from a 3 hole faucet set to one. I installed mine without it as I previously had a one hole faucet. It looks beautiful without it.

My understanding is that air gap accessory is designed for dispensing water from a Reverse Osmosis system or a Water Filtration system that requires a drain connection with an Air-Gap. Mine did not.

I believe it refers to being attached directly to the counter, versus the wall, etc. I had holes drilled into my counters on either side of the faucet, and what you see in the picture is exactly what is visible above the counter surface.

I'm sorry I don't know what that means for sure! We have quartz counter tops which sit on top of the stainless steel sink and this sits on that just fine. We don't have a lot of room between our bar height counter and the faucets but this is narrow and doesn't take much room. We've only been in our house a month and even though the ends do move easily, I have not knocked mine off once.

The water lines under the counter top are flexible between the handles and faucet. Hope this helps.

The valve they are referring to is the side mounted hi flow valve. (The one that says "Filter", "recirculate", "backwash"...etc). There are other models where there are no holes on the side and as such the plumbing and multi position high flow valve goes on the top....This is NOT that type of filter. So this ad means you get the pressure gage and air bleeder valve on top and not the side mounted multi position valve for "Filter", "recirculate", "backwash"...etc

Hi, This is a vessel faucet. most of the customer mount it on top of the counter top. If you mount it on the sink, it will too tall and water will splash.
