What are the two different check valves that come with the faucet?

Contacted Grohe for this. The yellow-on-yellow (white for other handsprayers) is rated for 2.2 gallons per minute. The yellow and green one (same for other handsprayers) is rated for 1.5 gallons per minute. The water pressure is pretty much the same with either one, and the lower flow check valve does NOT affect the sprayer function.

The check valve with the green on one end is for water conservation and the yellow is for regular water flow. The "teepee" one goes into the faucet head.

I called Grohe directly with this question, and was told one is for low flow.

its the same one that came with the faucet ..unfortunately its plastic and if you have hard water it will wear out faster i think

The difference is the air gap. If replacing an existing faucet, check the number of hoses you have. Two means there is no air gap, three means there is. Additionally the air gap hose (usually black in color) would be attached to your sink drain and acts an anti siphoning system.

I am not sure what you mean by valve, It does not come with supply line valves, but I replaced mine with new 1/4 turn shutoff valves when I installed the faucet. The faucet works great!

The valve that you need is sold by Grundfos. You can buy as many separate valves as you need.

Any standard faucet. you just screw the other one out, and screw this one in. It screws into the inside of the faucet end not over the outside of the faucet.

Faucet set is complete with valve. Tub and Shower sets do not come with the valve(s)

In my research, the K-304 valve is not included. Check on Faucets Direct website for all specification requirements for Kohler Devonshire products.

Mine came with a couple of different adapters.. I can't say for sure which, if any, of them would accommodate your faucet. I will say that you can get any size adapter you may need from any big box hardware store for very little cost (prob under a dollar). I love mine. Good construction, works great.

Brass. Very good quality, smooth operation. The spigot may another metal but the valves are brass.

Typically your house pluming has a valve in the wall for hot and a seperate for cold and each twist on/off and have a male thread outlet. These valves are typically standard (same at any house) and are not included. The faucet has it's own valve built in (kind of what makes it a faucet) that combines the hot/cold and on/off depending on where you position the faucet lever.

The faucet as packaged when I purchased it came both with the rough-in valve and finish trim.

You can either get the one that comes with it or use another. The one that comes with this faucet matches and is very nice and extremely well built. I have had this for almost a years and it is fantastic. The faucet is very large and goes perfect with the Farmhouse sink that I purchased. If you want something inconspicuous, this is not it.
