Hello Thank you for commenting with your interest in our product. With the 766 faucet you need to hold the button for the spray function to indeed work. Hope this answered your question and you can proceed to check out.

That's too bad. Strikes me as a poor design as this doesn't allow you to do anything with two hands while the spray function is on (like wash produce, for instance). I will not be purchasing this product for that very reason but I appreciate you responding.

The faucet head it self stays on with out hold the button it is only if you wanna use the spray function you would click the black button on the head to activate this use. Both functions are to be used with out the hold of the button so you can have free motion of your hands. Sorry for the confusion.

So to clarify, you can simply click the button (without needing to continue holding it down) and the higher powered "spray" function will remain on?

I love the look but the function is not working for me. For one, I have to keep holding the spray function to get some water flow, secondly the flow of the water is minimal even holding it down. At this point I know there is something wrong with the head. Do you sell replacement heads.? This is driving me crazy and rather not replace ($$),
