This is the second Delta single lever kitchen faucet I have bought in as many years-for different homes. I like the ease of which the single lever and spout operate and is so handy for my 91 year old mother. The models I used both had the pre-installed water lines and a snap together unit for connecting the sprayer. Have been very pleased with both units. My only suggestion would be to make the faucet lever longer for ease of reach and control as was the case with the first one I bought two years ago. Very happy with the product and customer assistance. Will buy again if the need arises.
