It seems that that they still sell the faucet at Lowes, Item # 756559 Model # 67157-1027H2, on line but they do not have the replacement hose, and I could not find a website for the company. I went to Lowes and found a faucet that looked exactly the same with the same type of sprayer connection, but now sold under the Delta brand. So I called the 800 number for Delta and asked if I could buy just a sprayer hose and sprayer (The way this sprayer is connected you cannot take the sprayer base off the hose, you can only take the head off). She said no, but they do have a lifetime warranty on their products, did I know the model number? Slight ethical dilemma here. But I had offered to buy one first. So I gave the model number of the identical Delta faucet, and four days later, a new sprayer and hose arrived in the mail, ready to install. Now, I was so happy to get a new sprayer and hose, and impressed with the ease of using the Delta lifetime warranty, that I did go out and buy a new Delta faucet for another sink. Before you think, well it must be a poorly made product if the sprayer hose leaked, I will say the faucet otherwise works perfectly and is over ten years old! Thanks for your help Terry. This is such a great site for us amateur plumbers.
