General Faucet Installation Instructions


Rated 4.7 out of 5 by 9 reviewers.
Rated 5 out of 5 by Simple design great product This is a basic faucet, was easy to install, good water output, solid construction. Called Delta on an installation question and they provided great customer service. I would highly recommend this product to others. August 24, 2014
Rated 4 out of 5 by Delta kitchen faucet.... Generally have no complaints regarding the installation; quite straight forward. The plastic connection pipes are a question mark though regarding their longevity (even though they make things a lot easier under the sink). Faucet quality is OK I guess... but I wondered when the original Delta I pulled off the sink weighed almost twice as much as this new one. Makes one wonder exactly how much metal is used in faucets these days..... I hope these aren't like many cars.... flaccid after 5 years or so.... February 5, 2013
Rated 5 out of 5 by Like it! I have to custom fit the supply tubes because I had a larger fitting, but that was pretty easy. The faucet works great. It is lightweight and easy to use compared to the Moen it replaced. It has a lifetime warranty so I hope it lasts for many years. April 12, 2012
Rated 4 out of 5 by Great purchase! Very happy with customer service, product arrived in great condition-good quality product bought as a gift for replacement of existing faucet- easy to install. Would use Faucet Direct again. Excellent purchase for application - reasonably priced. February 2, 2014
Rated 5 out of 5 by Delta Kitchen Faucet Researched it on line and thought this was the best one for Arizona with its water saver feature. Contacted my plumber before buying and he said Delta was a good faucet to get. Replaced a 5 year old Price Fister that I was not happy with. December 24, 2010
Rated 5 out of 5 by Great improvement We replaced the faucet in our utility room sink. It was a great improvement. We chose the Delta stainless steel finish. Not only is it a high quality item, it really perked up the looks of the room. October 11, 2010
Rated 5 out of 5 by Great faucet for the price! Works better than a more expensive brand that leaked after one year. March 5, 2016
Rated 4 out of 5 by Rental property Installed easily. Seem to be really well made. June 26, 2010
