Delta Classic Chrome 4-in centerset 1-handle WaterSense Mid-arc Bathroom Sink Faucet with Drain

I'll use the example it does have great features

I bought it because I like Delta and reviewing things in the store this one had good features I liked, single control that could be a lever or knob, selection to limit the hot water temp, and large, plastic, mounting posts that won't corrode. Installed myself with no problems!

Great faucet

I've had only Delta faucets in my house for years. I got this faucet to replace one installed in 1974 and couldn't be opened to replace the parts. I liked the new one when I saw it and bought that one with the water lines, new drain, etc. it had everything needed but the tools. Once the old faucet was removed the installation of the new one was easy. It works great. And with the new diamond seals it should last longer then me.

Love the look of shiny chrome!

I bought this a week ago and so glad I did!

Nice, sturdy, solid function

Nice, good looking, fairly easy to install and solid function. The pex lines are quite long, somewhat difficult to route but seem to work well. Would definitely recommend. Good for kids/spare bathroom.

Easy installation

Selected this model for its practical style and its 3 function removal sprayer. Operation of each spray function was not lacking in anyway and easily met my expectations. Very happy with results. Did feel the need to go on line for installation instructions specific for this model since instructions provided covered several models making them somewhat difficult to follow. This 78 year old is very happy with the ease of installation after removing our garbage disposal for needed access, removin...

good looking products, long lasting

I have used Delta products before and have always been happy with them.

Early problem

I bought and installed a #521-DST-A in late 2014. From the outset my wife could not turn it completely off. If she centered up the flow handle, there was a running leak. I wsa more patient in learning how to get a no-leak position for the flow control handle: it was a little beyond the centered position. I have had to somewhat carefully find this position for the last five-plus years. She has been taught to do the same, but complainingly. Recently we have had regular and random visitors who...

Leaks

Here we go again. Just got the leaking kitchen faucet fixed and the bathroom starts dripping. Fits since they were installed at the same time 2 years ago. Delta sent me a new cartridge for the kitchen unit which was not a major problem to replace but one needs the right tools. This is not what I want to be doing every two years.

Cannot install water fittings.

Instructions do not match faucet model. Cannot install. Water connections do not insert into outlet fittings, because plastic sleeves are fixed to very end of tubes.
