Great features.
I bought this for my kitchen, but it didn’t fit. I made an outdoor sink for my kids to wash their hands when they get done playing in the dirt and it works perfectly! It is stainless steel, and even come with a soap dispenser.

FANTASTIC
Delta is a well-known brand in the plumbing industry, and their showerheads and faucets are some of the most popular on the market. I recently had the opportunity to try out a few of their products, and I was impressed with the quality and performance. Now, let's talk about the performance. Delta's faucets deliver excellent water pressure and flow rate.

Looks amazing
I love this Delta- Knoxville single handle faucet. It is of great quality and value. The installation was very easy and I could do it all by myself. Looks gorgeous in my half bathroom. It goes well over a vessel sink. The installation instructions are clear and simple. It is well constructed and sturdy. I am hoping that this will last long.

Just going to install the Knoxville bathroom faucet, but besides the water lines to connect to my shut off valves there are two plastic or vinyl like tubes with an optional v connector. Never encountered this before. How should I use second lines?
Hello Valued Customer,
Thanks so much for contacting Delta Faucet Company!
The two supply lines on the KNOXVILLE™ Single Handle Bathroom Faucet MODEL#: 15854LF connect to the water supply. The quick connector tube fittings push into quick connector. Be sure to pull down moderately to ensure each connection has been made. Please refer to page 3 of the maintenance and installation guide for more details, I have attached the link below.
