Rated 5 out of 5 by from Very stylish The faucet is a great price for the quality you get. It is stylish and looks great in my kitchen. Very easy to install. It's a little smaller than my previous faucet which was the Windemere. I like Delta products because whenever I have had a problem customer service was always helpful and they stand behind their warranty.

Rated 5 out of 5 by from Great product I just love it. The water flows softly, I can now wash big pots and pans with room to spare.

Rated 2 out of 5 by from Looks good, handles feel like quality The hand held hose sprayer is weak. It’s a fan like spray and my older Delta was much better. It had a direct powerful spray. I found out after my purchase that I could have gotten delta free replacement washers and things replaced via you guarantee I am still thinking of replacing this new faucet & hand sprayer ..it’s frustrating by comparison! Yet, I have got to figure out how to determine the sprayer function direct vs fan spray before I blow more cash. 🫩😤🤷🏻‍♂️

Rated 2 out of 5 by from not enough pressure sucks must have restriction valve in it not good pressure
Date published: 2026-02-01
Rated 3 out of 5 by from Nice, but... Nice, but it lowered my water pressure. Also, you have to almost turn the faucets on full power before the water comes out and if you want warm water you almost have to turn both hot and cold on full speed. I like the material the hose is made of, but not enough pressure when using. I hope the sprayer holds up because my last faucet's sprayer I had to replace almost every month. It was a Moen.

Rated 1 out of 5 by from Poor craftsmanship We bought this product to replace our kitchen sink faucet, also a Delta, because the sprayer hose connector broke. We bought That faucet in January 2025. , from Lowes We bought a replacement hose there that was supposed to be a replacement for that specific faucet, we still had the box. The adapter for the end nearest the drain was too small. We had no choice but to go buy a brand new faucet kit. It was extremely frustrating
Date published: 2025-10-01
Rated 5 out of 5 by from Excellent Replacement Faucet Bought to replace an American-Standard kitchen faucet which was plagued with O-ring issues that finally gave out and sprayed water to the ceiling. We found this faucet at Home Depot and installation was a breeze. Because of the hard water in New Orleans, water spots were always present and eventually diminished the chrome finish. This DELTA looks great and and keeps a great looking appearance despite the hard tap water. I will however, coat the threaded hardware with a water-repelling grease to prevent the chlorine from seizing the threads. After all, one day the hot and cold valves will have to be replaced.

Installed 3 months ago. Within 2 days the sprayer began to drip when faucet is on and there sounds like air in the line, a thump every couple of seconds. If I use the sprayer the thumping goes away. Plumber was no help in fixing it. What could it be?

Asked by: Bkennedy
Hello! Thank you for contacting Delta Faucet Company! Reduced flow and loud squeaking sounds can be caused by debris, which can get caught in a few different areas of the faucet. Please shut water supplies off before starting this process. You will need a 1/8” Allen wrench if you have lever handles, a Philips screwdriver if you have knob handles, needle nose pliers, a quarter, a towel, and a bucket. 1. We will flush the diverter first; remove the spout, unthread the spout bonnet counterclockwise, and pull straight up to remove it. Inside you will see a black plastic piece that is the diverter. 2. Place your quarter in the slots on the diverter and take your needle nose pliers to twist it out counterclockwise. 3. Place the bucket behind the spout and around ONE of the handles. Turn both water supplies on. Please flush this out for about 30 seconds to a minute. To flush the valves: 4. Remove your handle with the 1/8" Allen wrench if you have a lever or remove the top cap to reveal the Philips screw if you have a knob handle. 5. Pull the handle off of the stem unit. 6. Remove the bonnet nut with your wrench. 7. Before removing the rest of the parts, verify the orientation of the stem. Lift straight up to pull the stem units out. 8. If you look into the valve, you should see a seat and spring. Pull these pieces out before we flush. 9. Place a towel around the back of your entire faucet, and place the bucket on top of the towel to catch excess water. 10. Have someone turn the cold water supply on for about 30 seconds to a minute. After this, shut the cold water off and move the bucket and towel to the hot side, flush that out as well. We appreciate your inquiry. Please reach out directly if you have further questions! Best Regards, Kyra Digital Communications Specialist
