Rated 3 out of 5 by from Basic faucet There is a pressure issue when you turn it on hot or cold. Never experienced that before this is my first purchase of a Delta faucet.
Date published: 2026-03-01
Rated 2 out of 5 by from Totally disappointed. Delta must have discontinued their quality control system. This faucet was easy to install with one exception: the spray unit is not threaded enough to tighten on my SS sink. Now I have a sloppy and wiggly base for the sprayer. The handle of the unit is crooked and tilts to one side. The red and blue plug that shows where hot and cold are is now almost completely red. The blue has worn off and I only use water and a soft sponge to clean the faucet. I can't express how disappointed I am with this Delta faucet. As a retired building contractor, I have installed dozens of faucets in my career and have never seen such sloppy workmanship.

Rated 4 out of 5 by from Easy installation but Easy installation but after the install I turn the faucet on and it pops hot or cold. My other faucets never did that. I’m not adding a bladder above my tank.

How do i fix leak, cartridge or seats and springs

Asked by: Tom m
Hi Tom m, Thanks so much for contacting Delta Faucet Company! It is possible that a flush could resolve this issue with the FOUNDATIONS® Single Handle Kitchen Faucet With Spray MODEL#: B4410LF. To flush the system, turn off the water supplies. Remove the aerator and turn faucet handle all the way on. Turn on the hot and cold water supplies and flush water lines for one minute. This flushes away any debris that could cause damage to internal parts. Check all connections for leaks. Replace the aerator. Re-tighten if necessary, but do not overtighten.

THE DOCUMENTATION WITH b4410lf-SS states "Although its finish is extremely durable it can be damaged by harsh abrasives or polish. simply wipe gently with a damp cloth and blot dry" Are you kidding me.? Just wiping leaves discoloration

Asked by: Sheeba
Hi Sheeba, Thanks so much for contacting Delta Faucet Company about your B4410LF! I am sorry for the inconvenience you are having with your finish, here are a few recommendations. Always blot dry any water from the faucet surface. Allowing water to evaporate on the surface can lead to a build-up of mineral deposits. Cleaning with a damp non-abrasive sponge and buffing it dry with a clean soft cloth should help keep your product looking beautiful. To remove water spots, use warm water and a soft, damp cloth. Hard water stains may be removed using a 50/50 solution of white vinegar and water. Make certain that you rinse the surface thoroughly with water afterward. Please contact us directly if you are still having issues with your finish. Best Regards, Nicole Digital Communications Specialist
