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.

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.

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.

Q&A
put in delta faucet # B4410LF to replace old shabby one that still ok . Now when I turn this one on after it sets 1/2 hour or so I get a one time clunk from the body .Not the first time I have changed a faucet why is this happening and how do I fix it .
Hello Help TLP,
Thank you for contacting Delta Faucet Company! I am sorry this information was not readily available, and I am happy to help you!
The clunk you are experiencing with our Delta Faucet FOUNDATIONS® Single Handle Kitchen Faucet With Spray MODEL#: B4410LF is caused by debris in the faucet or diverter, We do recommend flushing the valve. Here are the steps for flushing your faucet.
Please shut water supplies off before starting this process. You will need 1/8” allen wrench if you have lever handles, a Philips screwdriver if you have knob handles, needle nose pliers, a quarter, towel, and bucket.
1. We are going to flush the diverter first; to do this we will need to remove the spout. Please unthread the spout bonnet counterclockwise and pull the spout straight up to remove. Inside you will see a black plastic piece. This is your diverter.
2. Please 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. Please turn both water supplies on. Please flush this out for about 30 seconds to a minute.
4. Please remove your handle with the 1/8" allen wrench.
5. Please pull the handle off of the stem.
6. You will now see a bonnet nut, please remove it with your wrench.
7. Remove the cam and packing, then please pull the ball assembly out.
8. If you look into the valve, you should see a seat and spring. Please pull these pieces out before we flush.
9. Please place the towel behind the back of the faucet then put the bucket over the top of the towel.
10. Please 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.
11. Remove the aerator and soak with a 50/50 solution of white vinegar and water for about 15 minutes, and make sure to rinse the aerator off with water when completed.
If you are still experiencing the clunk I would next recommend replacing the diverter, please contact us back for any further questions.
Thank you for being a loyal Delta customer.
Best Regards,
Nicole

i need a Faucet Handle only for Foundations Model#: B4410LF - only the handle. how can i get just the handle?
Hi ar dub,
Thank you for your question about the Delta Faucet model B4410LF.
A replacement handle is Peerless part number RP44476.
You can purchase Peerless and Delta Faucet products from many local dealers and websites. If a dealer does not carry a specific item in stock, they should still be able to place an order for you. I recommend our store locator.
