Rated 5 out of 5 by from Easiest Working Faucet I’ve Ever Had This faucet works so easily that you don’t need much strength in your fingers. I had to buy new flex water lines since the copper ones were welded to the old faucet. No plumbers putty or silicone is needed. The faucet comes with a good fitting gasket and all you have to do is apply plumbers tape to the threaded connections. I love it.

Rated 5 out of 5 by from very easy Ordered the faucets without having dealt with the distributor before not knowing what to expect. I was pleasantly surprised when the faucet arrived very quickly and just as I had ordered. Very pleased with the process.

Rated 5 out of 5 by from Delta B512LF faucet This is a fantastic faucet on the proper type sink and vanity! It works smoothly and quickly with its single knob. It appears to have been made with the best metals and design. The previous faucet was an older Delta product that worked well for 30 plus years but had a more square design.

Rated 5 out of 5 by from faucets Just had a plumber install the Delta faucets today in the kitchen and one bathroom. Shopping with you was easy and convenient. I found just what I wanted to replace old Delta faucets that needed to be replaced. I would definitely shop with you again for plumbing supplies.

I need to replace the faucet handle caps for this model. I'm fairly certain this faucet is the same so the cap for this faucet might fit what I have. No one has the caps for the size faucet handle I have. I've exhausted my options. Can I buy here?

Asked by: Rick
Hi, Rick! Thank you for your question. The cap for the handle on the B512LF is not available on it's own. The RP41661 kit will include the handle, button, and screw. Best Regards, Rosanna

AFTER REMOVING THE KNOB HANDLE, I CAN.T GET THE HALFROUND PIECE LOOSE. I USED DW40 AND IT STILL IS STUCK. IS THERE A SPECIAL WRENCH FOR THAT?

Asked by: JIM
Thank you for your question. There may be hard water mineral deposits underneath your bonnet nut. We recommend soaking a towel in a 50/50 solution of white vinegar and water and then wrapping it around the bonnet nut overnight to soak it. You may also try a strap wrench to loosen the deposits.

Adjust Temperature

Is there anyway to adjust the temperature from this faucet without adjusting the hot water tank? If so, how?
Asked by: unclemoe8
Hi Unclemoe8, Thank you for your question. There is no temperature adjustment in the faucet short of the handle. If you have noticed a decrease in the hot water temperature there may be some debris blocking the lines. We recommend flushing the faucet to clear the debris. Here is a link to our How to flush a faucet video. http://www.deltafaucet.com/tools-resources/research/video-gallery/video.html?v=eWw-FdAezZY&cat= Also make sure that the flow from the hot water shut off valve is not being restricted. Thanks, Dave Thanks, dave

DOES THIS FAUCET COME IN BRONZE?

Asked by: CHUCK
Hello Chuck, Thanks for your question! Unfortunately, the B512LF is currently only manufactured in Chrome. Here is a link to all the single handle lavatory faucets we currently manufacture in the Venetian Bronze finish: http://www.deltafaucet.com/bath/lavatory/filter-results.html?finish=rb&handle=type-lav-singlehandle&sort=pricehighlow&function=bath-lavatory I hope this helps!

The specifications for model B512LF states "Solid brass fabricated body."  Is the housing for the faucet base and sprout brass that is chrome plated?  Or is the housing non-metalic?  Also are the tubes for hot/cold water hook-up copper?

Asked by: David
Hi, David! Thank you for your question. The Delta B512LF Faucet body is brass. The hot and cold supply lines are copper. Best Regards, Rosanna

The set screw on the knob of my “foundation “ model single handle faucet is loose and so knob comes off...how do I tighten it back on the shaft?

Asked by: Scuzmuffin
Thank you for your question, Scuzmuffin! The knob handle for this model actually has a hidden set screw inside the knob itself. This holds an adapter to the flat side of the stem tip and just underneath the cap of the knob is a phillips head screw that attaches to the adapter. Below is a link to your parts diagram for reference. https://media.deltafaucet.com/PartsDiagram/DPD-L-B501LF_A.pdf Best regards, Edward

What is the part number for a bonnet nut for this faucet? I cannot get the bonnet nut loose and I will probably damage it irreparably in removing it.

Asked by: Jeff01
Hello Jeff01, Thank you for your question. The RP50 Cap Assembly w/ Adjusting Ring should be the same cap/bonnet nut for the Delta Foundations Lavatory B512LF faucet. https://www.deltafaucet.com/parts-product-detail?modelNumber=RP50 Best regards, Tanya
