Rated 5 out of 5 by from Looks great and buoy to last! I’ve enjoyed having this faucet. Fully functional and easy to use and easy cleaning. Doesn’t stain. Nice comfort grip and built to last. I don’t think I’ll be replacing it for many years as long it doesn’t rust or break.

Rated 3 out of 5 by from Pretty Looks and works well, however its pretty small compared to our old faucet. I would recommend this faucet to anyone looking for a small shiny faucet.

Rated 4 out of 5 by from Standard faucet, gets the job done! Overall I am happy with this faucet. The installation was a breeze and the instructions were very easy to follow. I really like the chrome finish and simple design! My only complaint is that the water pressure is a bit lower than I’d prefer.

Rated 4 out of 5 by from Always count on Delta This is a brand you can count on. Delta backs all of their products. We won't have anything else in our house. We replaced the bathroom faucet with this and it's so much better now. This was easy to install and really looks modern compared to what we had. It is easy to clean around the base. The water flow seems consistent too!

Q&A

Is there an aerator with a greater flow rate than the one that comes with B510LF? Is the original aerator that comes with it 1.2 or 1.5 gpm?

Asked by: Bill
Dear Bill, Thank you for your question! The Delta Foundations Lavatory Faucet B510LF faucet comes with a 1.20 GPM at 60 PSI aerator assembly. The RP61340 is the 1.50 GPM at 60 PSI, for this faucet model. https://media.deltafaucet.com/MandI/86607%20Rev%20B.pdf Best regards, Tanya

Is the stopper brass

Is the stopper assembly brass? Is the unit well made of brass and metal parts? I would like a single handle style classic well made out of metal parts, not cheap plastic that will break. Thanks, Ray
Asked by: Ray
No, it's plastic. It seems to be durable though, and scratch resistant.

What is the difference between B510LF and DB510LF

Asked by: Steve
Dear Steve, Thank you for your question. The B510LF is the Delta Foundations Single Handle Centerset Lavatory Faucet. This is a full lavatory faucet with a pop up assembly. The "D" in front of the model DB510LF, maybe a dealer's brand identification coding, for their ordering purposes. Best regards, Tanya

On the specs, it states the "Max Flow Rate" on this faucet is 1.2 GPM. If I bought a 1.8GPM new replacement aerator, would the faucet emit 1.2GPM or would it increase to 1.8GPM ?

Asked by: JThomas
Thank you for your question, MThomas! The aerator restricts the maximum flow rate of water from the faucet. A maximum of 1.2 gpm @ 60 psi, 4.54 L/min @ 414 kPa is the federally mandated flow rate for this model as it is an EPA WaterSense labeled product. Changing the aerator will increase the flow rate however you may want to check with local legislation to be sure this will be complaint. Best regards, Edward

Asked by: DanK

Would the pressure increase substantially by changing the aerator from a 1.20GPM to a 1.8GPM. When they installed this unit, I was not aware it was a water/sense unit but even the installer mentioned water pressure was really slow. 

Asked by: Pick1944
Hello Pick1944! Thank you for your question and we are happy to help! The Delta Single Handle Centerset Bathroom Faucet Model B510LF does not have the option to change the GPM of the aerator, unfortunately. This model has a GPM of 1.2 GPM @ 60 psi. We recommend flushing the valves of the faucet and the supply lines to increase flow. With any further questions or concerns, please do not hesitate to reach out to us directly.
