Q&A

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

Asked by: Mom Wilds
Thank you for your question. It is possible to switch from a crystal knob to a lever handle. The model number for the lever handle is RP42986. After you remove the crystal knob, there will be a connecter underneath that will also need to be removed before the lever handle can be installed.

my faucet is over 35 years old......does the replacement cartridge fit the older model single handle bathroom faucets? The one with the big plastic knob.

Asked by: Coloniamick
Thank you for your question, Coloniamick! Models that use the current DST cartridge can not work with the older ball and cam assemblies like the one used on this model. Similarly, this model can not accept a DST cartridge into the valve body. https://media.deltafaucet.com/PartsDiagram/DPD-L-B501LF_A.pdf Best regards, Edward

What material is this faucet made.

Many of the new faucets are made with plastic and other low quality materials. Is this faucet made of cast brass with chrome finish? Also can the flow rate be increased?
Asked by: KMB
Dear KMB, Thank you for your question. The Delta Foundations Lavatory model B512LF faucet, has a Chrome finished metal body. The crystal style knob is plastic, along with some internal parts. There is no way of increasing the designed 1.2 gpm flow rate of this faucet. Best regards, Tanya

I've lost water volume and pressure, I suspect the screen is plugged, I've tried to remove the cap that holds the screen in place but unable to remove it, any suggestions

Asked by: Randy
Hi Randy, Thank you for your question about the Delta Faucet model B512LF. I recommend soaking the area with a 50/50 mixture of white vinegar and water. This will help dissolve mineral deposits that can reduce the water flow and make the aerator to be difficult to unscrew. Please reach out if you have any additional questions!
