Rated 5 out of 5 by from Replacement fixture for main bath With update of our main bath sink basin countertop, I had deferred to my plumber contractor the manufacture choice for the fixture replacement. I was pleased with the single handle Delta model similarity to the previous Delta product that we utilized to replace the original 2 crystal knob Delta (probably about 2010). So 15 to 16 years of service from the previous Delta fixture, AND the original fixture mentioned was installed w home contruction 1981. Not Bad longevity if you ask me

Rated 4 out of 5 by from Good faucet Looks great and I like that the handle is longer so I don't get water all over the counter around the faucet when I shut it off. But, not real thrilled with the water spots the finish keeps and I can't really get them out.

Delta Faucet 520-SSMPU-DST Finish: Stainless Steel

I installed a couple of these faucets for a customer, in their master. They had a decorative plug in the handle I believe. They lost one & I am wondering how I can get another one for them.
Asked by: David
Thank you for your question. Delta Faucet model # 520-SSMPU-DST does have a red/blue indicator button which can be purchased from your local retailer or wholesaler. The model number is RP73192 and they should be able to order it for you.

Hi Rosanna, it is not clear to me from the specs what the minimum size would be. Thank you

Asked by: JustK
Hi, JustK! Thank you for your question. I am sorry for the confusion. The hole size diameter should be between 1 1/8" to 1 1/2" (29 mm to 38 mm). The maximum deck thickness is 2". Best Regards, Rosanna

Hello - 11 years ago model 540WFMPU was installed during a bath remodel. It is now leaking and throwing out black residue from under the handle. Are parts still available? It seems discontinued.

Asked by: Paul
Hi, Paul! Thank you for you question. There still are replacement parts available for the 540-WFMPU faucet. If the faucet leaks, we recommend to replace the seats and springs and cam & packing. These parts are available in a repair kit, RP3614. Here is a link to the kit: https://www.deltafaucet.com/parts-product-detail?modelNumber=RP3614 You can usually find Delta faucet parts at any dealer that sells Delta faucets.

I bought this: Delta 520-MPU-DST but the box did not include a popup nor is there a lift rod on the faucet even though box label says popup included? Also, what is the difference between this faucet and the 520LF-WFMPU ?

Asked by: Em Westlake
Hi, Em Westlake! Thank you for your question. The 520-MPU-DST does include the metal pop up, RP26533. If this did not come with the drain assembly, we recommend to check with the store you purchased this from for a return/exchange. If this was an open box item or a clearance item and came 'as-is', you may have to purchase the drain assembly separately. Here is a link to the drain assembly kit: https://www.deltafaucet.com/parts-product-detail?modelNumber=RP26533 The difference between the 520-MPU-DST and the 520LF-WFMPU is that the 520-MPU-DST features our Diamond Seal Technology. This includes flexible, PEX supply lines. You can learn more here: https://www.deltafaucet.com/design-innovation/innovations/kitchen/diamond-seal-technology The 520LF-WFMPU is also Lead Free. This includes 3/8" O.D. copper supply tubes. Here is a technical specifications sheet for both units: https://media.deltafaucet.com/SpecSheet/DSP-L-501LF-WF%20Rev%20E.pdf https://media.deltafaucet.com/SpecSheet/DSP-L-500-DST%20Rev%20K.pdf Best Regards, Rosanna

How do I remove the aerator?

I'm trying to remove the aerator but no tools can grab that grey plastic aerator.
Asked by: Carlos
Hi, Carlos! Thank you for your question. The faucet aerator is cached so you will need a special aerator wrench. The aerator wrench is RP60730. Here is a link to the part: https://www.deltafaucet.com/parts-product-detail?modelNumber=RP60730 Best Regards, Rosanna
