Champagne bronze faucet
It's very attractive; however, water spots on it have to be constantly cleaned.

Perfect for a powder room
This is a great faucet. It's trim, yet stylish and was easy to install in an existing pedestal sink.

Beautiful Delta
I ordered in champagne bronze (Delta's gold color). It's prettier in person than in the pic. I haven't installed it yet but I know we'll love using it as much as we'll love looking at it!

Great product
This faucet is great. Looks good and you can feel the quality when you turn it on/off. It wasn’t the cheapest, but it’s the best. Looks lovely with our copper sink.

High quality
Love the Delta Dryden faucet in polished nickel! Kind of chunky, but it works like a charm with great water flow and the finish is beautiful.

Q&A
Can I attach rigid chrome supply lines to this faucet?
This facet will go on a pedestal sink. The pedestal does not sit flush to the wall which leaves the supply lines exposed. I want to attach rigid chrome supply lines to the faucet to make it look more pleasing than the existing flexible tubing
Hi Sybaris,
Thank you for your question. The supply lines may be shortened and connected to a rigid supply line. Please refer to the Custom Fit section of the Installation Instructions.

However, we also have decorative covers available for the PEX supply lines.

How much space behind faucet is needed for the pull rod on the 551-dst?
Many of your faucets require 2.5 inches from the center of the sink mounting hole to the back splash panel. This is so the push rod that opens and closes the drain can operate properly. This item is silent on this issue. I have a sliding mirror and the frame extends out, leaving about 1.5 inches rather than the 2.5 inches. Can I use this faucet? If not can you recommend similar one handled items that would work?
Thank you for your question. When using Delta Faucet model # 551-DST, your 1.5 inch distance to the backsplash will work with this faucet. You may have to adjust the strap to the pivot rod when installing the pop-up assembly.

can this product be installed with a undermount sink?
Yes, that's what we put ours with and love the way they look together.
Date published: 2024-03-28
Can I get this without the drain pull up on the back?
yes

Is there video on replacing the Value Assembly ( PN RP50587 ) on the Dryden 551 series faucet ?
Thank you for your question, Charles! First, turn the water off at your shut off valves. Remove the handle with the provided allen wrench and unscrew the cap and bonnet nut by turning counter-clockwise. The cartridge simply lifts out of the valve body and replaced with the new cartridge. Re-install the handle and turn the water back on to test the faucet. Below is a link to the instructions that come with this cartridge as well as a How-To Video that shows how to make this repair on the Non-DST version of your model and cartridge which will essentially be the same process.

I would like to install the Dryden single lever faucet on a 3cm granite countertop.. Will this work?
And what is the minimum distance needed between the center of the single mounting hole and the backsplach needed for the pop-up drain lever to work with ease?
Hi Carol, Thank you for your question. The model 551-SS-DST has a max deck thickness of 2-7/8". The faucet can mount to 3cm granite. The minimum recommended clearance to the backsplash is 2-1/2".
Thanks,
Dave

Replacement Cartridge - So we've run into an issue where there is water leaking under the handle and it appears that we just need to replace the cartridge. However, we want to make sure order the correct part. We ordered the Delta Faucet Nyla Cartridge?
Hi Ppada99,
Thank you for your question. The RP50587 is the correct valve cartridge assembly for the Delta Dryden Lavatory 551-SS-DST model. Please see the below parts diagram for this faucet.
