Rated 5 out of 5 by from Nice soap dispenser This is a very nice looking soap dispenser, not like a commercial one. Stylish and good quality.

Rated 1 out of 5 by from Awful Product I have two of these soap dispensers in my new build home and neither of them work any more. They are only eight months old. One of them does not work at all and only worked for about a month, and the other barely works anymore. We put all Delta products through our entire house because our builder said they were the best. I am VERY disappointed in this product.

Rated 3 out of 5 by from Handle doesnt reach far enough and doesn't hold enough soap Good looking soap dispenser - have been using it for about 3 months. Works fine, BUT - IMHO it doesn' hold enough soap (13oz) I thought twice i must not have filled it up all the way, only to have it overflow all over the eschelon. Also the handle does not reach far enough over and into the sink. Almost impossible to squirt soap into a pot or bowl, have to put it on a sponge first then let the soap go into the cooking pot/pan/bowl. Maybe I just do a lot of dishes. Looking for a new one right now!

Rated 5 out of 5 by from Nice, it works I wasn't sure it would match the faucet in color. (WHY does Delta have only two soap dispensers, neither of which match most of the faucets? Wanted one with a matching square base.) Fortunately it does despite a different name for the finish. And despite a squared off kitchen sink faucet it looks fine. The top of the dispenser is thankfully large enough and the rise in the spout doesn't interfere with using it with grotty kitchen hands.

Rated 1 out of 5 by from Not durable, breaks easily, expensive replacement This is the second time we purchase this soap dispenser and it broke again after 3 years. Does this have lifetime warranty and if so how do i get a replacement? I don't want to spend more money on this as this is now costs over $100, which is ridiculous.

Q&A

I ordered an RP47888 pump on Amazon for my RP50781-BL dispenser. The head from the dispenser doesn't fit into the top of the pump tube on the replacement pump. Amazon and your site say it is the replacement for the dispenser. Can you help.

can a cream type lhan soap  be used with this dispenser?

Asked by: Warren
Hi, Warren! Thank you for your question. Our Delta Soap Dispensers can use liquid dish soap, liquid hand soap, alcohol based hand-sanitizer,and even typical hand lotions. Foaming soap will pump from the soap dispenser but it will not foam. Best Regards, Rosanna

There's a loose black rubber gasket & also a white sealant attached the bottom of the base that affixes to the top side of the sink. The white seal seems to replace silicone. Does the black gasket still go above the sink, or below with the plastic nut?

Asked by: Bill
Hello Bill, Thank you for your question on the Delta Soap / Lotion Dispenser. I will be happy to assist you today. The black gasket should be installed below the deck between the deck and the mounting nut. If you ever have any questions, concerns, or require anything further please feel free to give us a call on our warranty line at 800-345-3358 and we will be happy to assist you in any way that we can.
