Rated 5 out of 5 by from Matches my new faucet This filled the hole left in the sink from the old hose sprayer. I got a new one handle faucet with a pull out hose that I love. This matched the hole size, the finish on faucet, and clears my counter from the old soap bottle.

Rated 3 out of 5 by from Delta RP50781AR I bought the faucet and soap dispenser together a little over a year ago. I love the faucet but the soap dispenser has broken. The pump just kinda dangles now, unusable since I can"t get the replacement part.

Rated 2 out of 5 by from Soap Dispenser No Longer Works I noticed several months ago that the soap dispenser was not working well. At first, the pump was just difficult to push down and very little soap was dispensed. However, the valve now pushes down, but doesn't pop back up. I took the pump out and cleaned it well; however, after putting it back together, nothing works at all. I tried to match pictures of the plastic tube to Delta parts, but my tube doesn't look like the only one that is being sold as a replacement part. What are my options? I love the faucet, but really hate this soap dispenser.

Rated 2 out of 5 by from poorly made plastic I bought this faucet and love the faucet but for the price it is disappointing that the soap dispenser is plastic. Mine came with a damaged area on the flat surface. looks like a flaw in the finish, very noticeable. its a shame for this price.

Rated 3 out of 5 by from Good faucet, bad soap dispenser. I bought the whole faucet set in brushed nickel. The plastic housing inside the soap pump head that holds it in place broke and now is unusable. I like the faucet, but the pump is made poorly.

Rated 2 out of 5 by from The dispenser is getting harder to use The soap dispenser started out okay, but soon started getting harder and harder to use. After pushing the dispenser down, it takes longer and longer to come back up. I followed the instructions and cleaned the dispenser with hot water to try to clean it out, but it hasn't helped. The dispenser when pushed down still take a long time to come back up and little soap comes out. I am not sure what to do, repair or replace? I would also like to find out how to get a soap funnel to fill the unit as mentioned in another review.

Rated 5 out of 5 by from soap dispenser I love this product-instead of dish soap- since I most often use the dishwasher, I have hand soap in it. I do suggest a funnel for filling if what you are putting in is thick-will make it easier. I love not having additional soap dispensers on the countertop.

I have the RP50781AR Soap/Lotion Dispenser that we bought new in January 2014. It won't pump now. I've taken the head with the tube out and washed it with warm water. The white part with the spring in it appears to be stuck/frozen and won't pump. Any idea

Can the head be swiveled left or right to be out of the way?

Asked by: Carol G
Thank you for your question, Carol G! The head of this soap dispenser is not attached and so it does swivel but can also be lifted up off the unit for easy above-counter refilling. Best regards, Edward

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.
