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.

How to refill the bottle

Can't simply pour soap into top... it just overflows. Do you make some easy way to handle this?
Asked by: Clyde
Thank you for your question. We do recommend filling your soap dispenser from the top to prevent bottle breakage from taking the bottle on and off. We do offer a funnel that may make it easier when filling your soap dispenser from the top. Delta Faucet model # RP30395 can be purchased at your local retailer or wholesaler.

Soap Dispenser Instructions RP50781 - does black gasket (part #4) go on top of sink or underneath?

Picture shows gasket above sink, but instructions state to put through hole in sink - which is correct?
Asked by: Red
Hi Red, Thank you for your question! The gasket should fit into the base of the dispenser and will sit on top of the sink. Best regards, Jon

Is there a replacement pump replacement that uses foaming soap?

I have a new Delta kitchen faucet that came with this soap dispenser and would like to replace just the pump portion so I could use foaming soap that foams when pumping into my hand.
Asked by: Jack
Dear Jack, Thank you for your question. The RP47888 is the only pump made for the Delta RP50781 Soap/Lotion Dispenser. Soap Dispensers can use liquid dish soap, liquid hand soap, alcohol based hand-sanitizer,and even typical hand lotions. We do not recommend foaming soaps, because Delta soap/lotion dispensers are not designed to release foam from them. Best regards, Tanya

I need a replacement soap dispenser bottle for my faucet 4353-AR-DST. Is there a part number?

Also, the handle on mine does not look like the one in the parts list that is shown on this website. See photo.
Asked by: Tracy
Hi Tracy, Thank you for your question. The 4353-AR-DST was not offered with a soap dispenser. Only the (SS) brilliance stainless 4353-SSSD-DST, and the chrome 4353-SD-DST came with the soap dispenser. Based on your photograph the soap dispenser pictured is not a Delta product. Thanks, Dave

Do you fill this from above? If so, do toy unscrew the top?

Asked by: lm
Hi IM, Thank you for your question. To fill the RP50781 soap dispenser, lift the head and pump assembly out of the bottle and pour not more than 8 oz. into bottle. Best regards, Brandis

Black gasket placement on soap dispenser installation

The diagram photo and your previous reply in Q&A state that the black gasket should be installed on top of the sink. How is this possible, there is then a gap (probably 2 mm large, the size of the gasket) between the base of the product and the sink, the dispenser will not sit flush mount, water will definitely get into the gap. The mounting nut is tightly in place underneath, that is not the issue, the design seems majorly flawed. How do you get a flush mount installation to avoid water damage when the black gasket is preventing the unit from sitting flush?
Asked by: Susan
Dear Susan, Thank you for your question. The gasket for installing the Delta RP50781 Soap/Lotion dispenser is a thin foam white gasket. This gasket fits on the underside of the trim base, that sits on the sink/counter top. Best regards, Tanya
