Rated 3 out of 5 by from Love this, but.......... I bought this (along with the matching pullout faucet) 6 years ago. The pump was always a little "flimsy" feeling when pushing down, but soap dispensed and it would pop back up, so I dealt with it. Now the time comes that it doesn't pop back up. My main gripe is that I can't find a replacement pump for it. Seems silly to have to buy a whole new dispenser when the rest of it is still in good condition.

Rated 1 out of 5 by from Soap dispenser never springs back! The soap dispenser has never worked. It presses down once and never springs back. Very poor design. Purchased this faucet mostly because of the soap dispenser feature and now I have a big bottle of dish soap on my counter again! Not happy!

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.

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?

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
