Delta Faucet RP21908 Soap/Lotion Dispenser Pump Head

The pump is not the subject of this review it is the Delta/Amazon documentation. One of Delta's most popular faucet styles is the Addison Touch kitchen faucet, which I needed to replace the soap pump on. Amazon's page had a part finder at the top of it. The idea is great. I tried entering my faucet part number in several different ways, but no results were returned. Next, I did some web surfing to make sure that the fit was good. It was found across a variety of places, including on Delta sites, for Delta part number RP21908. As a matter of fact, this was the only Delta pump number I could locate. As a result, I could only purchase pumps and bottles or pumps, bottles and spout assemblies that I did not In view of the fact that it was the only option, I assumed it was correct. Although I was reluctant to pay $7 for a $2 part assuming it would be a drop-in replacement The replacement is complete. It was an error on my part. The opposite is true. On top of the photo you can see the original pump and spout head, and on the bottom you can see the RP21908. In addition to being too short, the new part had a larger diameter at the top, and didn't fit in the pump head at all. If the model number search had been accessible, I could have made a better decision if I had been able to read some basic dimensions on the Amazon page or the Delta website. It may have been better to return the part, but my only other option was to buy a whole new pump assembly for $45 or more, and then assemble it myself. I did not replace the pump, but instead fixed it. A larger piece of standard 1/4" PE tubing was used instead of the pickup tube after I hand-drilled the head of the pump to fit in the pump body. Despite the fact that it fits in the socket perfectly, the cord sits just a bit higher. My mistake was to assume that the only option was a good one after spending a lot of time searching for the right part.

I am glad we took a chance and bought the Delta RP21908 - it is perfectly suited for our needs! In order to snap it into place on the bottom of the soap dispenser tail piece, you will need to notch it. After I applied enough pressure to snap the top onto the pump, it worked perfectly. I used a small pair of pliers to hold the pump's top and to hold it in place. The new pump will hopefully last as long as the original Kohler pump did. Neither can be beat when it comes to price!.

I was unable to find a direct answer to this question, Therefore, I purchased this item for a few dollars. There is no point in salvaging it. I cannot use the Delta dispenser with this cap. Modified the frame a bit and got the pump in the head, but the whole body slid too far into the bottle, the straw pickup was too short, and the head poked too far out. I had a lot of fun, other than that. You can take a spin on the wheel and see if it works The person who needs to know which pump works with which body needs to develop a better system. The bottle of soap belongs to me. You are in good hands.

It was not possible to operate the pump. Instead of replacing what was broken, I decided to attempt to fix it. Due to their lower prices and better reviews, I spent my money on two Kohler pump heads. This was an issue of their thickness. Since I noticed that users of older dispensers, who had problems with this pump, had success with it in the reviews, I decided to give it a try. I have come to my senses! I found it to be helpful! This is a great deal because it's much cheaper than a brand-new.

And I was even more pleasantly surprised when it fit into a 15-year-old Delta. This has nothing to do with It only took me a few seconds to take out the old insert and replace it with the new one. As if it had never been used. that the only problem people might have is making sure their pump is compatible with this insert, but after a quick measurement and glance at the photo, I was convinced it would work. No defects were visible on the insert, and it looked well-made. It was done. The reasons I didn't do this a year ago are beyond me, even though I began having problems then.

My Delta kitchen soap dispenser's pump was going to be replaced with this. To ensure I purchased the correct item for my faucet, I was extremely careful when selecting it. There was a specific mention of my model faucet in the description. The pump does not fit in any way, however. It's not possible. Unfortunately, I had already opened the package and the plastic packaging had been discarded by someone in my household. If I had not returned it, I would have said so.

My Delta Pilar faucet has a single handle, and I have a soap dispenser with it. I can't seem to get the liquid soap to work in the soap dispenser. According to the information I read, this would fit, so I ordered it. I don't think it will fit. Sending it back is not my favorite thing to do. This is my second attempt to buy a gearbox that will actually pump oil (please let me know if you get it).

The pump mechanism was supposed to replace the original delta pump mechanism, and it fits perfectly! Because this part was not available at local stores, I'm thankful to Amazin for carrying it. We liked the new pump because the original produced too much soap at every depressing of the head, and this new one produces less soap at each depressing, which we like since we don't want to waste too much soap. The Victorian styled faucet I had been using has now been discontinued, so I'm ordering more to have on hand. The price is very reasonable at this point!.
