Rated 4 out of 5 by from Soap Dispenser Initially, I called customer service to determine which finish I needed to order. I could not determine this from the pictures. We needed what I discribed as brushed nickel. We received a chrome looking part. I called Customer Service to return part, and this rep said that we needed the stainless steel finish. He expedited the order and we received within a week. We then returned the original shipment and our credit card was promptly credited with original purchase price. My wife was happy and therefore I'm happy.

Rated 4 out of 5 by from delta pump This was exactly what I needed. The old one that I bought back in 2001 corroded. So I was in a panic that I wouldn't be able to replace...but I was wrong. This was the exact part.

Hi, I bought the two recommended parts, the soap dispenser head and bottle RP21908 and RP21904. The dispenser head seems to long, does this need to be cut to fit the bottle?

In general my kitchen faucet and sprayer are a very nice product. Why would the long thin part where the soap exits the dispenser, literally disintegrate where it is attached to the pump?

Asked by: mlc46
Hello mlc46, Thank you for your question regarding the Delta Soap / Lotion Dispenser - Pump Head. I am sincerely sorry to hear that the spout of your dispenser is disintegrating and I apologize for the inconvenience this has caused. There are a few factors to consider for why the material of the dispenser is disintegrating. The protective finish present on the soap dispenser should have protected the material of the dispenser, although if a harsh cleaner has been used on it, it may have worn the finish away. Another possible reason for why the material has started to disintegrate could be that water was present on the dispenser for a prolonged period of time without being dried off. Again, I am very sorry for this issue and I am happy to help you today. If you could please respond back to the email I sent to you with a few photos of the dispenser in full as well as your contact information, we will be happy to assist you further with resolving this matter or if you prefer to discuss this issue further over the phone with us, please do not hesitate to give us a call on our warranty line at 800-345-3358. Thank you, Brandy

Is this price of almost $60 for the complete dispenser assembly? Can't be for just the small head assembly, can it?

Asked by: Joe
Hello Joe, This part number is for the entire pump head minus the mounting, internal pump, and bottle. Unfortunately, the nozzle on the pump head is not a separate part.
