Rated 4.5 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Good product, little expensive I had to try 2 times before the cartridge fitted into the old soap pump but once into place work just fine. A little bit expensive for just a piece of plastic though. March 10, 2015
Rated 5.0 out of 5.0 by Pump works like new! Works like butter now. Our old pump was very hard to push down and would not maintain a prime and would barely deliver any soap even after several very difficult pumps. Installed the new pump and straw and I was amazed at how easy it was to pump and how well it worked. It was a bit difficult to pull the old pump out. My recommendation is to pull the pump from the head with constant pressure and at the same time wiggle the pump back and forth to help the o-ring seal of the pump separate from the pump. Once the old pump is out of the head, flush the head with hot water until all the old soap is flushed out. Lubricate the o-ring on the new pump with a little soapy water and push it right together. This is how I went about replacing the pump, it works like new now. I rated it difficult to install as a CON, this is due to how difficult it can me to pull the pump out of the head. If you are not prepared for it to be difficult to remove, you might think the pump won't separate from the pump. December 31, 2014
