We bought a very nice coffee maker (Flavia Creation 500), and placed it on rolling cabinet in our dining room. Location was not near any water lines, so we bought a 5 gallon water bottle that fits in bottom of cabinet, and also purchased this pump kit to provide water to the coffee maker. At first, the pump was not wanting to shut off... and just sat there humming once coffee maker was full and had shut off its inlet valve. But I found that if I adjusted water pressure higher (about 3/4), the pump shuts off perfectly when coffee maker is not needing water.
The only reason that I am not giving 5 stars is because the pump is pretty loud... but this may be due to the fact that I did not mount it, and it is just laying in bottom of the cabinet, next to the water bottle.
Overall, I am very pleased with this product. I do not have to constantly add water to coffee maker any longer, like I did with our Keurig!
