Comments: If your pressure is not at the high end this product may not work for you on the Spectra-Pure units. My pressure is at about 50psi, and the ratio out of the box is about 5-1 (Five waste to one pure). Part of this may be due to the fact that it is winter, and my water is a bit on the cooler side. If the tube were longer the ratio could be adjusted. I will try one with a longer tube and see if I can use this during the summer months.

Comments: This Flow Restrictor installed with ease and gave me the 4 to 1 ration i was looking for without having to cut it. I had bought a in-line restrictor and i wasn't working for me. I have the 75 gallon per day setup great buy!
