I had seen someone write that the water pressure did not increase. They probably did not remove the pre-installed restrictor which the instructions tell you about. So if you're reading this, and think all these great reviews are bs... they aren't. Some people just skip instructions. I was impressed with the pressure gain after I swapped to this, though I do wonder if my water heater can keep up with how ridiculously powerful it is.
