Review on ISpring RCC1UP AK Performance Filtration Remineralization by Nick Worley

Easy assembly and flushing. However, one strange problem and two big problems. 1) Big problem 1. With the UV plugged in, the first glass of water tastes awful after sitting for a while. Turning off UV fixed the issue. 1) Major problem 2. The flush valve on the drain line makes a very loud hiss when the pump is on. I hope this is just a defective valve and not a sign of general quality. 2) Strange problem - when the pump is running, water is thrown out of the drain line in 3-4 large bursts before the flow is reduced. Even after settling, the water leaves the drain at a good rate, and even when the tank is empty, it still leaves the tap fairly quickly. I hope this is related to number 2.
