Most reverse osmosis systems will make a slight whining sound after water is used from the storage tank. Ha! Furthermore, some pumps have an onboard air compressor that produces an additional hissing sound while running. The system relies on that flow meter when in Flux-Control mode, so the noise was untenable. Membranes may also last up to three years, but it is best to check with the manufacturer for specific warranty information. Test this with a full tank of water while the tank valve is open.
