iSpring 500 GPD Side-Flow Reverse Osmosis Membrane Housing (part of RCS5T) #NS15

I purchased this housing along with its corresponding 500gpd membrane to upgrade my 100gpd system. The municipal water for my business left water spots all over the sinks, toilets, made terrible ice and overwhelmed the dishwasher rinse aid (even at maximum rate). I purchased a pressure tank, a small diaphragm/on demand water pump and a 20 gallon RO storage tank. After adding a check valve, the system works flawlessly. Now, the dishwasher cleans everything completely, the ice doesn't have a funky look or taste, and the sinks & toilets do not have a white mineral film on them. Very happy with this product and definitely recommend it.

This thing leaks, not a fan of ispring
