Every so often you come across a simple, yet ingenious product that makes the reef geek inside you just smile and glow and the nifty combination RO/DI flow restrictor and flush valve by Purely H2O is just genius. Available in 50, 75, 100 and 150 GPD models, they aren’t too much bigger than a regular in-line flow restrictor you normally see on the market and it eliminates the need for the typical flow restrictor and the separate branch for a flush valve to keep your RO membrane clean and happy. Best part about it is the price – $12.95 is the MSRP for this little beauty. Just genius!
