  • Just what my RODI unit was missing! By Kevin on 3/10/2014

    I bought a 5 stage RODI unit used from a friend. It worked great but the continuous stream of waste water flowing after the float valve closed left me frustrated. I was under the impression the Auto Shutoff Valve would stop the waste, but it was only part of the answer. After adding this inline check valve between the output of my ro membrane and the auto shutoff valve, the water completely shuts off a few seconds after the float switch engages. I had to watch the product video for the complete float valve/check valve/auto shutoff valve kit to find out where it should go. The valve is sturdy and the tubing locks in solidly.
  • Good quality By Jeff on 3/2/2014

    I've ordered and used Murlok components for my RODI set up and all have worked well, including this check valve. I’ve used and returned cheaper quality components to my local hardware store that leaked.
  • Works flawlessly! By floridamixedreefer on 2/24/2014

    I just added this check valve to my pure water output on my rodi system. I already had the Auto Shut Off valve and float valve for filling my mixing barrel,, but I was bothered by the waste water continuously dumping down the drain after the float valve shut off. I added this check valve just after the y fitting merging the pure water out lines from my dual 75gpd membranes and just before the ASO valve. No more waste! I did notice that my fast flush bypass does not engage without the RODI product line being cracked open to release the pressure activating the ASO valve(I use a 90 degree shutoff valve right before my mixing barrel to keep the spills down when I disassemble for cleaning). This is understandable with my configuration and is not a deal breaker by any means. I need to buy some more of these to add to my DI output etc.
