Specifications

Significantly enhanced the life of RO membranes and reduces membrane cleaning requirements. This flush valve kit when placed between the membrane reject port and the flow restrictor provides a high flow bypass to purge concentrated brine from the membrane housing and rapidly flush any particulate from the membrane surface. The flushing is best done just before the RO system is shut down by opening the FVK valve for 15–30 seconds and then turning the feed water source off.

RODI flush kit

It makes all the difference just add flow pressure valve to it and it completes your system. Great buy!

Does the job

Mine leaked on the restricted/non-valve side upon install. Simple matter of reversing the tubing to stop the leak. Already includes a flow restrictor which is a plus as I have a RO/DI system from a different manufacturer that has a different style restrictor installed. The time it takes me to make a gallon actually increased but the amount of waste water decreased so I call that a win.

RO Flush Valve Kit

Very easy to install. The installation instructions are a bit misleading. They instruct you to use the flow restrictor from the RO diaphragm, but the kit comes with its own restrictor built in. You still must remove the restrictor from the diaphragm. The restrictor from my RO diaphragm was better quality than the kit restrictor, so I used my RO restrictor.

MUST HAVE w/ RO/DI

easy to install. Must have for RO units. will extend the life of membrane which is the most expensive filter to replace.

Needs Redesign

Good quality but has a major flaw. I use a RO that has a line restrictor that has to be placed in the flush valve assembly. The line restrictor is longer than the tube on the flush valve so the flush valve will not work unless I replace all the tubing. Since I have to do that, I could have just purchased the 2 connectors and the valve and built my own flush valve assembly. They should make it long enough to fit the majority of all RO's.

Simplicity is Best

Great product. Quick installation...so easy even a cave man can do it. Look forward to many more gallons from my RODI unit before changing the membrane.

Peace of mind

If you’re like me and go the extra mile to ensure the highest quality of water then this is the last item in the quest. I like being able to know that I am doing my best to prolong the life of my filter cartridge by being able to flush it. This was so simple to install.
