Reverse Osmosis System Flush Valve Kit Information


Product Manuals & Documentation

Flush Valve Kit for systems with 1/4" waste water tubing.




**Variations of this product can be found in many online stores. The version we carry is of the highest quality. Although this item is eligible for price matching under our Low Price Guarantee, please be certain the product you want to price match is the same make and model.





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.


Manufacturer Info

Captive Purity manufactures water filtration and water testing supplies for marine and reef aquaria. The brand is best known for their high-quality line of reverse osmosis filter systems and accessories. Captive Purity also produces refractometers for testing salinity, portable pen-sized meters for testing pH as well as replacement filter media for their RO and RO/DI filter systems.

Does the job

Experience Level: Beginner


Comments: 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

Comments: 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.

Needs Redesign

Experience Level: Beginner


Comments: 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.

Comments: 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.
