Installing a flush kit on my RO system

[danielcassar]

Hi all, I have a 5 stage reverse osmosis system and lately i found that it is important to include a flush kit so that you keep the RO membrane clean and can last longer. I checked my system an after the RO membrane it has a black box between the rejection tube which says...

"Auto-Fluse Valve, Voltage DC24V, red (+), black (-), Flush time 18 seconds. (you can check the picture attached as well). My question is...should I still need to install a flush valve kit?

Thanks
Daniel
