RODI shut off valve question...

[Ruben's Reef]

Hi everyone,
I have this Aquaticlife RODI Buddie 50gpd unit but I would like to hook up the auto shut off valve. Did anyone knows how to connect this ASO valve on this unit? I look at some videos but it shows different units.
Thank you in advance.

I have the same unit but don't have an ASO, so I will be following along.

Same here. I want to know how to use this before I buy it. I have the RO buddy and the buddy booster that I am about to hook up.

So there are four connections on your shut off valve. One side has screws that you can take out to split the unit in half. The two connections on rhe side where you can see the head of the screw is your product side, the other two on the larger half are your feed side. So basically what you want to do is have the line coming out of your ro membrane that goes to your di cartridge spliced in on that side of the shut off valve, and then the line that goes from your pre filter to your ro membrane gets spliced into the other side of the valve. Double check that you dont already have a check valve installed on this unit, if you dont you'll want to put it between the output on your ro membrane and the shutoff valve to prevent water from backing up into the ro membrane and also creating the pressure in the switch to close off the supply water line. This video from brs probably explains it much better than I can. They're using a different rodi unit but the concept is the same.

Thanks Crabs. So the connection has to be made before the DI cartridge? The unit doesn't come with a check valve but the kit came with one. I watched that video before but I will watch it again when I get home cuz on my work computer the YouTube is blocked.

All the ones I've seen have been before the di cartridge. Whether or not you can put it after the di I am unsure

I will try with the BRS instructions and the @Crabs Mcjones suggestions. Thanks

Ok I got it. Kind of tricky but is working perfectly. Take about 20 to 30 second to the waste water to stop complete. Thank you all for your suggestions and recommendations.

yes it does take a few seconds, but not too long. that’s normal.

awesome that is correct, the pressure has to build up enough to activate the valve
