Making my carbon/gfo reactor more accessible

[Jr'sReef]

I have my brs reactor on the outside of my sump held by two screws to a wood panel on the stand. I wanted it outside for ease of maintenance. Never had an issue.

Alright @Be102 let's get you through this, first of all, what you are experiencing with the RODI is 110% the way it is supposed to be. Before you had a capillary flow restrictor that was inside the line itself with no flush valve So it will always be restrictive on your waste flow. Now, you have a flush valve, this essentially bypasses the built in flow restrictor you have and allows the full pressure of your water wash over the outside of the membrane. This helps flush out all the nasty build up on the surface of your membrane and helps extend its life(which is the whole point of the flush valve). So ideally any time you want to make RODI water, open the valve on the restrictor and let it run for 20 orso seconds letting it flush all the nasty stuff off, then close it. This forces water through the restrictor and the restrictor doing what it does, restricts the flow so water is forced through the membrane.

So you’re saying the restriction thing that was in the line before was literally restricting my water by that much? Why’s that? It’s just gonna seem like I’m wasting a lot more water. Not that I mind just trying to figure where the other water was going all this time I guess.


So I leave it on “ flow” at all times until I need to flush where I put it close?

The restriction is necessary in order for your system to function properly. Your restrictor sets your product to waste ratio for your membrane, allowing x amount of water to push through the membrane (RO water) and x amount to come out as waste. Without the restrictor you will have a hard time making any RO water atall. And to function you want it set to flow (little handle parallel with line) to flush the membrane. And close it (little handle perpendicular to RO line) to make your RO water.

I think I was doing it the opposite. I think I was using flow as in flowing into my rodi... idk I’ll have to mess with it.

I finally got it. The flow / the flat way is the way turn it to flush the memebrane and then I “close it “ to make rodi. Makes more sense and explains why the speed seemed so different

So now to tackle the action of somehow adding this part of the fitting to connect to the elbows on my reactor. Idont need to have a little valve thing Like I do now cause I can finally put the ball valves into use... spent so much $ on ball valves not getting used ....

There you go! Yes when you purchase an RODI system they usually don't come with flush valves and when you first set one up it can definately throw you off

I have a manifold, and use Cepex true union ball valves. The quick connect fittings are screwed into the ball valve.

What’s the connection from soft tubing to the push connect? Is yours a screw on or

From the Cepex ball valve is 1''. There's a reducer (1'' to 1/2'') from the ball valve to the screw in end of the quick connect. The other side of the quick connect is a barb fitting; the soft tubing connects to that. Hope this helps.
