Hybrid RO/DI System Build

[ReeVo]

This is great information, thanks a bunch. I'm going to follow your setup. I just got all my packages in so I'll get to it in the next few weeks. In the meantime I'll go ahead and place my booster after the sediment and carbon filters. I'm on well water and it gets nasty very quick. I'm surprised I haven't ran into issues with it already.

Happy to help

The placement of the booster pump after the sediment filters is warranted for your source water. Booster pumps are resilient and can take a beating but we dont want to replace one after a couple of years if we can avoid it.

Check out our Reef/Residential RODI system. We've had this system configured in this way for 20+ years.

@ReeVo Hey man, I'm trying to place my booster pump after the sediment/carbon filters. Which line do I need to add it to? The Y fitting to the gauge is messing me up. Thanks.

@ReeVo I think I've figured it out. Let me know if you see anything wrong. The blue line coming out of the auto shut off, I just want to confirm that is the output that should be going to the DI stage, correct?

No worries man! Place the booster pump between the Y fitting and the filter.

Disconnect the tubing from the filter and Y fitting, run some longer tubing from the filter to the pump. From the pump back to the Y fitting.

@c4haskett That looks right to me! The blue line kinda through me off a bit but once i figured that is still your feed line, i knew it was correct.

BTW, whats the point of the T'ed off valve after the booster pump?

Thanks! Not sure, that's the way it came from BRS.

Dangit, just realized I tee'd off my drinking water 3/8 line in wrong place lol.

Thats odd. I mean i guess if you wanted to run another RO system or just have access to tap water, that would be useful. I would take it off and run straight tubing just to avoid any complexity and failure points.

No, that was my mistake. I Teed off there to go to my under sink tank for drinking water. I just fixed it.

Haha that makes sense now. Thankfully you noticed before you started drinking straight up tap water.

And the placement of the pressure switch is also correct. I forgot to mention that.

Just make sure to T off after any remineralizer/carbon water polisher for a second drinking source. If you plan on having only 1 drinking water source (faucet or fridge), no need to T off after the remineralizer/carbon water polisher

That is correct now! You're good to go!

That switch was the auto flush valve. My pressure switch is after the di stage on the output line. Where do I need to put that?

Ooh! Thats fine.

Is the flush valve on the clean or drain water side of the RO membrane?

It's on the drain side.

I believe the pressure switch needs to go before I made the tee, (output from ro membrane) to the under sink tank?

Yes correct! That way the pressure switch will activate with either the drinking water side and DI water side, and not just the DI side.

Great, thanks again. Very much appreciate all the time you took to help me. I should be good.. for now. Lol.

You're welcome bud! Enjoy the new setup.
