RODI Unit producing A LOT of waste water, but only drops of filtered?

[Brooke24]

My new rodi unit is producing a crap ton of waste water, but a few drops of filtered? Help!

Is your pressure under 40psi? If so that’s might be your problem.

Yeah it is. How do I increase that?

Booster pump. Also if you have a flush make sure it's not set to flush (produce more waste than product).

Is there a cheap good one you know about? I’ve invested so much time and money into this thing, and don’t wanna be wasting my money haha.

agreed with above - you need a likely 50-70psi pressure for your membrane to work right. you will produce much more waste water than clean (and why some folks run the waste a second time through (another membrane)). sorry i couldnt follow your water lines in the pics... the angles combined with my wine consumption...

If you have low pressure it’s not a waste, it’s required. If you don’t have pressure you can’t force the water through the membrane

Haha you’re all good!!! Know any cheap, good booster pumps?

Alright! Know any cheaper side but good booster pumps?

semantics? it would still be going out the waste line..

i had a smart buddie a long time ago.. there are probably cheaper out there.

If you have no pressure you will not make the stated product water amount and the unit will run way under optimal efficiency

Nice! It’s on sale at saltwateraquarium.com for 116.99, and I won a 5$ gift card from Them so it’s about 110$! Not bad, but I’m close to buying sand and rock now so that was a unforeseen setback haha. Thank you so much!

Aquatic 6800 or 8800

Actually- I just adjusted my system, and it went to about 45 psi. It was the flush valve, I had it on lol! Thank you guys ! There is still

There is a weird sound coming from my unit though... anyone have ideas? It stopped now, but it was happening a second ago

 

[Brooke24]

That look about right???
