RO/DI unit making too much water...

Reefer94 · 07/12/2010, 09:39 PM

I have a 50gpd RO/DI unit. I let it sit in the garage about a year while I moved around, needless to say I just replaced the filters.

Problem is, I'm getting waaay to much flow. It seems like I'm getting 3-4 gallons per hour out of my 50 gpd filter. Unfortunately, no TDS meter... so cant check to see if it's doing its job.

Off hand, anyone ever had something like this happen? And what could it mean? It's the Mighty-Mite from Air, Water & Ice, filters are less and 1 day old.

Do you know what your psi is?

I switched to a 75d a day membrane from a 100g and I have low pressure. unit now makes much more water measured at 0 out of the membrane.

the key thing is what does it read, you need to get a real TDS meter.

No... yet another factor I'm not sure of. Would PSI being to low/high cause an effect like this? Is there a cheap way to find out?

Yeah I need to just get a TDS so I know whether or not it's good water, or if it's somehow missing some filtration.
