RO question Please help!!

[Josh23]

I just timed it.

For clean RO water to fill 1 cup or 250 ml it took 8 minutes
For waste water to fill 1 cup it took 5 seconds.

These seems a little fishy to me.

If it is to make 24 gallons per day it would have to product 4000 ml per hour.

mine is making about 60 minutes / 8 minutes = 7.5
7.5 x 250 ml= 1875ml.

That means that the production is almost cut in half from what is advertised.

Waste water on the other hand is at 60 minutes / 5 seconds= 720
720 x 250 ml =180,000 ml which is equal to 45 gallons per hour.
Thats alot of waste water.

Does this seem right to you or is my math off.
Either way its crapy and I think RO/DI units suck.
