"All RO water waste water because it discharged 3 glass of water for every 1 glass of RO water (3:1)" - some commented
My answer:
Discharged water is true because it's an auto wash process but only during the production of RO water
3:1 not sure because never measured before but I doubted it because IF true then the water bill should increased at least by 30% or more.
There were no such increase!
The water bill in fact have NONE or NO Significant increase at all.
Using water to wash dirty clothes are very common.
Using water to wash dirty floor are very common.
Water is commonly use to wash dirty things.
so
Using water to "wash dirty water"... O.K lah
We waste more water than the Elken Ken RO System
i.e
washing car
washing plates
washing floor
taking bath
brushing teeth
watering the plants
acquirium
others...
In other question...
Do you want these?
Thus, just let the system run accordingly. Don't listen to salesman who try to confuse you.
If they can't convinced you, they will try very hard to confuse you.
