Primo RO Water Refill at Walmart

I've never investigated, but is a low volume, tabletop softener/RO system a possibility? May be units on the market for all I know. I'd be willing to run with a 1:1 waste ratio, but 4:1 was always a deal breaker.

As someone said, use a permeate pump in the system. I used to run water thru my system and it would take so log to get water until i got the pump and changed the RO filter, now it pushes about 4 gallons an hour of RODI water to my kettle and sparge tank.

That's good. But even at 1:1 you dump a gallon for every gallon you use.

That's an important consideration, as many people live where water isn't so cheap (e.g., CA and desert SW).

For context: a single 12 minute shower with a typical 2.5 gpm showerhead uses 30 gallons of water.

Permeate pumps work only on systems equipped with a pressurized storage tank.

I wonder if you're talking about a booster pump?

A tabletop softener? Nothing on the market that I'm aware of. There are some manual softeners but even then they are bigger than "tabletop."

And for additional reference, a teenage boy getting ready for a date with his new girlfriend uses about 80 gallons

Beide sind richtig. Both are correct.
Also correct that folks who are committed to less water usage can save 30% or more with a low flow shower head. About 10 of those 30 gallons. Further conservation by wetting yourself - turning the water off and soaping up - then turning water back on to rinse. Not for everyone, but may become a need if water scarcity prevails.
