Is this really true? Can someone verify. If this is correct, I think I should get a booster pump. why waste water!

Use wasted water for other stuff. Jdigital and I used it for our laundry. Now the waste is used to water plants around at my parents house.

Depends on what your source water pressure is in the first place. Before you go getting a booster pump, get yourself a pressure guage and measure your input water pressure. If it is 60 psi or better, it's a waste of money to add a booster pump.

Seems like a strain on natural resources.

Like drinking bottled water... it takes 7 times the amount of water in the bottle to produce it.

If the few of you who mentioned it are recycling the water... good on yah... for the others that are dumping it down the drain... it's money out of your pocket everyday. Throw it my way instead.. I'll buy a fish ha ha!

I wonder... does anyone care enough to read signatures if you make them really small? I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.

Temperature makes a big difference too.
I had an inline thermometer on my household water supply just before the RO unit.
In the winter, sometimes the incoming water temp was below 5 C!
The RO membrane rejection rates (and GPD) are also based on an incoming temp of 23 C.
The colder the temp, the higher the rejection rate.
I have heard of some setups supplying the RO unit with a mixture of hot and cold water.

I have a vertex which is suppose to be 1:1 but I've never checked so I doubt it. If you're concerned about wasting water many people store the waste water and use to for other purposes. If you can find a use for all the waste water then your ration will be zero.

Sounds like a great idea...I think I'll try that, just need another saddle valve and a T.

Water is cheap though,...All you have to do is tap it before your meter, not that I'm doing that...
