ro/id placement

[killingseed2000]

going to move my reserve tank. from ground level to about 8 ft above ground level. basicly on top of of a new room i made in the house. the ro/di unit is currently mounted higher then the reserve tank. but in the new setup i am wondering how the ro/di unit will work with is about 6 ft below the reserve tank?

any doing this now? anyone have an comments on weather i should raise the ro/do to a better hight.

It won't make any difference you can see. 6 vertical feet is only a 2.5 psi pressure drop which if you have good pressure is nothing.

You should be fine, it's pressurized.

Yes it is pressurized but changes in head pressure will effect performance, not only GPD but also rejection rate. 2 psi isn't much but when you play with the calculator located at the top of the page here you will see the effects of pressure and temperature on GPD.

I can also post a link to how pressure and tap TDS effect what is called osmotic pressure if anyone is interested.

You'll be just fine, my ro/di sits below about 5 feet and pumps out water no problem. I do use a pump, but only because my city's water pressure is terrible.

My RO unit sits about 4-5 feet off the ground, and pushes the water all the way up into the ceiling, across the ceiling grid, and into the garage. I get plenty of clean water still coming out.

thanks for all the feedback. i have been renovating for some time and its one of the last things i need to do in order to finish closing walls up the last couple of walls.
