Which RO?
« on: March 19, 2015, 07:49:07 pm »
Hi guys,

I am currently looking to get a new RO as my current system is no longer keeping up.

Could anyone tell me which RO system reduces TDS the most before DI, my current input TDS is 370+ so I want to get that as low as possible before DI to save on resin.

Is my best bet a 4040 or PRF RO or maybe something completely different?

Cheers, Gary

4040 but use a booster pump, change pre filter often to preserve membrane should get your water TDS to around 15 maybe single figures

Yeah 4040 for sure, out water is 470 on average and you'll need a 4040 to get it low enough to make resin last...
