I upgraded to a 7 stage 150gpd unit, so up for grabs is my spectrapure 90gpd ro/di unit. Well maintained.
Recently replaced ro membrane, sediment, carbon and di cartridge on Oct 9th 2019. I have a new flow restrictor as well, not installed yet.
I have a booster pump hooked up to it but I'm keeping that. Pressure gauge is touchy. Works then doesn't. System operates perfect with 0 tds after di and 12tds after ro.
Located in Ramona.
$100 pm with number for pics if desired
