I’ve fairly recently bought a pumped RO system as I was fed up of the journey to spotless and wanted to produce my own water for less hassle.
It’s been working well but I’ve noticed the TDS is creeping up slightly after the DI cartridge that’s part of the system. I’ve not needed to produce much so far, probably about 400-500 litres.
It’s 200gpd and pumped as I have low water pressure (about 30psi). Tap TDS is around 250.
I’m very vigilant and have followed the instructions to the letter - including flushing before I start to fill and a bit afterwards aswell.
The problem is I don’t always need water, (small round which I’m trying to build up) so I’ve been producing and storing as I need it. I’m keeping my tank topped up, rather than letting it run out and filling from empty, but sometimes the RO doesn’t need to be used for a week or more, so it’s kept turned off and disconnected (I connect it to the garden tap as I don’t own the property so can’t connect it directly to the mains).
Could this be the reason the TDS has started to climb already?
I actually have two DI vessels which I was going to use instead (I know, the cost of resin), but thought the RO would work out cheaper. Just wondering as because the pure water I need is a bit more “as and when”/“on demand@ for me at present, would double DI be better for the time being?
Thanks for any advice you can give.
