Im in Manchester and I swear my PPM is getting higher this last year or so. I used to be able to go 5/6 weeks before changing my DI vessels but now Its like 3/4 weeks.
It reads at about 50 out of the tap now.
Can anyone give me some basic advice on Reverse Osmosis? My current set up is just 2 large DI vessels but thinking I might need to introduce RO as well? I actually have no idea how it works
