Over doing the RO/DI

[MarieH]

I live in Verdun, suburb of Montreal, my water is 148 tds from the tap. I got an aquasafe for price point and free ship. I bought the faucet adapter because I'm an apartment dweller. Tds is 000 after 7 stages. I don't mind shelling out for the resins once a year. I just find all the cartridges piled up together a bit of a bulky bother but the water is good and I think if there's more stages you can go longer between resins?
