Over doing the RO/DI

I have a puratek system and highly recommend it ,simple and comes with all the bells and whistles http://www.jlaquatics.com/product/vt...+-+100GPD.html

Stupid as it sounds I started with 5 stages and was changing filters every couple months and was making water slowly, by adding pre-filter and DI stages and an extra membrane and booster pump my filters last 6 months and I make water really fast which is more efficient, stupid as it sounds.

I wasn't taking a pot shot at you simmer down lol
Yes my first ro/di unit didn't last long either just a simple unit 4 stages no booster pump I don't think I got 4months out of it so I bought the new puratek with the booster pump and its been over 6months and a lot of water thru it and still going strong ..... I would recommend buying one with a booster pump though as it helps with giving the proper pressure for the filters

I run 10 stages because I have to not because I want to, my water is 280 ppm out of the tap, like daplatapus said, if your water is less than 50 ppm then a simple 3 or 4 stage unit would suffice.

My water is also up there t 250 something and yet it still comes out at zero and its the same zero thru my 5 stages as your 10 I am sure your system is great though an may last longer but for me and simplicity I will stick with the puratek or something simple like that

Well i think i found my guy; http://www.reefsupplies.ca/online-st...ectrapure.html because we have excellent pressure here in the capital, good water no contaminants, i'll verify with city official whats the water purifying methods and that it. thansks for your input.

Knowing our government you probably have bottled water coming out of your tap, lol.

LOL Knowing yours i hate to see where it comes from LOL...

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?

While it does seem logical that more stages are better, it really depends on each user's source water. You need to consider TDS, pressure, temperature and other contaminants, that is 'non dissolved solids', or sediment. TDS means 'dissolved solids' and the only thing in your system that will remove them is the RO membrane. Adding a bunch more sediment stages before your carbon block & membrane will do nothing but add bulk (which you find a bother) to your set up. It will also reduce the pressure at the RO membrane resulting in slower pure water production.

If you're on a well with low water pressure & a pile of iron & other sediment, then yeah, get a booster pump & maybe add a sediment stage. Alternatively, simply change out the sediment stage more often, it's the cheapest component to buy and with a clear filter housing you'll have a good visual when it starts getting real funky.

If you're on city water treated with chlorine, TDS below 200 & water pressure of 60 psi or better, you can easily get by with a 4 stage unit. 1 sediment, 1 carbon block, RO membrane & DI stage. If money is no object, knock yourself out . Changing DI more often is not going to break the bank, but I've only done it once & it was a fiddly affair.
