RO/DI in Phoenix Metro - How many stages?

[GreenbriarManor]

Hey all,

Setting up my first tank and trying to figure out my RO/DI system.

I'm in Scottsdale with a TDS reading of 485.

Was wondering how many stages you are using here in the Phoenix metro area.

Thanks!

This is the one I use. Been very happy with it. 4 year old membrane still good. Just have to remember to flush before and after use, make at least 30 gallons per use, and change filters on schedule. I take it a step further and run the faucet in which the water supply is tee'd for a minute or longer during the summer.

Mine is a 5 stage from BRS. 75g per day membrane. The TDS of me inlet water ranges from 450-500.

Mine is a BRS 5 stage, dual 75 membranes. I have an auto turn on/off Spectrapure system with the high and low floats with a booster pump. I can get 200+ gallons a day with a 1:1 DI to waste ratio. My house also has a whole house charcoal filter and softener. I use potassium cubes vs sodium in the softener. Last check my TDS was over 650 during the summer months.

I currently have 2 DI stages, but I am going to be switching over to a 3 stage DI with the separate cation, anion and dual resins. I have all the parts, just need to get it installed.
