RO/DI unit with hard water

[SaltySam09]

Hey, I've been looking into getting an RO/DI system for a while now, but I am concerned that my hard well water will ruin it to fast to be worth it.
Does anyone here have hard water? If so how did it effect the RO unit?
Thanks

You can do a water softener first or just not worry about it since that is what these are made for. You may just have slightly higher rejection rate.

Many with hard water have a whole house filter for it & run the RO afterwards.

I have hard water off a city well system. 5 stage BRS with a booster pump.

My house has a water softener, but the water still leaves a dusty white residue.

I just moved from well water but had very hard water myself. I installed a DuPont whole house filter and then thru softener to the RODI unit.

is it iron or whats the hardness in your water source. iron? TFC, TFM, or CTA membrane? if CTA are you using carbon prefilters? best method is to soften the water before it hits your RO membrane. Hard water will choke a tfc or tfm membrane pretty quickly do you backflush often?
