Well water and RO/DI

[SpyC]

I recently moved and am not on well water. I have a brs 4 stage ro/di with water saver. For those on well water, how do configure your ro/di setup? I am thinking I need to add another stage or two or pre filter and another di stage. Do you run any special media due to the well water? Like co2 removal resin or anything like that.

Not special for me. I did start using a triple DI system and saved me a ton on resin.

I would also suggest triple DI. I go through anion resin so much faster with well water.

Yes, I’m almost 3-1

Same!

Thank you everyone!!

Some of the most common issues with well water are:

• excessive hardness
• iron
• manganese
• hydrogen sulfide

None of these issues play well with a configuration where you have two RO membranes plumbed in series. We would never suggest such a configuration to anyone without taking a look at their feedwater chemistry.

Adding DI stages may or may not be needed. Do you have high feedwater TDS? Do you have CO2 issues? Remember that neither of these issues is a "given" with well water. The term "well water" tells us absolutely nothing about the water quality - it only tells us where the water is coming from.

Do you know anything about your feedwater? Have you had your well water tested by a lab?

Could anyone recommend a specific unit/brand? I also have hard water and I’m looking to upgrade

Same, and it's easily recharged with lye.
