Water experts please

Have you tried simply filtering the water and see if it makes a difference? I use a RV inline water filter for my wash water and pressure washer. I don't know how effective it would be but at something like 25$ at Walmart, I think it would be worth a try.

I order the ones off amazon the blue rv filters. 2 pack and I twist them together to make 1 big filter or 2 small ones. Don’t know if it does anything honestly. I have super hard water anyway.

I didn’t get a di quote but 100 gal aux tank with 3.5gpm pump was 450. It will have a line from my water heater to the reverse osmosis system to a tank that holds it I assume. I thought I would just be able to have a hose with to water but I think it has to store somewhere I don’t know.

I’m going to try just the ro water for a bit and see how I like it. Way better than what I use now I chase spots off chrome and glass

The reason you can't just have a hose with RO water like with DI, is it's a very slow process, you're basically filtering out molecules (I know people refer to DI systems as "filters" but they don't work like that).

What about mold that can tend to grow inside of a hose? Just yesterday I looked inside the garden hose in the backyard after I unscrewed the nozzle and the inside was lined with mold. I haven’t checked my Flexzilla that’s connected in the front yard yet. What do you guys think? Could that be a huge factor?
