Hi, I've been doing a lot of research on this investment and have boiled it down to the following. I would appreciate any help or advice you experts might give, especially on sizing, valve choice and my strategy to treat the water problems I have. Purchase horizon is within the next 7-10 days.

Here goes:

Single family home, 4400 sq ft (1" PEX), 4.5 baths on city water, 4 people (2 adult, 2 children). Typical water use is under 200 gallons a day (55 per person). Max concurrent usage is typically 2 showers at the same time, rarely even that.

Water test results:

Hardness: 10 gpg
PH: 7.4
Iron: .7
Chlorine: 3 ppm

Approach:

Fleck 7000 SXT 2 cft GAC (to treat chlorine) followed by
Fleck 7000 SXT 1.25 cft softener

I sized the softener based on some online sizing help. I figure 32k capacity is fine for max flow, but i wanted a bit of a buffer at 40k capacity.

Appreciate any feedback on this plan!

Thank you
Kent
