I thought I should break this out into a new thread since I've decided I'm going with the Fleck 9000 SXT vs. the metered unit. I'm looking to order the system soon, but I want to get unbiased opinions on what capacity and size I need before I purchase.
Hardness of the incoming water is around 27-30gpg. No iron, <0.5ppm chlorine, trace amounts of other contaminants. (City water).
The problem I'm having figuring out which size to get is based on current vs. future needs. Currently, I'm the only one living in the house, occasionally having anywhere from 1-6 other people "living" here over weekends and whatnot. So for my water situation currently, it seems that the 9000 SXT twin-tank 48k gr capacity would be a good choice.
However, it seems like if I end up having 4+ people living here on a consistent basis, the 48k gr capacity will not be very efficient, and will regen every 3-4 days. Am I correct in that assumption?
The house is 4 br, 2.5 bath with the potential to be 5 br, 3.5 bath with a finished basement. 3400 sq ft, so there's more than enough room to have potentially 5-8 people living here once I have kids. The price difference to go up to the 64k gr twin-tank setup is an extra $170. I'm starting to think that it would make more sense to just bite the bullet and get the higher-capacity setup right now, rather than need to upgrade tanks in the future at a higher cost.
So my questions I guess are:
- Am I correct in looking at these capacities (48k vs 64k)?
- Am I correct in assuming that upgrading tank capacity in the future (with the added cost of extra resin needed) would be much more expensive than the $170 up-front costs?
- Is there any problem in having the much higher capacity now even though I would only really need it on occasion?
- As long as I'm getting the SXT, if I'm not using capacity, what's the longest amount of time I should let water sit in the tanks? I've read anywhere from 9-14.
Thanks in advance for any advice you can give me. Being my first house (and first experience with water softening), I'm in desperate need of expert opinions from people not trying to sell me stuff.
