Kinetico has their own control valve, it is centuries old water power, non-electric. Usually they require a prefilter to prevent 'dirt' from getting into the control valve and stopping it from counting down the gallons which prevents it from regenerating.
You never want to use a softener that requires the maximum salt dose for the volume of resin, nor run a softener to exhaustion before regenerating it.
Hard water wears clothing and all other fabrics out long before they should have to be replaced. Softening just the hot side is not a good idea IMO. Mixing any hard water with soft water and you have hard water. Soften all the water to all fixtures and get the many benefits of softened water.
Renting a softener isn't a good idea IMO, you're throwing money away. Search the internet and newsgroups for info on softeners and go from there. If you buy over the internet you can save from a few hundreds to a couple thousand dollars and get equal or better quality than a local dealer. And sttay away from big box store brands unless you want to replace the softener in 2-6 years. Look for a softener with the Clack WS-1 or Fleck 7000SE control valve. Search for them inside "". They are the best for a DIYer that wants to be able to replace a part if needed. Neither require control specific special Fleck tools like the Fleck
5600, 2510, 9000 and 9100 controls do.
You do not need a plumber to install a softener, unless you live in Mass. where homeowners are not supposed to do any of their own plumbing..... Any DIYer can do it if if they have the desire and will buy some basic tools. It's very simple and takes 1.5-2 hours including clean up. Anyone can learn to solder in less than 30 minutes of practice.
Some softeners leave minimal water in the brine tank and add the water for this regeneration as the first cycle of this regeneration (pre fill) and others add it as the last cycle of this regeneration (post fill); they have the most water left in the brine tank.
Anytime you taste salty water, the most frequent cause is something using water during a regeneration, but there could be inadequate rinse also or... too much water in the brine tank and slow rinse was incapable of getting rid of all of it.
The added sodium a softener adds t othe water is 7.875 mg/l, roughly a quart, per grain per gallon of ion exchange (compensated hardness). Usually that's less than you get in a glass of skim milk; which is said to be 530 mg.
