Besides, engineers delight in optimizing systems. (I'm not a Greenie. But I see no reason to dump more salt into the earth than necessary.)
Ahhhhhhh...........this explains a lot! I tend to have an engineering mentality, but attribute most of my my issues to OCD, lol.
This site was a huge assistance when I DIY/weekend warriored/self-engineered the water softener in my home in 2017. I did a spreadsheet comparing the salt AND water use of numerous different configurations, but way short of ergonomicmike's tweaking.
I appreciate Master Plumber Mark's frankness and believe he may have called me out a time or two. It often brings the discussion down a notch or two, back to reality. Approaching old age (almost 69), I appreciate the experienced skilled trades people more than ever, and moan less about their exorbitant prices. I know that the licenses, insurance, government regulations, equipment, materials are a huge part of today's situation. It's too bad that getting trades work done today has gone this direction.
