I grew up with soft water and have never really liked the taste of hard water. Our new place had some plumbing for a water softener but no softener. So today we got one and I installed it. The flexible connection pipes were way to big, but I found a way to "ram" them in there...
The skills I learned working for the church sweating copper air pipe came in handy. Though I used way too much solder it still looks and works OK. I left my torch in New Hampshire since I couldn't transport the flammable tank, so I borrowed my dad equipment to do this job. I would have purchased my own but in a finished house I can't ever see needing it again.
