They really do, and so many people have zero clue what to do. I think I have told this story before....but anyhoo.
Story time.
I have a buddy, smart guy not smart about anything around the home. In casual talking over lunch he said he had to have a plumber out the other day, cost X. Really what went wrong, something that was suppose to go down came back up? Nope the toilet would not stop running. Ahh nothing else, nope was costing money. That is such an easy fix.....for you it is. No it is really easy for anyone, go on youtube and look up three videos, they will all say about the same thing, just do that and if you get stuck holler at me.
I am building a loft for my shop, as well as finally running power to my barn, so lots of nails and screws as well as some copper.....good god wire is expensive.... Told him if he wants to come out and "help" he is welcome, might learn a thing or two.....he wants to.....provided there is not a Chiefs game on. Guess what is important to you, whatever.
I talked on another thread about setting up a solar/wind power setup. Building it all myself, well buying the solar cells, the turbine I already had from when I was racing, used it on the back of the motorhome to charge the batteries....always windy at race tracks, worked well and I was easy to find, look for the RV with the windmill sticking up.
So the batteries, charge controllers, wire, building the mounts for the solar cells, doing all of that, and I am having fun and learning stuff along the way.
Point is another guy asked me how do you know all this stuff, never really thought about it before, I really don't know. I guess it is all the little things I learned on the blue marble. I was always one to take stuff apart.
