I hired a plumber 7 years ago to replace a section of corroded thru copper in the basement of our previous place and he used these new crimp on fittings with an O-ring inside and a machine to crimp it. Seems the new generation of plumbers aren't doing the old solder either. I asked how long the o-rings were going to last and he said the method was too new to know..... oh well, not my problem.
I do have several of the slip on fittings in this house now for water heater and softener and do look for telltale signs of any seepage occasionally.
Garage doors... I replaced the original on our current home 4 years ago and last winter the damn thing froze down overnight and when I hit the open button, the top panel folded in before the ice let go. I bought a 16' piece of 1/8th inch 2x2 aluminum angle and put that on top to reinforce it but the panel really needs to be replaced, as it doesn't seal well at the top. Something that is on the "someday" list, but should be looked at ordering a new panel now before winter.
I was shocked when I bought the angle piece, as that alone was $100 !!! I will install that on the new panel right from the git-go and hope this doesn't happen again. The door faces north and when we get a north wind with freezing rain, MAYBE we will stop to think about the door being frozen down next time.....naw, we'll never remember...
