I had a stack able washer and dryer and the dryer broke, so we never got another one. I have a standard washing machine and we hang out clothes to dry (we only have 210/220 plugs and can't get a dryer). I use Gain or Wisk detergent and my clothes rarely smell good. Should I buy a smell enhancer for laundry?
As mentioned in other answers, 'Program Files', should NOT be used to save user files, however if you do need to save it in this location, you would need to Elevate UAC. You can do this: Let's say you want to save a word file to that directory, 1. Right click on MS Word's icon, and select 'Run as administrator' 2. Open/Create/Modify the file you want, now you can save it anywhere, since Word is running with an elevated privilege.
Shark branded brass fittings have worked nicely for me; they have a small C wrench that enables fast switch-out of the fitting, for pipe replacement, or fitting configuration changes and they fit CPVC as well as PEX (and K copper too I think?). Freezing is a problem no matter what material is used: all necessary prevention must be taken. Anything will be rendered useless if it gets frozen.
