It's getting cold! You might want to winterize your home to prevent pipes/
faucets from freezing. Here are some tips:
1. The best way is to shut off the isolation valve to the outside hose bib
and then drain the hose bib;
2. Leave the faucets inside drip a little bit;
3. Leave the heating system running;
4. For a couple of bucks, you can buy outdoor faucet covers at Home Depot to
cover outside hose bibs. Here is the link: http://www.homedepot.com/p/Unbranded-Standard-Faucet-Cover-1950
