For those who live in newer townhomes, one side note on turning off the water supply while away. These buildings are usually equipped with sprinkler systems. Our neighbours have been away for a month and my wife has been keeping an eye on their place. The other day she wanted to water some plants but found the water was off. She asked me to come turn it on. I assumed they would have turned off the valve that is downstream from the sprinkler feed line, but I arrived to find the main valve (the one with the big red tag saying "DO NOT CLOSE THIS VALVE") was closed. I corrected it and sent them an email to let them know why. They were embarrassed and said they didn't notice the shutoff valve they should have used, which still doesn't explain why they thought it was no problem to deactivate their sprinklers.
