You know the drill. Something eventually stops working and you know you could have prevented the breakdown if you had only paid better attention. You can set yourself on a simple schedule to check a few items to help prevent a larger disaster.
Set a day, once a week, to walk down the hallway and check your smoke and carbon monoxide detectors. (if you have any gas appliances you'll really want one of those)
Now walk in your utility room and take a peek at the hot water heater. Is there any water dripping out of the faucet? Did you find a puddle on the floor? These small drips or puddles can become big trouble if you don't notice them early enough.
Don't forget each time you do laundry to clean out the lint trap. This will help your clothes dry faster, your drier will be more efficient and you will reduce the risk of fire.
