Test the Sump Pump or Risk a Flood
To avoid a similar disaster, be sure your pump has a vertical float switch. Also, check your pump at least a couple times a year by dumping water into the basin to make sure everything is working properly.
Clean Dryer Vents or Waste Energy and Risk a Fire
You'll have to remove the vent from the back of the dryer to clean it. Suck debris from the ducts with a wet/dry vac, or ream them out with a cleaning kit that includes a brush on a long flexible rod that attaches to a power drill. The kits are available at home centers. If your ducts need replacing, get smooth metal ducts, which will stay cleaner longer than the rough corrugated surface of flexible ducts. Avoid plastic ducting altogether; it can be a fire hazard. Plus: Slash Heating Bills
