Identify the location of all the smoke detectors in your house and make a plan for the order in which we'll check their batteries. We want to make sure we don't accidentally forget to check one.
Remove old batteries from the smoke detector and insert new ones.
Test to see that the smoke detector is working properly. To do so, stand up to four feet away from the smoke detector and spray it for 3 seconds. If the smoke detector alarm sounds your smoke detector is working properly. If your smoke detector has a test feature, use that to check if it is working properly!
Change batteries again after 6 months or if smoke detector starts to beep or chirp.How to Test your Sump Pump
