Are your drains clogged? Use a common plunger to create a seal over your drain and attempt to push and blocks through the pipes. Be careful not to overuse corrosive drain cleaning chemicals, which could damage your pipes.
If your toilet won't flush properly, the first step is to use your plunger to push the blockage through the system. Do not flush the toilet multiple times or you may flood your bathroom.
If your handle isn't working, lift the cover of your toilet to make sure the chain is connected properly.
If your property loses power, ask your neighbors if you're the only home affected. Power outages sometimes occur during stormy weather or because of nearby construction. If you're the only home impacted, call the utility company for information.
If you don't have hot water, you need to check that your hot water heater is working properly. Check the thermostat and make sure the water temperature is at the right setting. You should also verify that the tank is not in vacation mode. Try to reset the tank and wait 15 to 20 minutes before testing the water temperature.
If your heater or air conditioner isn't working properly, check your thermostat to make sure the settings haven't been tampered with accidentally. Many modern thermostats allow you to reset the entire HVAC system with a few clicks.
You may also want to call your utility company to make sure there are no problems with your account.
