What is Backdrafting?
You don’t want your water heater sucking, physically or metaphorically. But that is essentially what is happening when your water heater is backdrafting due to a flaw in the installation or an obstruction in your piping.
Check for Backdraft
Now if you are here, you probably have already diagnosed the issue. But if you want to double check – here is a quick trick. Grab a mirror and locate your draft diverter (at the top of your water heater near the hood). Carefully hold the mirror to it and if your water heater is indeed backdrafting, the mirror will become foggy. Other tell-tale signs include the presence of soot, corrosion or distortion of the metal, plastic,or foam on your appliance.
Now, The Important Part.
Backdrafting can be dangerous. You’ll want to fix it as soon as you determine the issue and unfortunately a DIY won’t cut it. Generally the cause of backdrafting is a botched vent installation or a buildup or obstruction within your vent pipe.
If you want to avoid this problem in the future, stay away from atmospheric vent water heaters which are affected most by this malfunction.
