How do I stop my water heater from Backdrafting?
How do I stop my water heater from Backdrafting?
The simplest way to prevent backdrafting is to provide a source of replacement air (also called combustion air) for your furnace, water heater and fireplace to replace the air that flows up the chimney with the exhaust fumes (Fig. C).
What happens if a water heater is not vented properly?
The residual gas fumes from your water heater’s burn process must be drawn through the vent pipes and up the chimney to exhaust outdoors. When that isn’t happening properly, the results could be costly — or worse, extremely dangerous.
How do I know if my water heater is Backdrafting?
To check for proper draft, I simply cup my hands around the draft hood without actually touching it. If the water heater is backdrafting, I’ll feel warm, moist air coming out of the draft hood.
How can Backdrafting be prevented?
How to prevent backdrafting:
- A flue vent. A flue vent that is improperly sized (either too large or too small) or blocked by an animal nest will not draw the exhaust properly.
- Keep venting needs in mind.
- Know the ripple effects of changing mechanical systems.
- Open windows and doors.
What causes back drafting?
Most backdrafting is the result of the characteristics of this type of water heater. Combustion gases rise through the ventilation duct solely by the force of convection, which might not be strong enough to counter the pull from dips in indoor air pressure.
What causes air in your hot water line?
If you are having some air in hot water line without any other signs of corrosion, this can be caused by the reaction between the anode and your water. The anode rod create some hydrogen because of the water and this creates some bubbles in the air.

What is the proper way to vent a gas water heater?
The venting must be vertical or upward sloping so that the hot exhaust rises up through the venting to exit your home. Making sure that your home has a properly working vent system is imperative when installing a standard atmospheric vent with your water heater.
What is water heater back drafting?
Backdrafting is a dangerous situation where toxic combustion gases are not properly vented. Instead of rising up through a chimney and releasing outside, some exhaust gas enters the home. Backdrafting is primarily a concern with atmospheric venting gas water heaters.
How do you test for Backdrafting?
A quick check for backdrafting at the draft hood can be done with a match test. In a properly operating combustion appliance, the flame and smoke from a match held near the opening of the draft hood should be drawn into the hood. Remember that combustion appli ances may take up to one minute to establish a draft.
What creates a backdraft?
A backdraft is caused by the sudden introduction of air into a fire that has depleted most of the available oxygen in a room or building. When a fire has depleted most of its oxygen, the flames will die down, but the fuel will still burn in a smoldering state and still generate heat, like with charcoal.
What are the signs of backdraft?
Common signs of backdraft include a sudden inrush of air upon an opening into a compartment being created, lack of visible signs of flame (fire above its upper flammability limit), “pulsing” smoke plumes from openings and auto-ignition of hot gases at openings where they mix with oxygen in the surrounding air.
