How to Fix Backdrafting Water Heater

Backdrafting is a common problem that occurs when the exhaust gases from a water heater are not properly vented outside. This can lead to a buildup of carbon monoxide and other harmful gases in your home, which can be dangerous for you and your family. In this article, we will discuss how to fix backdrafting water heater and keep your home safe.

What Causes Backdrafting?

Backdrafting occurs when the pressure inside the home is greater than the pressure outside. This can happen for a number of reasons, including:

1. Poor Ventilation

If your home is not properly ventilated, it can create a negative pressure inside the home, which can cause backdrafting. This can be caused by a variety of factors, including a lack of windows, poor insulation, or a poorly designed HVAC system.

2. Blocked Vent

If the vent for your water heater is blocked, it can cause backdrafting. This can be caused by a variety of factors, including debris, bird nests, or other obstructions.

3. Improper Installation

If your water heater was not installed properly, it can cause backdrafting. This can be caused by a variety of factors, including improper venting, incorrect sizing, or a lack of proper ventilation.

How to Fix Backdrafting Water Heater

If you suspect that your water heater is backdrafting, it is important to take action immediately. Here are some steps you can take to fix backdrafting water heater:

1. Check the Vent

The first step in fixing backdrafting water heater is to check the vent. Make sure that it is not blocked by debris, bird nests, or other obstructions. If it is, remove the obstruction and clean the vent thoroughly.

2. Check the Draft Hood

The draft hood is the metal cap that sits on top of the water heater. It is designed to help regulate the flow of air and exhaust gases. If the draft hood is damaged or not installed properly, it can cause backdrafting. Check the draft hood to make sure it is in good condition and installed properly.

3. Check the Flue Pipe

The flue pipe is the pipe that carries the exhaust gases from the water heater to the outside. If the flue pipe is damaged or not installed properly, it can cause backdrafting. Check the flue pipe to make sure it is in good condition and installed properly.

4. Check the Combustion Air Supply

The combustion air supply is the air that is used to fuel the combustion process in the water heater. If there is not enough combustion air, it can cause backdrafting. Check the combustion air supply to make sure it is in good condition and providing enough air.

5. Install a Draft Hood Damper

A draft hood damper is a device that is installed on the draft hood to help regulate the flow of air and exhaust gases. It can help prevent backdrafting by ensuring that the pressure inside the home is not greater than the pressure outside. If you do not have a draft hood damper, consider installing one.
