Identifying Backdrafting Issues

There are a variety of ways to see if your water heater may be back drafting. First, look for damage around the tank such as melted seals or rust. Second, check for excess moisture on the tank, pipes, or walls where your water heater is located. Finally, check the pitch of your vent connector, which should pitch upward with at least a 1/4″ slope and avoid quick turns. Any or all of these problems likely indicate that your water heater has been improperly vented.

Why Do Water Heaters Backdraft?

These problems are often found in older houses where the water heater was improperly installed, has lost effectiveness over time, or was replaced with a newer water heater without adapting the venting system. When older furnaces are replaced with newer high-efficiency versions, the old system may not be able to properly vent and needs to be converted or adapted.

Options for Proper Venting

For many who are tired of dealing with backdrafting caused by atmospheric vents, which uses natural gravity to move the lighter unwanted gasses out the vent, a power-vented water heater may be the right alternative. These heaters use a fan to propel gasses out of the vent and are an efficient solution for homes with tight spaces or without a chimney. However, power-vented heaters are more expensive than traditional atmospheric systems, so customers should do their research to determine which type of water heater best suits the needs of their home.
