Plumbing cross connections and condensate connections

Why we should worry as Home Inspectors , safety!

The most common one I see other than the exterior hose bibb is with water softeners. As you can see from this example this is a direct connection between your drinking water and your sewer system.

What about AC condensate lines? What is the issue here? The issue here is that if the condensate connection is not proper you can contaminate the air handling system with sewer gases and potential harmful bacteria. We all remember legionnaire’s disease don’t we?  This was a contamination by the bacteria from a cooling tower that caused the outbreak.

Though it is not certain how much exposure to the bacteria is needed to cause disease, it has been shown that some people have developed infections after inhaling contaminated vapors for just a few minutes.

The legionella bacterium is different than most bacteria which are usually isolated to spreading within a small area. It has been possible that legionella bacteria may be capable of traveling as far as four miles through the air. The cases have nearly tripled over the past decade alone. We may need to think harder about cross connections as well as how hot we keep are water supply in our homes.

Proper evaluation of the potable water supply and any connections with potential contamination sources needs to be completed.
