When warm air passes over an air conditioner's evaporator coils, it is cooled. This usually reduces the moisture-carrying capacity of the air, triggering condensation. This moisture doesn't have a role to play in the air conditioning process and has to be drained off. This is done through a condensate drainage system that is made up of a condensate collection tray and a system of small pipes.
Mistakes in the installation of this drainage system can interfere with the draining process. This may then not only cause property damage, but also lead to bad odors in a home. The following are common condensate drainage system mistakes that you should look out for.
Most air conditioning systems depend on gravity when emptying the condensate collection tray. Therefore, if the condensate drain lines in your air conditioner are sloping up-hill, the drainage process will be inefficient. The water will find it hard to flow through the lines at places with an up-hill slope, something that will then increase the risk of the collection tray overflowing.
Up-hill slopes also increase the risks of blockages. This is because the rate at which the condensate flows usually reduces at up-hill sloped sections. This reduced pace then gives time for any dust particles that may have been washed down from the evaporator coils to settle. With time, this accumulation may end up blocking the drain lines. This may expose your home to moisture damage and mold growth that usually results from air conditioner water leaks.
To be on the safe side, make sure that the entire condensate drain line is sloped downwards. This will allow the condensate drainage system to take maximum advantage of gravity and thus reduce the risks of air conditioner leaks.
Direct connection to the house drain piping
When air conditioner drain lines are connected directly to a home's main drain piping, they usually expose the system to both bacterial hazards and sewer gas infiltration. This is because any bacteria in the drain piping can grow back up. With direct connections, there is also nothing that can prevent the sewer smells from climbing up the condensate drain lines and into your air conditioning system. This exposes a home to both bad odors and increased risks of bacterial attacks.
Avoiding direct connections to your home's main drain piping is advisable. You should instead direct your air conditioner's condensate drain lines outside so that they can empty the water to either the ground or your gutter system. However, if you must use your home's drain piping, making sure that a moisture trap is installed is advisable.Visit websites like http://www.aabsoluteplumbing.com for more information.
