One of the common handyman repairs and installations discovered during a home inspection Hamilton or home inspections Waterdown is the dishwasher hookup. The home inspector explains to the client why the present installation is wrong and the proper way to install a dishwasher drain hose. The above picture was from a Hamilton home inspection or a Waterdown home inspection, the drain hose is connected to the plumbing drain line after the trap. The home inspector points out to the client that there is the potential of sewer gases to enter the dishwasher posing a health risk. The drain line for the dishwasher should be connected to the drain line before the trap, thereby, not allowing sewer gases to enter the dishwasher. The second observation has the drain line with a high loop which is a good installation, many dishwasher hookups do not have a high loop and therefore backups from the drain line could enter the dishwasher.
