Not only does this reduce the flow of water down the drain, it also means the food will start to breakdown and a build-up of bacteria can form in the pipes. During the summer the heat often increases the rate in which this happens intensifying the unpleasant odours and making them much more noticeable.
The smell is usually created when dust settles on the heat exchanger after a long period of heater inactivity. So when the heater is turned on, the dust gets burned off. It's normal for this to happen. But if the burning smell doesn't go away after a while, you should call us immediately!
In case you notice the smell of sewage water emanating from the vents, it may be that an open sewer line or a broken wastewater line may be located near the system. A quick inspection of the external vents can help identify the source of the smell. You may have to call a plumber to resolve the issue.
If you detect a sulfuric, rotten egg-like smell coming from your furnace, it is imperative that you act immediately, as you could be dealing with a gas leak.
