Gas Furnace Water Drain

This adds up to a lot of water vapor.

Gas furnace water drain.

Fix the problem with chemical tablets and a larger drain hose. Most furnaces will have at least 2 internal drains typically one for the heat exchanger and one for. These allow the furnace to extract heat from the gases for a longer period of time. Additionally the inducer motor would suck air through the drain if it weren t trapped which could.

Problems with the condensate pump. If the furnace is producing condensation during the winter the problem could be that one of these pipes has frozen and is backing up all the way to the main furnace unit. These pipes run throughout your house and certain pipes even run outside. High efficiency furnaces naturally produce condensation as a by product of the natural gas burning.

After the water stops flowing turn off the boiler drain and disconnect the garden hose. Check to see if the expansion tank a small barrel shaped tank located near the boiler has a drain on it. Unlike conventional water heating systems closed hot water boilers should only be flushed when operation problems occur. The condensation is then draining onto or around the area of your house where the furnace is.

However if this tube becomes clogged or if the drain on your floor becomes it can cause water to backup and leak out of. This is typically flown out of a pvc pipe that comes from the furnace and drains into the floor drain in your furnace room. The condensate trap is absolutely mandatory for a high efficiency gas furnace. A condensate pump is a small white box.

This causes the combustion gases to cool and then condense. But if that water is pooling around the furnace there s a. If you notice water around the furnace the condensate drain may be clogged with slime. Shove the tablets into the drain pan opening and push them in farther using a dowel or long screwdriver.

Add new tablets monthly during air. Since the drain taps into the exhaust system leaving it open to the air would allow for a potential exhaust flue gas leak in the living space which is a big no no. Remember to give the system time to drain and fill. Some high efficiency furnaces may use a condensate pump to push condensation toward the proper draining area.

But a high efficiency furnace to extract more heat has 2 heat exchangers. That condensation then exits out your home through a drain.
