Gas Furnace Water Drain

These pipes run throughout your house and certain pipes even run outside.

Gas furnace water drain.

If you notice water around the furnace the condensate drain may be clogged with slime. But a high efficiency furnace to extract more heat has 2 heat exchangers. Problems with the condensate pump. The condensate trap is absolutely mandatory for a high efficiency gas furnace.

But if there is an issue or a clog anywhere in the condensate line or drain water will begin overflowing and leaking from the furnace and onto the floor. After the water stops flowing turn off the boiler drain and disconnect the garden hose. Some high efficiency furnaces may use a condensate pump to push condensation toward the proper draining area. Most furnaces will have at least 2 internal drains typically one for the heat exchanger and one for.

This is typically flown out of a pvc pipe that comes from the furnace and drains into the floor drain in your furnace room. A condensate pump is a small white box. In order for the furnace to work properly that condensation needs to be drained out or else it would accumulate inside the heat exchanger inducer and venting impeding proper gas combustion product flow. Unlike conventional water heating systems closed hot water boilers should only be flushed when operation problems occur.

But if that water is pooling around the furnace there s a. This adds up to a lot of water vapor. Check to see if the expansion tank a small barrel shaped tank located near the boiler has a drain on it. Whether you use radiators or radiant heating the process of draining and refilling the boiler is relatively simple.

Shove the tablets into the drain pan opening and push them in farther using a dowel or long screwdriver. High efficiency furnaces naturally produce condensation as a by product of the natural gas burning. That condensation then exits out your home through a drain. These allow the furnace to extract heat from the gases for a longer period of time.

This causes the combustion gases to cool and then condense. 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. The condensation is then draining onto or around the area of your house where the furnace is. Fix the problem with chemical tablets and a larger drain hose.

However if this tube becomes clogged or if the drain on your floor becomes it can cause water to backup and leak out of. 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.
