Any water leak is a significant concern, especially since it can lead to household disasters, health issues, and even allow mold to grow. Any conventional furnace, better known as a standard-efficiency furnace, does not produce water.

There are several reasons why these leakages may happen in your conventional furnace. You should be wise enough to keep regularly checking to take care at the very outset to avoid any long-term damage or unnecessary health implications. However, if any damage occurs, call furnace repair professionals to help solve the issue.

Why Should You Keep Checking?

All high-efficiency furnaces create condensation, mainly because of this second heat exchanger installed in it. The secondary heat exchanger takes the exhaust, or the flue gas, from the primary heat exchanger to further heat the exchange. This is where water vapor is formed. Due to the condensation, the water is drained by a condensate pump to a floor drain.

So, let us look at the most common reasons why your furnace is leaking water:

Leakage in the Inducer assembly

The condensation runs down an exhaust or flue pipe through a condensate drain hose into an inducer assembly. If the inducer assembly itself has a crack in it, water will leak out of the furnace. Such a leak should be taken care of at a very early stage to resist further damage.

Leakage in the Condensate drain hose

A drain hose slopes downward from the PVC exhaust pipe that can easily be clogged with dust, dirt, and debris. Naturally, if any tube that helps in the draining is damaged, blocked, or disconnected, the condensed water can very well leak. Constant monitoring and regular checkup are essential to avoid such a problem.

Leakage in the Condensate trap

If your condenser trap is clogged or blocked in any way, it can cause the condenser to back up and overflow out of the furnace. However, please also note that not all high-efficiency furnaces have a condensate trap.

Leakage in the Condensate drain line

The water exists and passes through a condenser drain line. If there are cracks or holes in it, or the connection itself is loose at some point, water will leak out of it. Please note that a clog in this condenser drain line can also cause the condensate to back up and create an overflow or leakage.

Leakage in the Condensate pump

The condensate finally drains into the condensate pump. Any club or blockage can create leakages. Please remember that any leakage of any sort can not only be the cause of a disaster, but it can also lead to health issues and even damage your property itself. And if such problems are not taken care of well in advance, you may have to bear costly repair and rectification later on.

Verdict

Now that you know why your furnace is leaking water, you must ask for professional help to come and check your furnace and ensure that any leakage is taken care of appropriately, whether by simply repairing the wrong spot or even replacing a component or a part of your furnace.
