Why Is My Furnace Leaking Water? How To Fix It [With Pictures]

Damage caused by water is a typical issue that many homeowners have to deal with. A water leak may be a serious problem, and it can even

cause mold to develop if it’s left unchecked. This has the potential to lower the quality of the air within and possibly lead to illnesses. A water

leak from the furnace is a problem that many homeowners dread having to deal with. However, there is no need to freak out since the source

of the leak might be something quite minor and simple to repair. Troubleshooting may help cure small difficulties, but if the problem is more significant, you should call an expert in heating, ventilation, and air conditioning to do any required furnace repairs.

It is in everyone’s best interest to deal with the issue before it causes significant damage that will need expensive repairs at a later date. The purpose of this article is to give information on what steps may be taken in the event that water is leaking from a furnace; however, before

getting into that, it is important to understand why furnaces leak water and the risks that are involved with it.

Most Common Problems That May Be Causing Your Furnace to Leak Water

Determine the sort of furnace you have so you can get closer to finding out what caused the leak. When glancing at the exhaust pipe, one

can very easily determine the sort of furnace that is being used. A standard-efficient furnace has a metal furnace and does not create

condensation; in contrast, a high-efficiency condensing furnace has a white plastic PVC exhaust pipe. A standard-efficient furnace does

not produce condensation.

What factors contribute to a high-efficiency furnace’s tendency to drip water?

Because high-efficiency furnaces produce condensation as a natural byproduct of their functioning, the water leakage is very certainly going

to need some minor furnace repair. The following are the most typical causes:

  • The Condensate Drain Pipe

Condensation is produced by a high-efficiency furnace on a regular basis, and it is removed from the system via a condensate line or drain

hose. When this happens, the drain line might get blocked, which leads to leaks around the base of the furnace. The harm caused by water

may begin as soon as the water begins to pool.

  • Condensate Pump Spilling Its Contents

Another component in the system that may get clogged and cause leaks is the condensate pump. It is possible for a furnace to spring a water

leak if the condensate drain that leads to the condensate pump becomes clogged. It is a sign that the condensate is not draining properly if

you see water on the floor near the furnace unit or rust spots within the cabinet. A faulty pump may also cause water to flow backward, which

can lead to a leak in the system.

  • Issues with the Inducer Assembly

Through the condensate drain pipe, the condensate is directed to flow down the exhaust and into the inducer assembly. When the inducer

assembly in the furnace develops a fracture, water will begin to seep out of the device. What if it’s an old-fashioned furnace that doesn’t

heat very efficiently? What may have caused the water to flow from the pipe? Here are

some things that you should keep an eye out for:

  • A Problem with the Humidifier Spilling Water

The presence of a puddle of water next to the furnace may be attributable to a leaking built-in humidifier, in the event that such ahumidifier

is included in the furnace. In order for humidity to be produced, humidifiers often need water, and as a result, water will flow through the

humidifier and eventually drain out. It is possible for water to leak from the humidifier if the water lines become broken, cracked, or

blocked for any reason.

  • Broken Drain

Drain pans are often positioned underneath the evaporator coil in air conditioners. There are some that feature an additional drain pan

located underneath the unit. The drain pan’s function is to collect condensate; however, if the pan is damaged in any way, the condensate

and any extra water will be lost. If the water escapes from the furnace while the air conditioner is running, the issue may not be the furnace

but rather the air conditioning unit.

  • Pipe with Poorly Conceived Ventilation

The gases that are created as a byproduct of the combustion process are carried safely outside of the house via the flue pipe in a traditional

furnace. When the exhaust pipe does not have a slope or when it is too large, it permits an excessive amount of air to flow, which results in

gases being trapped within the flue. When these gases are allowed to remain in the flue for an extended period of time, they begin to cool and

condense, which then causes them to escape the furnace into the surrounding environs.

How Dangerous Is It When a Furnace Has Water Leaking into It?

Even though a leaky furnace does not immediately endanger the homeowners’ safety, it might reduce the level of comfort they experience

in their house. If the issue with the leaky pipe is not addressed, it may grow more expensive to fix.

Rust may form inside of a furnace if there is a leak, which can eventually ruin the portions of the furnace that are used for functioning. In the

long run, it will make things less efficient, which will result in breakdowns and expensive repairs. Rust that creates a fracture or a hole on the

heat exchanger, which causes exposure to dangerous gases, is far worse than the previous scenario. The inhalation of poisonous gases may

have significant implications for the general health of householders.

In addition to wreaking havoc on the heat exchange, water seeping out of the furnace may wreak havoc on the various electrical components.

This might cause damage to the furnace, which would result in it being completely inoperable. For example, a circuit board is responsible for transmitting the necessary signals for the heater to begin operating. In the event that water makes its way into the circuit board, you will be

forced to replace it as soon as you can. Before the situation becomes any worse, it is important to get in touch with a skilled HVAC service

specialist for emergency furnace repair.

What to Do in the Event That Your Furnace Is Leaking Water?

Leaks may be harmful, and if they are allowed to continue without being handled, they can cause damage to the flooring, furnace components,

clean, you can use napkins or towels, but if there is an excessive amount of water, you may want to consider using a wet-dry vacuum.

  1. Remove any water from the inside of the heating appliance.

Don’t get worked up. The removal of the water from the inside of the heating appliance is neither difficult nor hazardous. Unscrew the panel

on the front of the furnace, and wipe out any water that may be within. However, if you are experiencing any kind of discomfort, you should

contact emergency furnace repair services.
