The leakage of water from your swamp cooler could be attributed to a variety of reasons. One common cause is an overfilled water tank, which occurs when the float valve is maladjusted or malfunctioning and does not shut off the water supply when the tank is full.
Another potential issue might be a leaking cooler pad. If the pad becomes too saturated with water, it could leak.
A damaged or cracked water reservoir might also be the culprit, as it could cause water to seep out. It’s essential to diagnose the exact cause of the leakage to apply the most effective solution.
Swamp Cooler
The cost-effective alternative to traditional air conditioning systems is a swamp cooler, an evaporative cooler. It operates based on the principle of evaporative cooling, where it uses water to reduce the surrounding temperature.
In a swamp cooler, a pump circulates water from the reservoir onto a cooling pad, making it wet. A fan then draws air from outside the unit through the moistened pad. As the air passes through the pad, it is cooled by evaporation.
Swamp coolers use significantly less electricity than standard air conditioners, so their energy efficiency is a critical benefit. Additionally, they perform best in hot and dry climates and serve to increase the humidity in arid areas, making the environment more comfortable.
How to Fix a Swamp Cooler That Is Leaking Water: 7 Steps
Turn Off the Power
Before you begin any maintenance or repairs on your swamp cooler, the first and most crucial step is to turn off the power. This is a critical safety measure to protect you from electrical shock.
Locate the primary power source of your swamp cooler, which is typically a switch or circuit breaker. Make sure to turn it off completely.
If you’re unsure about this step or uncomfortable dealing with electricity, call in a professional to ensure safety. Remember, safety should always be your top priority when dealing with appliances.
Check the Water Supply
After ensuring the power is off, the next step is to inspect your swamp cooler’s water supply. Start by examining the water line running to your cooler. Look for any signs of leaks or damage that could be causing water to escape.
In particular, check the condition of the water hose and fittings that connect to the float valve. If these parts appear in good condition, the problem might lie with the float valve, which controls the water level in the cooler.
If the valve is malfunctioning or incorrectly adjusted, it may allow too much water into the unit, causing an overflow and subsequent leakage.
If you notice any problems during this examination, or if your work seems too complex, repair or replace the damaged parts and call a professional.
Inspect Your Reservoir
While inspecting your swamp cooler’s reservoir, it is essential to understand that it is the component that holds the coolant – water. This reservoir can be potentially susceptible to wear and tear over time. Cracks, holes, or other forms of damage might form, resulting in unwanted water leaks.
To inspect the reservoir, you must empty, clean, and dry it thoroughly. The next step involves refilling it with a limited amount of water. During this process, observe any signs of water leakage, such as seeping, dribbling, or dripping.
If you spot any water escaping, the reservoir is likely damaged. Depending on the severity of the damage, you may apply a waterproof sealant for minor cracks, while a complete reservoir replacement may be required for larger ones.
Replace the Reservoir Liner
If your inspection reveals that the reservoir liner of your swamp cooler is damaged beyond repair, replacing it might be the most effective solution. The liner’s function is to hold the water within the cooler, so a damaged liner could be the primary cause of leakage.
First, procure a new liner that matches the size and model of your swamp cooler to replace the reservoir liner. Carefully remove the old liner and clean the reservoir thoroughly to remove any buildup or debris.
Once cleaned, install the new liner according to the cooler’s manual. Ensure it fits snugly without any gaps or bends. Replacing the reservoir liner can be a straightforward process.
Still, if you are unsure, it may be best to hire a professional to avoid any installation issues that could lead to further leakage.
Check Your Drain Plug
The drain plug is another critical component to inspect when troubleshooting a leaking swamp cooler. Usually, the drain plug is located at the bottom of the cooler’s reservoir.
The primary purpose is to be removed when you want to drain the water entirely from the cooler, such as at the end of the cooling season or when cleaning the unit.
If the drain plug is not secured correctly or damaged or worn out, it can cause a slow but consistent leak. If there are any signs of damage, check the drain plug and make sure it’s secured tightly.
If you find the drain plug to be the source of the leak, it’s generally simple and inexpensive to replace.
Check the Float Switch
The float switch is a crucial element of your swamp cooler as it regulates the water level in the reservoir. It functions similarly to the float mechanism in a toilet tank. When the water level in the cooler’s reservoir drops, the float switch activates the water supply.
Conversely, the float switch turns off the water supply when the reservoir is complete. If your swamp cooler leaks, the float switch may malfunction, be stuck, or improperly adjusted, causing the reservoir to overfill and water to leak.
To inspect the float switch, check if it’s moving freely and turn the water supply on and off at appropriate water levels. It may need to be adjusted or replaced if it is not functioning correctly.
Inspect the Water Pump and Distributor Lines
The water pump and distributor line are crucial in your swamp cooler’s operation. The pump propels water from the reservoir to the cooler’s pads through the distributor lines. If the pump is faulty or the lines are blocked or cracked, water may not reach the pads and could leak from the cooler.
Begin your inspection by checking the water pump for any signs of damage or malfunction. Run the cooler and observe if the pump is pushing water effectively. Next, examine the distributor lines. These should be clear of any blockages and free from cracks or holes.
It may need to be repaired or replaced if the pump is malfunctioning. Similarly, if the distributor lines are damaged or blocked, they must be cleaned or substituted with new ones to prevent leakage and ensure the efficient operation of your swamp cooler.
Risks of a broken swamp cooler
A broken or malfunctioning swamp cooler presents several risks that can impact the comfort of your space and your health and safety. One of the main concerns is mould and bacteria growth in the cooler’s reservoir due to irregular cleaning or accumulation of standing water.
This can pose a severe health risk, causing respiratory issues or allergies. In addition, a leaky g swamp cooler can lead to water damage in your home, damaging floors, walls, or furniture and potentially leading to costly repairs.
Furthermore, if water comes into contact with electrical outlets or wires, it can pose a severe electrical shock or fire risk. Lastly, a faulty swamp cooler will not effectively cool your space, leading to discomfort, particularly in extreme heat.
Final Thoughts
A leaking swamp cooler can result from various issues ranging from a malfunctioning float valve, damaged r reservoir, compromised reservoir liner, defective drain plug, faulty float switch, or problems with the water pump and distributor lines.
Water leakage can be prevented, and the cooler’s lifespan can be increased by regular inspections and maintenance of these components. While you can perform some of these repairs, complex issues may require professional assistance.
Therefore, understanding the root cause of the leakage can guide you to the appropriate solution, whether a simple replacement part or a call to a skilled technician.
By routinely addressing these potential issues, you can ensure your swamp cooler operates efficiently, providing excellent relief during hot weather.
