Getting water in your lawn mower’s gas tank is a frustrating and potentially costly problem that can happen to anyone. Whether it’s due to a faulty gas cap, a crack in the tank, or accidentally filling up with the wrong type of fuel, water in the gas tank can cause significant damage to your lawn mower’s engine. In this article, we’ll explore the consequences of water in the gas tank, how to diagnose the issue, and most importantly, what to do to fix it.
Understanding the Consequences of Water in the Gas Tank
Water in the gas tank can cause a range of problems, from minor issues to major engine damage. The extent of the damage depends on the amount of water present, the type of fuel used, and how long the water has been in the tank. Some of the common consequences include:
Water can cause the fuel to become stale and separate, leading to poor engine performance, reduced power, and decreased fuel efficiency.
It can also lead to the growth of bacteria and other microorganisms, which can clog fuel filters and injectors, causing further damage to the engine.
In severe cases, water in the gas tank can cause the engine to seize or fail, resulting in costly repairs or even requiring a new engine.
Diagnosing the Issue
If you suspect that there is water in your lawn mower’s gas tank, it’s essential to diagnose the issue as soon as possible. Here are some common signs to look out for:
The lawn mower may stall or struggle to start, indicating that the fuel is not being properly ignited.
The engine may run rough or produce a lot of smoke, suggesting that the fuel is not being burned efficiently.
You may notice water droplets or a slimy substance on the fuel cap or surrounds, indicating that water is present in the tank.
Using a Water Detection Kit
One of the most effective ways to diagnose water in the gas tank is to use a water detection kit. These kits usually consist of a test strip or a chemical solution that changes color in the presence of water. To use a water detection kit, follow the manufacturer’s instructions and take a sample of the fuel from the tank. If the test indicates the presence of water, it’s essential to take action as soon as possible to prevent further damage to the engine.
Draining and Cleaning the Gas Tank
If you’ve confirmed that there is water in your lawn mower’s gas tank, the next step is to drain and clean the tank. This process can be challenging, but it’s essential to remove all the water and contaminated fuel to prevent further damage to the engine. Here’s a step-by-step guide on how to drain and clean the gas tank:
First, make sure the lawn mower is on a level surface and the engine is cool.
Next, locate the gas tank drain plug and remove it using a wrench or socket.
Allow the fuel to drain completely, taking care not to spill any on the ground or surrounding surfaces.
Once the fuel has drained, use a clean, dry rag to wipe out the tank and remove any remaining water or debris.
Finally, add a fuel additive or drying agent to the tank to help absorb any remaining moisture and prevent further damage to the engine.
Drying the Fuel System
After draining and cleaning the gas tank, it’s essential to dry the fuel system to prevent any remaining water from causing further damage to the engine. One effective way to do this is to use a fuel dryer or desiccant specifically designed for lawn mowers. These products can help to absorb any remaining moisture in the fuel system, preventing corrosion and damage to the engine components.
Rebuilding or Replacing the Fuel System
In some cases, the damage caused by water in the gas tank may be so severe that the fuel system needs to be rebuilt or replaced. This can be a costly and time-consuming process, but it’s essential to ensure the lawn mower runs safely and efficiently. If you’re not comfortable with rebuilding or replacing the fuel system yourself, it’s recommended to consult a professional small engine mechanic who can assess the damage and provide the necessary repairs.
Preventing Water in the Gas Tank
Preventing water from getting into the gas tank in the first place is always the best option. Here are some tips to help prevent water from contaminating your lawn mower’s fuel system:
Always use a gas cap with a tight-fitting seal to prevent water from entering the tank.
Regularly inspect the fuel tank and surrounding areas for any signs of cracks, damage, or corrosion.
Avoid filling up the gas tank in the rain or in areas where water may be present.
Use a high-quality fuel filter to help prevent water and other contaminants from entering the fuel system.
Consider using a fuel additive or stabilizer to help absorb any moisture and prevent corrosion in the fuel system.
In conclusion, getting water in your lawn mower’s gas tank can be a frustrating and potentially costly problem, but it’s not the end of the world. By understanding the consequences of water in the gas tank, diagnosing the issue, and taking prompt action to drain and clean the tank, you can help prevent further damage to the engine and get your lawn mower running safely and efficiently again. Remember to always take preventative measures to avoid water from contaminating your fuel system in the future, and don’t hesitate to consult a professional if you’re unsure about any aspect of the process.
What happens if I accidentally put water in my lawn mower gas tank?
If you accidentally put water in your lawn mower gas tank, it can cause significant damage to the engine. Water and gasoline do not mix, and the presence of water in the tank can lead to a range of problems, including corrosion, rust, and engine failure. When water enters the gas tank, it can settle at the bottom and cause the fuel to become contaminated, which can lead to poor engine performance, decreased power, and increased emissions.
To prevent further damage, it is essential to take immediate action if you suspect that water has entered your lawn mower’s gas tank. You should stop using the mower and avoid starting the engine, as this can cause the water to circulate through the system and cause more extensive damage. Instead, you should drain the gas tank and clean it thoroughly to remove any water and contaminated fuel. It is also a good idea to consult a professional mechanic or small engine repair specialist for guidance on how to repair and maintain your lawn mower.
How do I drain the gas tank of my lawn mower if it contains water?
Draining the gas tank of your lawn mower if it contains water requires caution and attention to safety. You should start by disconnecting the spark plug wire to prevent the engine from starting accidentally. Next, you should locate the drain plug or fuel line and use a pair of pliers or a wrench to loosen it. Be prepared to catch any spilling fuel or water in a container, and avoid getting any fuel or water on your skin or in your eyes. You can also use a siphon hose or a fuel transfer pump to drain the tank, but be sure to follow the manufacturer’s instructions and take necessary safety precautions.
Once you have drained the tank, you should inspect it for any signs of corrosion or damage. If you find any damage, you may need to clean or replace the tank. You should also clean and dry the fuel lines, fuel filter, and carburetor to remove any water or contaminated fuel. After cleaning and drying the system, you can refill the tank with fresh gasoline and check the mower for any signs of damage or malfunction. It is also a good idea to consult a professional mechanic or small engine repair specialist if you are unsure about how to drain or repair your lawn mower’s gas tank.
What are the symptoms of water in a lawn mower gas tank?
The symptoms of water in a lawn mower gas tank can vary depending on the amount of water present and the type of engine.
