What to Do When Water Enters Your Generator?
Rain got cheeky and soaked your generator? First rule—do not switch it on. Pull the plug, dry it out safely, and check for signs of damage. Generators hate surprise baths, and acting fast can save you a fortune in repairs. Keep reading for the full game plan to bring your machine back to life.
What Happens if You Put Water in a Generator? Understanding the Damage
Generators and water? Never mates. One’s built to keep the lights on, the other wants to shut everything down. Mix them together, and you’ve got a recipe for disaster.
Water creeping into your generator can cause issues you won’t notice right away. Give it a day or two and suddenly, your trusty power source won’t even start.
Is It OK if a Generator Gets Wet? Assessing the Immediate and Long-Term Risks
It might look harmless—just a bit of water, right? Wrong. Even light exposure to moisture can cause lingering damage that’s hard to spot until it’s too late.
Whether it’s a splash from a hose or a full-blown downpour, water can get into places it shouldn’t. And once it’s inside? That’s when the real trouble starts.
Electrical System Damage and Short Circuits in a Wet Generator
Let’s be real—water and wiring have never gotten along. If water sneaks into the electrical system, it can short circuits, fry fuses, and cause total failure. Worst-case scenario? You cop a nasty shock.
Even worse, it could all happen silently—no sparks, no smoke—just a generator that no longer works when you need it.
Engine Hydro-Lock and Internal Corrosion from Water Ingress in Your Generator
Water in the engine is a different beast. If it makes its way into the cylinder, it could cause a hydro-lock. That means the piston can’t move, which could bend internal parts and wreck the motor.
Even if you dodge that bullet, moisture inside will still corrode metal parts over time. Rust is sneaky like that.
Prioritising Safety: Immediate Steps for Your Wet Generator
You might be tempted to crank the generator and see if it still runs. Don’t.
Start with safety first. The wrong move here can do more harm than good.
Shutting Down and Disconnecting a Water-Affected Generator
If your generator is on, switch it off immediately—but only if it’s safe. Do not touch it with wet hands or while standing in water. If it’s plugged into anything, disconnect it right away.
Use insulated gloves if needed. Your goal is to make the area and machine safe before anything else.
Preventing Further Damage After Water Enters Your Generator
Move the generator to dry ground or at least somewhere under cover. If you can, lift it up to help drain any trapped water underneath.
Open access panels and let some fresh air in. Don’t rush—give it time to breathe and dry.
How to Get Water Out of Generator: Step-by-Step Recovery Procedures
So your generator took a dive. Don’t panic. With the right steps, you might be able to bring it back without ringing a repair shop.
Initial Assessment and Drainage for Your Water-Damaged Generator
Start by giving your generator a good once-over. Check the fuel tank, oil chamber, air filter, and wiring for signs of water.
Get your tools ready—it’s time to drain and clean.
Draining Water from the Fuel Tank and Carburettor of Your Generator
If water made its way into the fuel tank, you’ll need to drain it all. Even a small bit of water can contaminate the fuel and stop the engine from running.
Also, empty the carburettor. A few drops in there can block fuel flow and cause stalling.
Removing Water from the Oil Sump and Air Filter Housing of Your Generator
Check the oil. If it looks milky or cloudy, water’s definitely in there. Drain the old oil completely and refill it once the engine is dry.
Then, pop off the air filter. If it’s soaked, replace it. A soggy filter just chokes the engine.
Thorough Drying Methods for Your Wet Generator's Components
Towels alone won’t cut it. You need a proper drying strategy.
Air Drying and Desiccants for Your Generator's Electrical Parts
Use clean cloths to remove any surface moisture. Then leave the generator in a warm, dry area with good airflow.
Chuck in a few silica gel packs or moisture absorbers near the control panel and outlets. They’ll help soak up what you can’t see.
Professional Drying Services for Complex Water Damage to Your Generator
If your generator was fully flooded or you spot signs of corrosion, call in a pro. Technicians have the tools to dry it without causing more issues.
They’ll also spot damage you might miss—and that could save your generator from a second disaster.
Restoring Your Generator: After Drying, Before Starting
It’s not ready yet. You need to do a couple more things before that first test run.
Lubricating Internal Components After Water Exposure for Your Generator
Once the internal parts are dry, add a bit of engine oil to the spark plug hole and cylinder. Crank the engine gently by hand to spread the oil and protect the surfaces.
This helps prevent rust and keeps everything moving smoothly.
Testing Electrical Continuity Before Attempting to Start Your Generator
Use a multimeter to check key circuits. If everything’s clear—no faults or breaks—you’re ready to give it a go.
Fill up with fresh oil and fuel, and only then, try to start the generator. Fingers crossed, it kicks back to life.
Preventing Water From Entering Your Generator: How to Cover Generator in Rain and More
The best fix? Not needing one in the first place. Let’s talk about stopping water from getting in at all.
Generator Cover and Generator Tent: Essential Protection for Your Outdoor Generator
Covers are your first line of defence. But not just any old tarp will do.
Selecting the Right Generator Cover for Your Specific Model
Pick a weather-resistant cover made for your generator’s make and size. It should fit snugly, keep rain out, and still let the air flow.
Avoid cheap, floppy covers—they won’t cut it in wild Aussie weather.
The Benefits of a Generator Tent for All-Weather Protection
Generator tents are purpose-built to handle rain, wind, and more. You can even run the generator while it’s inside one—just make sure the ventilation’s solid.
They’re a bit pricier but worth it for peace of mind.
How to Run Generator in Rain Safely: Addressing Operational Considerations
If you’ve got to run your generator while it’s raining, do it the safe way.
Understanding Safe Distances and Ventilation with a Generator Cover While Running
Never enclose the generator completely. It needs airflow to stay cool and to vent exhaust gases. Keep it one metre clear on all sides.
A breathable, water-resistant canopy can shield it without suffocating it.
Homemade Generator Cover While Running: DIY Solutions and Safety Cautions
You can rig a DIY cover using PVC pipes and heat-safe tarps—but it’s not without risk.
Make sure it’s stable, open, and allows full airflow. And don’t forget—no plastic near hot exhausts.
Strategic Placement: Minimising Risk of Water Ingress into Your Generator
Good location is half the battle.
Elevating Your Generator to Avoid Standing Water and Flooding
Use a pallet, concrete slab, or generator pad to keep it off the ground. That extra height helps prevent puddles from creeping in.
Even a few inches can make all the difference during a storm.
Choosing a Location Away from Runoff and Potential Water Sources for Your Generator
Place your generator somewhere high and dry. Avoid spots where water collects—like under gutters, near downpipes, or at the bottom of a slope.
If your backyard turns into a lake every wet season, you’ll want to pick the driest island.
Conclusion: Proactive Measures and Swift Action Safeguard Your Generator
Generators might be tough, but they’re not waterproof warriors. One rainy day can knock them out if you’re not careful.
Act fast when water gets in. Dry it properly. And most importantly—plan ahead to keep it safe from future drenchings.
A little prep now can save you a lot of stress (and cash) later.
