What You'll Learn
Cracked water tank
If you're experiencing a water leak in your camper, it's important to address the issue as soon as possible to prevent further damage. A cracked water tank is one of the possible causes of water leaks underneath your camper, and here's what you need to know about it:
Identifying a Cracked Water Tank:
- Check the external seals and gaskets first, as these are common entry points for water leaks.
- Turn off all faucets, disconnect the hose from the freshwater tank, and check the ground around the camper for signs of water.
- If you suspect a leak in the water tank, ensure it's completely full, then disconnect the hose and check for moisture on the ground as the water drains out.
Temporary Solutions:
- If you have a minor leak, you can try sealing it with caulk or tape as a temporary solution.
- For larger leaks, you may need to apply a more generous amount of sealant and use tape to secure it.
- Tighten any loose screws or fittings with a screwdriver and pliers.
Permanent Solutions:
- For a more permanent solution, you may need to replace the entire water tank, especially if it has suffered a serious rupture.
- Make sure to consult the manufacturer's instructions for the installation procedure.
- Depending on the make and model of your camper, you will need to find a suitable replacement tank.
Preventative Measures:
- Regularly inspect your water tank for any signs of damage or wear and tear.
- Ensure proper maintenance by keeping your water tank clean and refilled, and empty your holding tanks frequently.
- Always use clean water when filling your tanks to avoid any buildup.
Remember, water leaks in your camper can lead to serious issues, so it's important to act quickly and seek professional help if needed.

Broken hose
A breach in the water system is the most common cause of water leaks in campers, RVs, and travel trailers. Hoses are often one of the main culprits behind water leaks. A hose could have been punctured, ruptured, or it may have just come loose.
If you suspect that a broken hose is causing a water leak in your camper, the first thing to do is turn off all water coming into the vehicle and close all faucets. Next, drain all water from the vehicle and perform a pressure test using an air compressor. The escaping air will create a hissing sound, which will help you pinpoint the leak so you can fix it.
If you are unable to locate the leak, try adding some water back into the system and repeat the pressure test. If the leak is still not found, remove the underbelly cover from your camper to get a better idea of the source.
Once you have located the leak, you can fix it by buying replacement parts or using patching materials. If the leak is large and the hose cannot be properly patched, you will need to replace it with a new one.
To prevent water leaks in your camper, it is important to regularly inspect your vehicle for any signs of damage and perform maintenance as needed.

Broken valve seal
If you have a water leak in your camper, you need to address the issue as soon as possible. A water leak can cause serious issues and potentially result in irreversible damage.
A broken valve seal is one of the most common reasons for water leaks in campers. The water pump in your RV has a special valve seal to keep it closed when not in use. Over time, these valve seals can get old and break. If this is the issue, you might also experience trouble pumping water.
To fix a broken valve seal, you will need to buy a replacement seal and install it. Here are the steps you can follow to locate and fix the leak:
- Turn off all water coming into the vehicle and close all faucets.
- Drain all water from the vehicle.
- Perform a pressure test using an air compressor. Attach an air compressor (with a pressure gauge) to the city water inlet valve and inject air into the system at 80-100 PSI.
- Wait for about 10 minutes. If the pressure has dropped, you have a leak.
- Listen for a hissing sound. This is where the air is coming out, and also where the water will be leaking out.
- If you don't hear any hissing, go outside and examine the underbelly of your camper. Unscrew the rubber underbelly from the camper frame and remove it.
- Discard any water-clogged insulation material.
- Using a flashlight, examine each component and hose for signs of water leakage from the fresh, grey, and black water holding tanks.
- Pressurize the system again by attaching the compressor to the water pump inlet valve.
- Listen for a hissing sound and look for a misty spray of water.
- If no leak is detected, fill the system with water and allow the water pressure to expose the leak.
- Fix the leak with the appropriate parts and products.
- Fit new insulation to the underbelly.
- Refit the underbelly.
- Return water to the RV and test the city water system and the freshwater tank system.
By following these steps, you should be able to locate and fix a leak caused by a broken valve seal in your camper.

Clogged drains or vents
If you have recently filled your tank with water, you may have overfilled it, which can cause a leak. Similarly, if you haven't emptied your grey and black water tanks in a while, they may be overfilled and leaking.
If you suspect a clogged drain or vent, you can use a plumber's snake or a specialised RV vent cleaning tool to try and clear the blockage. If the clog is stubborn, call in a professional to address the issue without causing further damage.
To identify a clog, you can perform a water pressure test. Drain the water from the system, close all the faucets, and empty the toilet. Attach an air compressor (with a pressure gauge) to the city water inlet valve and inject air into the system at 80-100PSI. Wait for ten minutes and if the pressure has dropped, you have a leak. Listen for a hissing sound to help you locate it.
If you are unable to locate the leak, try adding some water back into the system and repeating the pressure test. If you still can't find it, remove the underbelly cover from your camper to get a better idea of the source.

Water heater issues
Water heaters are a common source of leaks in campers, and there are several reasons why this might be happening. Firstly, it's important to note that water heaters need to be maintained regularly to ensure optimal performance and longevity. Even with routine maintenance, however, leaks can still occur due to various issues.
One possible cause of a leaking water heater is a faulty pressure relief valve. The pressure relief valve is a safety mechanism that releases pressure when it exceeds a certain level. If your water heater is leaking from this valve, it may be doing its job, especially if it only leaks when the tank is hot. In this case, the solution may be as simple as refilling the tank to the correct level and ensuring there is an adequate air gap. If the valve is leaking when the tank is cold or producing more than a drip, it may need to be replaced.
Another potential issue is a damaged drain plug. Drain plugs are typically made of plastic and are constantly removed and reinstalled for maintenance, making them susceptible to wear and damage. If the drain plug has a pinhole, it can cause a leak that becomes pressurized and turns into a spray when the tank is heated. Replacing the drain plug is usually a straightforward fix.
Leaking can also occur from the water inlet or outlet, which may be due to loose connections. Tightening the nuts or valves can often solve this issue, but if the leak persists, the inlet or outlet may need to be replaced.
In some cases, the leak may be coming from the heater element gasket, which is often covered and hidden. If this is the source of the leak, it will need to be replaced by a qualified technician.
Finally, plumbing or water lines can also be the culprit. Exposure to extreme weather, particularly freezing temperatures, can cause these lines to freeze, thaw, and develop cuts or splits, resulting in leaks. Patching the cuts or removing and reconnecting the affected sections of the water lines may resolve this issue.
It's important to address a leaking water heater as soon as possible to prevent further damage and potential safety hazards. While some of these issues can be simple DIY fixes, it's always best to consult a professional contractor or technician to ensure proper diagnosis and repair.
