Eliminating Sewer Gas Smell In Campers: A Quick Guide

If you own a camper, you may have experienced the unpleasant surprise of a sewer gas smell. This nasty odour can be off-putting and embarrassing, ruining the enjoyment of your outdoor adventure. Luckily, there are several ways to tackle this issue and ensure your camper remains a pleasant space. From checking for leaks and proper ventilation to using natural odour absorbers and maintaining your plumbing, this article will provide an in-depth guide to eliminating sewer gas smells and keeping your camper fresh and welcoming.

Locate the source of the odour

Locating the source of the odour is the first step in getting rid of the sewer smell from your camper. This may seem obvious, but there could be multiple odour sources in your camper, and they may not all be located in the same area.

Check Your Hoses for Leaks

Hoses that aren’t correctly connected can cause many problems with sewer smells. Ensure they’re securely attached to the tanks and that any clamps are tight enough to keep them from leaking. If there’s an odour coming from the toilet or shower, check those hoses.

Check Your Drains, Toilets, and Plumbing Fixtures

Check your drains, toilets, and plumbing fixtures for signs of leaking or damage. Look for cracks or loose connections, and inspect sewer vents outside the camper to identify the source of the smell.

Check Any Loose Connections

Loose connections along the vent pipe or sewer line can let pungent gases into your camper. These will most typically be inside a wall or in the ceiling, requiring the help of an experienced plumber to correct this issue.

Keep Water in All of the Traps

Plumbing traps can be found in the floor, wall, or under a sink or toilet. Figure out where they are and ensure the least-used traps keep their water level. For the seldom-used traps prone to drying out, pour a couple of tablespoons of vegetable oil on top of the water to help slow evaporation.

Check for Dry Water Traps

When water traps dry out from lack of use, sewer gas has a clear path into the camper. Water traps are commonly located near floor drains and laundry tubs and are underneath every sink in the camper. They work by trapping water inside the curve and blocking the gas from returning to the camper. If the smell comes from a sink, run the water for a few seconds to restore the trap. If the smell comes from a floor drain, pour a pitcher of water down the drain to restore the proper function.

Check for Blocked or Clogged Drains or Vents

Blocked or clogged drains or vents can cause a sewer gas smell by prohibiting proper ventilation and drainage of the plumbing system. Accumulated debris, such as food particles, grease, hair, or other foreign objects, can block drains or vents, causing gases to infiltrate the camper. Regular maintenance and cleaning of drains and vents can prevent blockages and keep the plumbing system functioning properly.

Check hoses for leaks

To get rid of sewer gas smells in your camper, it's important to check your hoses for leaks. Hoses that aren't correctly connected can cause many problems with sewer smells. To prevent this, it's crucial to ensure they are securely attached to the tanks and that any clamps are tight enough to keep them from leaking. Check the hoses if there is an odour coming from the toilet or shower.

To check for leaks, you can start by visually inspecting all waste plumbing components and connections. Use a flashlight to check for leaks inside enclosed tanks and pipework. Listen for unusual gurgling noises from drains, which often indicate drain line issues, and knocking or clanging pipes, which can mean trapped air and gases. You can also use your nose to detect sewer smells, starting outside the RV and slowly working your way in, tracing the aromas to isolate the area.

If you find any leaks, it's important to repair or replace the affected hoses or connections immediately. Tighten loose connections, replace broken seals, and fix any cracks in pipes or fixtures. If you're unsure about your DIY skills, consider hiring a professional plumber to help you solve the issue.

Clean the toilet bowl

Cleaning the toilet bowl is one of the easiest ways to get rid of the sewage smell in your camper. Here is a detailed, step-by-step guide to help you with the process:

Step 1: Prepare the necessary tools and supplies

Before you begin, make sure you have gathered all the necessary tools and supplies. This includes gloves, a toilet brush, cleaning solutions, and a sewer hose or pipe long enough to reach the disposal station. It is also recommended to have a tank wand for thorough cleaning.

Step 2: Inspect the toilet for any cracks or openings

Before cleaning, carefully inspect the toilet for any cracks or openings, especially on the toilet seat. These openings can allow odours to escape into your camper. If any cracks or openings are found, make sure to repair or replace the affected parts.

Step 3: Clean the toilet bowl

Start by cleaning the toilet bowl thoroughly. Use a toilet brush and a suitable cleaning solution to scrub away any dirt, stains, or build-up. Pay special attention to the rim and the underside of the drop seat, as waste and toilet paper can get stuck in these areas and cause odours.

Step 4: Disinfect and deodorize

After cleaning, it is important to disinfect and deodorize the toilet bowl to eliminate any remaining bacteria or odours. You can use an enzyme cleaner or a deodorizer in the form of drop-in pills, liquids, or powders. Follow the instructions on the product labels for proper usage.

Step 5: Regular maintenance

To prevent future sewage smells, perform regular maintenance on your toilet bowl. This includes cleaning it at least once a week and inspecting it for any cracks or damage. Additionally, always use enough water when flushing to prevent waste buildup. If you notice any issues, address them promptly to avoid bigger problems down the line.

By following these steps, you can effectively clean your toilet bowl and help eliminate sewage smells in your camper, creating a more pleasant and comfortable environment for your camping trips.

Check for vent system obstructions

Sewer gas in a camper is not only unpleasant but also dangerous, as it can be ignited, leading to a fire or explosion. If you detect a sewer gas smell in your camper, it is important to take immediate action to identify and address the issue. One crucial step is to check for obstructions in your vent system. Here's a detailed guide to help you through the process:

The vent system in your camper plays a vital role in maintaining proper airflow and preventing sewer gas buildup. Here are some steps to ensure there are no obstructions in your vent system:

• Rooftop Vent Caps Inspection: Begin by checking the rooftop vent caps. Climb up to the roof of your camper and carefully inspect the vent caps for any signs of debris, leaves, or bird nests that could be blocking the vents. Clear away any obstructions you find.
• Detaching Vertical Vent Pipes: If you plan to store your camper for an extended period or anticipate long drives, consider detaching any vertical terminating vent pipes. This prevents blockages from forming during storage or due to road debris.
• Checking for Blockages: Pay close attention to the vent pipes themselves. Insert a thin, flexible tool, such as a pipe cleaner or a flexible wire, into the vent pipes to check for any blockages or debris that may be obstructing the airflow. Remove any debris or blockages you find.
• Ensuring Proper Airflow: Once you've cleared any potential blockages, test the airflow by feeling for air movement at the vent openings. You can use a piece of tissue paper or a lightweight piece of fabric to help detect airflow. If there is still no airflow, there may be a more significant blockage that requires professional attention.
• Regular Maintenance: Incorporate vent system inspections into your regular maintenance routine. Before embarking on a trip, always check the vent system to ensure it is clear of debris and functioning properly. This proactive approach can help prevent future issues.
• Dual-Purpose Vent Filters: Consider investing in dual-purpose vent filters that serve two purposes: preventing blockages and absorbing gases. These filters can help maintain proper airflow while reducing the escape of sewer gases into your living space.
• P-Trap Waterless Guards: If you plan to leave your camper unused for extended periods, install P-trap waterless guards. These guards contain low-odor mineral oil and prevent evaporation, creating a barrier that blocks sewer gas from entering your camper.
• Visual Inspection: Conduct a thorough visual inspection of the vent system, including pipes, connections, and caps. Look for any signs of damage, corrosion, or loose connections that could contribute to obstructions or leaks. Address any issues promptly.
• Listening for Unusual Sounds: Unusual gurgling noises from drains could indicate drain line issues, while knocking or clanging pipes may suggest trapped air and gases. These sounds can sometimes indicate a blockage in the vent system.
• Odor Tracing: Start outside the camper and slowly work your way inside, carefully tracing any odors you detect. Sewer smells tend to intensify as you get closer to the source, helping you pinpoint the location of any potential obstructions or leaks in the vent system.

Remember, safety should be your top priority when dealing with sewer gas. If you suspect a significant obstruction or vent system malfunction, don't hesitate to seek professional assistance. By regularly checking for vent system obstructions and maintaining proper airflow, you can help prevent sewer gas buildup and maintain a safe and pleasant environment in your camper.

Clean the drain lines and pump stations

To get rid of sewer gas smells in your camper, it is important to clean the drain lines and pump stations regularly. Over time, sediment can build up inside the pipes, causing blockages and clogs. This can be done by following the steps outlined below:

• Locate the drain lines and pump stations in your camper. These are usually located near the black and grey water tanks.
• Inspect the drain lines and pump stations for any signs of buildup or blockage.
• If there is buildup or blockage, you will need to clear it out. This can be done by using a plumbing snake or a combination of baking soda and vinegar.
• Pour a pot of hot water down the drain lines and pump stations to help clear any remaining buildup or blockage.
• Flush the system with clean water to remove any residual debris.
• Inspect the system again to ensure that all buildup and blockages have been removed.
• If the system is clear, close the drain lines and pump stations.
• Repeat this process periodically to prevent future buildup and blockages.

By following these steps, you can help to ensure that your camper's drain lines and pump stations are clean and free-flowing, reducing the risk of sewer gas smells.
