Why Does My Camper Smell Like Sewer?

Camper smells like sewer

If your camper or RV smells like sewage, don’t worry – you’re not alone!

It’s the middle of summer and you’re out on the open road in your camper or RV, enjoying the scenic views and getting out to see some new sights. But then all of a sudden you realize that your camper or RV smells like sewer.

Is there something wrong with your vehicle? This is a common issue that many people experience but fortunately, there are ways to fix it.

Read on to find out what might be causing the smell and how to get rid of it.

Most Common Sources of Sewer Smell in Campers & RVs

1. RV/Camper Toilet 

If you’ve recently used the toilet in your camper or RV and there’s still a lingering sewage smell, it could be that the trap is dry. The trap is designed to hold water and act as a barrier to prevent sewer gases from entering the camper or RV. If it’s dry, simply pour some water into it and the problem should be solved.

2. Drains System

Another common source of sewer smell in campers and RVs is the drains. If you have a clog in one of your drains, it can cause sewer gases to build up and eventually escape through the drain vents. To clear a clog, you can use a plunger or a snake.

3. Holding Tanks 

The holding tanks in your camper or RV are where all the wastewater goes. If these tanks aren’t properly ventilated, the sewage can start to stink. Make sure the vent pipes are clear and unobstructed so that air can flow freely through them. You may also need to add more ventilation if the problem persists.

4. Septic Tank

If you have a septic tank, it’s important to have it pumped regularly. If the tank isn’t emptied on a regular basis, the sewage can start to back up and cause a nasty smell.

5. Sewer Lines

The sewer lines leading to and from your camper or RV can also be a source of sewer smell. If there’s a blockage in the line, it can cause sewage to back up and eventually start stinkin’! To clear a blockage, you can use a plunger or a snake.

How do diagnose and fix camper smells?

1.Figure out where the smell is coming from

The first step is to figure out where the smell is coming from. If it’s coming from the toilet, it could be that the trap is dry. If it’s coming from the drains, it could be a clog.

And if it’s coming from the holding tanks, it could be that they’re not properly ventilated.

2. Fix the problem

If there’s a clog in the drains, you can use a plunger or a snake to clear it. And if the holding tanks aren’t properly ventilated, you can try to add more ventilation.
