- Pencil or marker
These tools will help you connect your RV toilet to a sewer line easily. Make sure to have them on hand before starting the process.
RV Sewer System Basics
Before you can plumb your RV toilet directly to a sewer line, it’s important to understand the basics of your RV’s sewer system. Unlike traditional homes, RVs have a holding tank that stores waste until it can be properly disposed of.
This holding tank is typically located underneath the RV and can hold anywhere from 20 to 100 gallons of waste.
Choosing the Right Sewer Hose
Several factors should be considered when choosing your RV’s sewer hose. The first thing you need to determine is the hose length you need. Measure the distance from your RV’s toilet to the nearest sewer connection point and add a few extra feet for flexibility.
Next, decide on the material of the hose. The most common materials are vinyl and rubber. Vinyl hoses are lightweight and easy to store but may not be as durable as rubber hoses. On the other hand, rubber hoses are more heavy-duty and can withstand higher pressure and temperature.
You’ll also want to look for a hose with proper fittings that will connect securely to both your RV’s toilet outlet and the sewer line connection point. Make sure to check that the diameter of the hose matches both connections.
Another consideration is whether or not you want a hose with a built-in sewer elbow. A sewer elbow is an angled attachment at one end of the hose that helps prevent clogs by creating a smoother flow of waste through the hose.
Finally, consider investing in a high-quality sewer hose that will last longer and perform better than cheaper options. While it may cost more upfront, it could save you money on repairs and replacements.
Finding the Nearest Sewer Line Connection Point
Finding the nearest sewer connection point is crucial when plumbing your RV toilet directly to the sewer line. This will ensure easy access to a proper disposal system for your waste.
To locate the nearest sewer line connection point, consult a map of where you plan to park your RV. Look for any nearby RV parks or campgrounds, as these are likely to have established sewer connections.
If you are not staying at an RV park or campground, you may need to do some additional research. Contact local sanitation departments or public works offices and inquire about available sewage systems and hookups. They may be able to provide information on nearby dump stations or other facilities that can accommodate your needs.
Another option is to use online resources such as Campendium or AllStays, which provide maps and information on RV-friendly locations, including dump stations and campgrounds with sewer hookups.
Once you have located the nearest sewer line connection point, ensuring your RV is parked nearby for easy access is important. You will also want to ensure that any hoses or pipes connected to your RV toilet are long enough to reach the sewer hookup without any kinks or bends.
By taking the time to properly locate and prepare a sewer line for your RV toilet, you can ensure the safe and efficient disposal of waste while traveling.

Dumping Your RV Tank at a Dump Station
Dumping your RV tank at a dump station is a common and convenient way to dispose of waste on the road. Most campgrounds and RV parks have dump stations available for their guests, but there are also stand-alone dump stations located throughout the country.
Dumping your RV tank at a dump station is simple and straightforward. First, you’ll need to locate the dump station at your campground or find a stand-alone one using an app or website like Sanidumps.com.
Once you’ve found the dump station, park your RV near it and connect your sewer hose to your RV’s waste outlet.
Next, place the other end of the sewer hose into the dump station’s inlet and open the valve on your RV’s black water tank. Allow all the waste to flow out of your tank until it’s empty. Then, close the valve on your black water tank and open the valve on your gray water tank to allow any leftover soapy water to drain out.
Once both tanks are empty, disconnect your sewer hose from your RV and rinse it out thoroughly with fresh water. Some dump stations have hoses available for rinsing, but bringing a separate hose along is always a good idea.
Finally, dispose of any used gloves or protective gear in a trash can and wash your hands thoroughly with soap and water.
Using Portable Waste Tanks
Portable waste tanks are a great alternative to directly connecting your RV toilet to the sewer system. These tanks come in various sizes and can hold anywhere from 5 gallons to 50 gallons of waste. They are designed to be easily transported and emptied at dump stations or other appropriate locations.
Using portable waste tanks is convenient for RVers who want more flexibility in where they camp. With a portable tank, you can stay at campsites that don’t have sewer hookups and still have access to a bathroom. Plus, it allows you to avoid the hassle and expense of plumbing your RV toilet directly to a sewer line.
When using a portable waste tank, it’s important to follow proper disposal procedures. First, ensure the tank is securely attached to your RV and that all connections are tight. Then, when the tank is full, take it to an approved dump station or other designated location for disposal.
Dumping the waste from your portable tank is easy. Simply connect the discharge hose from the tank to the dump station inlet and open the valve on the tank. Allow all the contents to flow out before closing the valve and disconnecting the hose.
Where does water come from to flush the RV toilet?
RV toilets require water to flush waste into holding tanks. The source of water depends on the type of toilet. Gravity flush toilets use water from the RV’s fresh water tank while macerating toilets grind waste with water from the RV’s fresh water tank.
Cassette toilets use a separate water tank for flushing waste into a portable waste tank. Proper installation requires turning off the water pump and flushing the toilet to remove pressure and water in the lines and bowl.
Are camper toilets usable without water hookups?
Camper toilets can be used without water hookups. For example, the Laveo Dry Flush toilet uses a liner to encapsulate waste; no water is required. Cassette toilets are portable toilets fixed in place with a black water tank that can be removed.
Water conservation techniques can also conserve water while using a traditional flush toilet.
How is an RV toilet connected?
An RV toilet is connected to a water supply line and a drain pipe. The water supply line can connect to an external supply or the RV’s water tank. A foot pedal or push-button electric flush mechanism can be used.
The contents of the toilet bowl go into a sealed-off black water tank, which needs to be regularly emptied at designated dumping stations. The water supply line can be 3/8″ or 1/2″ in diameter, and the correct size should be used to avoid leaks or other problems.
Make Your RV Trip Hassle-Free: Plumb Directly to the Sewer Line
Plumbing an RV toilet directly to a sewer line is an efficient way of disposing of waste when camping with your RV.
