Can You Hook Up an RV to a House Sewer?

RVs have black water tanks to store the wastewater from the toilets. Many people directly hook it up to the house sewer system to reduce the dumping effort. These recreational vehicles are like your home and have toilets, sinks, faucets, and showers. It shows that you also need the holding tank for wastewater storage.

Can You Hook Up an RV to a House Sewer? You can hook up an RV to a house sewer by locating the sewer clean-out in your home. Use the hose and connect it to the RV, remove the cap from the sewer clean-out, and attach the other end of the hose with it. People do this for convenience, save money, extend stay time, reduce mess, for home-like comfort, reduce freezing of lines, no need for a blank tank, avoid long lines at dumping stations, and low maintenance.

You should get permission from the local authorities because the house waste management system was connected to the town’s local sewer lines. However, I have also seen many people attaching their RVs to the campground stations to reduce the effort of dumping holding tanks.

How do you hook up an RV to a house sewer?

You need hoses, adapters, and a support system to attach the RV to the sewer system. You have to park it in the nearby location to direct the smooth flow from the pipe.

Moreover, you should park your RV on a leveled ground surface. Check the faucets, sinks, showers, and toilets to ensure that these are free from leakages.

You have to locate the clean-out in your home, the main pipe connected directly to the city’s sewer system. It is the 4-inch pipe usually located in your home’s basement and garage.

It has a screw cap to reduce the risk of smell, and other off-gasses emerging outward. Check the hose and ensure it is free from all obstructions and present at the accessible location so you can connect the pipe directly with it.

I also did this and cleaned the area that surrounded the clean-out. I used the brush to remove the debris to ensure a tight connection.

I also measured the distance between the hose and the RV to select the pipe accordingly. I connected one end of the sewer hose to the RV outlet and secured it with an adapter.

I attached the other end with the clean-out after removing its cap. I also used sewer hose support to direct the downward flow, reduce the leakage, and ensure smooth flow.

You should ensure the tight connections of hoses from both ends and check leakages before using the toilets, showers, or sinks in RVs.

Is it legal to hook up an RV to a house sewer?

It is necessary to check the rules and regulations in your city or town while hooking up the RV to the local sewer system to avoid inconveniences and fines.

You can attach it to the house sewer system in areas that locally allow it. You need legal permission because the house waste management system is connected to the city or town’s sewer lines.

Residential areas have the clean-out, and you have to connect the pipe with it. Check the rules and regulations by contacting the legal authorities of your area.

You can see legal troubles for not following the rules and regulations.

Why would you hook up an RV to a house sewer?

Holding tanks in your RV has limited space, and you have to dump them when they become full. Attaching it to the house sewer is better because it has unlimited capacity and reduces your effort to dump the tank frequently.


Many people prefer to attach the RV waste management directly to the house sewer system for convenience. You have to connect its pipe and do not have to dump it frequently.

Black water holding tanks contain the level indicators to give information about their filling. You have to check the level indicators frequently and dump the black water tank when it becomes full to avoid smell and leakage inside the cabin.

In addition, it is a convenient way to dispose of the wastewater from the toilets instead of connecting it with the dumping station.


You have to pay while using the public dumping stations to empty the black holding tanks. It is not a cost-effective procedure during road trips because of frequent dumping.

It increases your overall trip cost when you have to stay at the same place for multiple days. However, connecting the RV with a house sewer system or campground station saves you money.

You can save your costs while using public dumping stations to remove waste.

Extend stay time

Many people plan their trips according to the availability of the accessories and convenient features in their RVs. My friend told me he did not plan a trip for more than 4 to 5 days because of the increase in the overall cost.

In addition, he had to dump the blank tank, which was a hectic and irritating procedure for it. I told him to attach the RV outlet with a campground station to reduce fatigue.

Moreover, it can also increase your stay time at a certain place. You can stay at your desired place longer without worrying about any issues.

Reduce mess

Emptying the black tank of your RV is irritating because of the smell and mess. People usually avoid doing it because it is messy and unpleasant because of the smell and waste presence.

Connecting the RV outlet to the sewer reduces the dumping mess. In addition, it requires little or no maintenance, and you do not have to check it frequently.

You have to connect the pipe at once and then leave it for its functioning. The blank tank requires high maintenance to reduce the leakages and smell, which is time-consuming.

It also gives people a home-like feeling and convenience because they do not have to worry about waste disposal management protocols.

Reduce freezing of lines

RV line freezing is common during cold weather, which affects the normal water flow. The water inside the holding tank freezes, and expansion causes cracking of the tank.

In addition, you can also see the freezing of plumbing lines during cold weather when water does not pass through them constantly.

Hooking the RV to the house sewer system reduces freezing when the temperature becomes extremely low because of continuous water movement through lines.

It is a better option for people who plan tours in extremely cold areas.

No need for a black water tank

You do not have to mount the black holding tanks in your RV when you want to hook them with sewer or campground stations.

It also reduces your fatigue during the tour, which you require for their dumping, cleaning, and maintenance. In addition, the removal of the black water tank also frees up plenty of storage space.

Furthermore, it also reduces the overall weight, which improves the fuel economy of towing vehicles.

Avoid long lines at dumping stations

Public dumping stations remain crowded during peak times because of the more RVs on the road. People love to plan their trips in the mid-summer or spring season because of the pleasant weather and the few issues in this specific weather.

You do not have to wait in the lines of the dumping station when you hook up the waste system with the house sewer. When you connect them with a hose, waste material directly goes to the sewer pipes.

It becomes a convenient option for you, and you can also save time. You can spend that time visiting and exploring new places instead of waiting in lines.
