In my last post I mentioned that you can have full RV hookups at a friends or relatives home installed. I only talked about the electrical and water connections in that post. In this post I will talk about sewer connections.
When you think of sewer you are probably thinking of the normal 3 or 4 inch sewer lines that you have to dig into the ground, and connect to the city sewer system or to a septic system. Well if it happens to be a very easy thing to do at the particular friends or relatives home where you are attempting to do this, there is nothing wrong with doing it this way. But in most cases you will be dealing with a paved driveway, or the fact that the sewer lines for the property are at the opposite sides of the house, and in that case you will have a problem.
So what to do in this situation? Well I am going to show you a solution that will make it as easy as running a water line. The solution involves something called a macerator pump.
Macerator pumps can be bought preassembled for RV use. The main problem is that most of the commercial units are one piece, and sometimes a bit to long to fit the sewer connections on a particular rig. In my case I built my own using a pump from a marine supply store, and a few fittings from a hardware store, and an RV store. The price came out to less than half of the commercial versions.
My home made macerator pump set up. This unit fits in the sewer compartment of my motor home, yet can be disconnected so that I can use a regular sewer hose instead.
The output of the pump can be connected to a regular 3/4 inch garden hose and pumped up to 150 feet. If you do not want to install any permanent connections, the garden hose can be inserted into any toilet. If you do this make sure the hose goes down around the bend in the toilet, and then stays put when you turn on the pump. The other easy way to go is to find the sewer clean out cap on the property, and insert the hose there.
But if you want to make a permanant connection that you can connect your pump to whenever you are parked you can cut into a sewer pipe inside the home and install a T fitting that has a 1 inch line off the side. From here you run 1 inch plastic line to where you want the RV connection to be. You can terminate the plastic line at your RV parking spot with a small adaptor that has a female garden hose fitting on the end. When you go to connect your RV you only need a short 3/4 inch garden hose to connect from the pump to this fitting. You can put together an appropriate length of hose with parts that you can find in any hardware store.
As with dumping at a sani dump, you want to dump your black water first and your grey water second in order to clean out the pump, garden hose, and the 1 inch sewer line.
In my book I give full instructions for building this pump set up, along with building it into your rig. There are pictures of the parts you will need, and some notes on wiring. I also talk a lot about how this pump will help you in boondocking situations.
