Do you need a 4” sewer hose with a T@B with a cassette toilet?

Welcome.  You will continue to find more and more that you will like about the new T@B. And yes, the T@B’s are “cute”😂

The thought of only having to use a black hose instead of a sewer hose is intriguing. While you can easily buy the connection for the T@B, I would have to do some browsing on Amazon to find the proper connections for the campground’s sewer connection, whether at the campsite or the sewer dump. Nevertheless, great insight!

Found it $8.89, on Amazon, but it’s probably available elsewhere.

OK, @Verna - how about 2 of these caps and a pipe adapter?

We have the cassette toilet.  So far we only have the adapter cap and a dedicated graywater hose (colored gray) to drain the graywater tank.  But, after our first camping trip last weekend, I'm looking at getting a regular sewer hose to drain the tank faster when we're at a busy campground dump station. I hate having to store that, so I'll probably get 2 adapter caps and a connection for the sewer cleanout for use at sites that have individual sewer hookups.

With a direct drain from my sink, I found that a standard water hose drained waaaaay to slow. That's why I adapted a standard sewer hose to hook up to my "hose" grey water drain connection.

I found using a "sump pump" drain hose was an easy compromise that allowed good drain flow without the bulk of a 4" black water hose.  One end is the 3/4 inch hose connection for the trailer and the other end can be adapted to various campsite drain openings. (Shown with a 4" screw in cap.)  It does require some creative adapting of various plumbing fittings.

@rfuss928  Thanks for sharing.  I'm going to try something like this!
