The Americanizer™

The Americanizer™ – RV Sewage Adapter for Cassettes and Portable Toilets IS HERE!

And yes, that’s our own affiliate link… it’s our product!

At long last, we’ve managed to get the Americanizer™ listed and live on!  You can order yours now.  At present, we’re working as fast as we can to get them packaged up to Amazon standards and shipped to their warehouses.  It’s been a learning experience, to be sure.  If you happen to see an “out of stock” message during these early days, don’t despair!  More are coming as fast as we can make it happen.  We’d like to thank all of you who have stuck with us all the way through the product development and production process.  It’s been quite an adventure since we sent out our initial feelers.  We hope it was worth the wait!

So, to quickly reiterate what the Americanizer is and what it does:

  • The Americanizer™ is the only adapter for Thetford brand cassettes and portable toilets that will connect your cassette’s dump spout with standard RV sewer accessories.
  • It doesn’t permanently modify or damage your cassette or portable toilet in any way.  You can still dump in all the places you dump it now.  This just adds more options.
  • The Americanizer™ is constructed in such a way that the waste never actually flows through the adapter.  It goes straight from your cassette or portable toilet into the sewer hose.  It might not stay pristine clean, but it’ll be close.
  • You don’t have to grab the “business” end of The Americanizer™ to attach or detach it.  It’s long enough that you operate it from the upstream end.
  • The Americanizer™ has an easy-grip barrel which makes it easy to grip, even with gloved hands.

You can learn more about The Americanizer™ in the original concept video below:


We’ve only tested The Americanizer™ with Thetford brand cassettes and portable toilets, but we’d like to start a list here of all the different models of cassette that others have successfully used it with.  If your cassette model is not listed here, and you’ve successfully used The Americanizer™ with it, sound off in the comments below and we’ll update the list.

    Yes i am very interested in this as a new camper owning a
    TAB 320 S trailer and your adapter makes total sense on dumping one of these cassette toilets

    Hi James!

    What an absolutely great idea! I have over 30 years of experience of travelling in European style caravans and motorhomes and have always hated to empty our Thetford cassettes. So; when I saw your product I ordered it straight away and got it delivered very quickly to a reasonable cost. What a great product if it weren’t for a tiny detail… In our latest motorhome we’ve got, for the first time for us, a cassette toilet that isn’t a Thetford cassette but a Dometic CT 4110. Sadly, I didn’t realize this until I couldn’t fit the Americanizer… Do you have any plans for make an adapter to fit our cassette? Can we help in developing this by 3D-printing a prototype to test fit? Please contact us if you’d like to take this any further. Best regards from a fan of yours in Sweden.

      I’ve received several requests for a Dometic (or Camco, here in the US) version of the product.
      I’ll investigate this, and any updates I come up with will be posted here. But first… I’ll have to find myself a Dometic toilet to test with!

        Is there anything I can do to help? As owner of a Dometic cassette maybe there’s something I can do with the cassette we already have?

        Well, I’ve never even seen one, so we could start out with a picture and some rough dimensions I suppose. Can you post pictures here? Or on some other platform. Whatever works for you.
