Big Bertha The Fiat Ducato Motorhome Conversion

Understanding The Basics – Porta Pottis

Given their popularity for motorhomes and campervans, we thought it only right that we cover in more detail the Porta Potti range by Thetford.  We even have one installed ourselves in Bertha.  They are particularly popular for obvious reasons in self conversions due to their overall ease of installation – given that they don’t really need any at all. 

If anything was a case of unpack and go it is these!

Thetford’s Porta Potti range is known for being self-contained, easy to empty and hygienic, with no need for sewer connections — just add water and toilet chemicals to the tanks.

🧰 What makes them so popular?

Tank design: Thetford Porta Potti units typically consist of two snap-together parts —

  • Top tank holds fresh water for flushing
  • Bottom tank stores waste
    Separate tanks make them light to handle and easy to empty

Flushing systems:

Care products: Thetford recommends using their Aqua Kem Blue (waste tank chemical) and Aqua Rinse (flush tank additive) to reduce odour and keep parts clean.

  • Manual bellow pump — cheap, simple and reliable
  • Piston pump — gives a stronger flush if needed
  • Electric flush — most comfortable but heavier and pricier

Other Features

  • Carry handle on waste tank
  • Integrated pour out spout
  • Improved seating comfort (you’d be surprised)
