Also worth having before you start

• Disposable nitrile gloves

  General guidance for any waste-contact job, not specific to one manufacturer: wear protective gloves and eye protection when you touch anything that has been in contact with human waste, and disinfect your tools and work surface afterwards. If you do not already have a box in the camper, get one before you start.

These are supplies, not replacement parts. We have not matched them to your model, because they do not need to fit anything.

Check this before you order

• Confirm your toilet is Aqua-Magic Style Lite or Aqua-Magic Style Plus.

• If it is Aqua-Magic V, order 31703 instead.
• If it is Aqua-Magic VI, order 31856 instead.
• If it is Aria Classic, Aria Deluxe or Aria Deluxe III, order 33384 instead.
• Check you need white — the other colours are different part numbers.
