How often do I have to empty it, and how?

Back to FAQ

It depends on the size of your container and how often you're there. For a single household user a 5–10 litre canister typically lasts about a week. When it's full you just lift it out, empty it — diluted, onto the garden, or down a drain — and give it a quick rinse. No mess.

The real bonus: because the urine no longer goes into your composting toilet, you empty that far less often — and that's the job nobody enjoys.

The Pi-Pi urinal is hardly any work. The smooth plastic surface wipes clean in seconds — with no plumbed-in flush water.

As needed (depending on use):

  1. rinse with a little water from a watering can or spray bottle
  2. apply an ordinary bathroom or all-purpose cleaner
  3. wipe with a soft cloth or sponge
  4. give it a quick rinse — done

Every now and then, a deeper clean:

  1. clear any deposits from the outlet
  2. use a vinegar or citric-acid cleaner against limescale and odour
  3. clean all surfaces including the outlet area and rinse

Good to know:

  • use soft sponges rather than steel wool or scouring powder
  • check the outlet runs freely from time to time
  • if you reuse the urine as garden fertiliser, clean with biodegradable products

In normal garden use the Pi-Pi urinal lasts many years with no parts to replace.

Yes, with no worries. The Pi-Pi urinal is frost-safe down to −40 °C and can stay in an unheated shed or outdoors all year round — you don't need to take it down or store it away for winter.

Tips for the cold season:

  • Drain any standing water: empty the trap and outlet so nothing can freeze in them
  • Easy to handle: if you do want to put it away — at ~1.4 kg it lifts off in seconds
  • Cover optional: the material is UV-resistant; a tarp only keeps the dirt off
  • No heating needed: with no water sitting in the urinal, there's no risk of frost damage

So your shed or cabin is ready to use again the moment winter is over.

Minor marks (scratches, scuffs):

Surface scratches can be smoothed out with fine sandpaper (grit 400–600). This doesn't affect how the urinal works.

Cracks or splits:

Because the Pi-Pi urinal is made from LLDPE, it can be repaired by plastic welding (hot air + LLDPE welding rod) — a local plastic-repair workshop can do this for you.

When a repair is no longer worth it:

  • cracks right at the mounting points or in high-stress areas
  • large-area damage (a crack longer than 10 cm) — a replacement makes more sense
  • several cracks, a sign of material fatigue

Prevention: thanks to the flexible material, the Pi-Pi urinal survives most knocks without cracking. The most common causes of damage are:

  • unsuitable, overly aggressive cleaning products
  • UV breakdown after many years outdoors
  • heavy knocks during transport or storage

Our warranty covers manufacturing defects — but not damage from improper use or unsuitable chemicals.
