My Dopper is leaking

It goes without saying that the Dopper should not be leaking! You are right to look for information here. We need you to help us find out which part of the Dopper is leaking, because Dopper likes to replace parts instead of letting the entire Dopper go to waste. From a sustainable point of view, it is a shame having to throw away perfectly usable Dopper parts.

Please use the contact form to answer the following questions:

  • Thoroughly dry the Dopper with a cloth once and then fill it with water through the small opening. Is it still leaking?
  • Can you see a rubber sealing ring in the cap and does it fit properly?
  • Can you see a rubber sealing ring in the cup (the white part) and does it fit properly?
  • Can you see or feel any unevenness along the rim of the bottle (the bottom part).
  • Does the Dopper leaks between the cap and the white cup? Or between the cup and the colored bottle?
  • Has the Dopper been exposed to temperatures over 65°C?

Please make sure to enter your address in the contact form, so we know where to send any replacement parts to.
