This can be the result of one of two things:
- The waste has not been sealed adequately to the basin / bath and the water is passing around the waste (not through it). This water passing around the waste is still captured by the underside of the waste and conveyed into the drainage, therefore no leak will appear. The installing plumber should be contacted to rectify this fault. Click link for video of how to check this.
- The mechanism in the Pop Down® or Quattro Pop Up waste is not functioning correctly. Contact Art Plastics / Wasteland to request assistance. Please refer How to remove the Pop Down® mechanism video on the sidebar area to check this.
