Wastop Residential

Peace of mind with Wastop ® Residential Non return valve

When sewer systems become overloaded the point of least resistance becomes an emergency outlet for the sewer. This point can be in a basement or low lying homes, through the toilet, shower, drain or hand basin. Wastop ® Residential protects your home from flooding and back-flow caused by overloaded sewers.

Wastop ® Residential is available in two sizes to suit standard drains- 110mm (4″) and 160mm (6″).


  • Easy installation – no gluing or levelling
  • Pulsating flow minimizing the risk of clogging
  • Unique heavy duty memory membrane
  • No moving parts  – virtually maintenance-free
  • Stops liquids, odours, insects and small animals
  • Peace of mind – stops flooding effectively
  • The market leader – driving innovation
  • CE Approved  for use in residential applications


WaStop R is certified for use in sewer applications according to CE SS-EN-13564.

ACE also run a distributor network to cover the Wastop R residential range, to allow quick access via local suppliers. For Wastop R requirements, please contact your local supplier.
