Installation hygiene and safety

The trap's most important function is to provide an air gap between the softener discharge and the sewer system. This key protective feature reduces the risk of wastewater being drawn back into the unit.

The trap therefore helps protect the softener and plumbing by providing safe backwash drainage and supporting correct operation of the water treatment system.

Trap applications

The trap is an important fitting when installing a water softener. It connects two essential drains to one sewer outlet.

  • Draining backwash from the control valve: water discharged after media regeneration.
  • Draining the brine tank's emergency overflow.

The backwash trap maintains hygienic separation between the softener discharge and the sewer. Its water odour seal helps prevent unpleasant smells from entering the room.

Easy installation and compact design

The trap has a 40 mm side outlet for convenient connection to standard drainage plumbing. Its compact shape makes installation easier even where space is limited.

The simple design allows the softener hoses to be connected quickly to the appropriate trap inlets, followed by connection of the trap outlet to the drainpipe.
