Part Number:
Designed and made in New Zealand, TruDesign Vented Loops are the superior composite siphon break solutions for marine applications. Vented Loops prevent water siphoning from underwater skin fittings back into a vessel and thereby guard against accidental flooding and sinking. Vented loops are used predominantly in toilet to overboard applications, toilet inlet applications and holding tank to overboard applications. They can also be used in genset or small engine inlet cooling water systems. The simple one way breather valve at the top of the vented loop allows air to enter the line when not in use, thereby preventing siphoning - and yet seals when water or waste passes through the loop. The duckbill one way valve is designed to seal even when particles are present in the fluid. Vented Loops are moulded from a high-strength, highly inert Polysulfone core overmoulded in Polyproplene.

  • Silicone duck bill valve - Long life with no perishing or hardening
  • Constant internal diameter - No reduction in flow
  • Self-contained mounting - 3 screw mounting posts give secure and easy installation
  • Chemical resistant - Impervious to waste water and common toilet cleaning products
  • UV resistant - These fittings will not break down with ultraviolet light or discolour from the sun
  • High quality surface finish - Will not discolour with green film as similar bronze fittings do
  • Large operating temperature range - Suitable for all marine environments, from -20∞C to +100∞C

    It is recommended that the electronic Vented Loop with Solenoid (on following page) be used on the intakes of electric pump toilets and that the two are wired together so that the Solenoid closes upon pump activation preventing the draw-in of air. When the pump deactivates, the solenoid opens and breaks any siphon.
