Description
The Watts LFTP3T-AUS Trap Primer is a smart, low-maintenance solution to prevent sewer gas from entering buildings via floor drains. Designed for commercial kitchens, basements, plant rooms, and public amenities, this unit keeps drain traps sealed by automatically delivering a small amount of water into the trap during regular system use.
It works by sensing a 20kPa (3psi) pressure drop caused by water flowing to downstream fixtures. No adjustments, no guesswork — just reliable, automatic performance.
✅ Key Features:
-
20kPa Pressure Sensing Activation – Automatically triggers on downstream water use
-
No Adjustment Required – Set-and-forget operation with no manual calibration
-
Built-in Vacuum Breaker Ports – Protects potable water from backflow contamination
-
Lead-Free Brass Construction – Safe for potable water lines and AS/NZS compliant
-
Compact & Durable – Designed for tight commercial installs
-
Maintains Water Seal in Floor Drain Traps – Prevents odours and gas ingress
🏢 Ideal For:
-
Plant rooms and mechanical spaces
-
Commercial kitchens and food prep areas
-
Public toilets and change rooms
-
Hospitals, schools, aged care facilities
-
Any site with floor drains subject to drying out
💡 Why Trap Primers Matter:
In vented drainage systems, floor drains can dry out — breaking the water seal that stops sewer gas from rising into the building. The Watts LFTP3T-AUS ensures that every flush or use of nearby fixtures automatically tops up the floor trap, protecting your air quality and compliance.
