Resealing Bottle Traps are an alternative to Anti-
Syphon Traps (Silentraps) and may be used in
When the trap is subject to syphonic conditions
the automatic hydraulic action allows air to be
drawn through the inlet of the trap and through
the bypass columns thus breaking the syphonic
action. On cessation of syphonic conditions the
remaining water falls back to reseal the trap.
The Silentrap ventilates by drawing air through a
non-return valve, whereas the Resealing Trap
ventilates by drawing air through the inlet of the
trap and through the water seal.
The simple non-mechanical action ensures
retention of adequate water seal even under
extreme syphonic conditions
Eliminates the need for secondary ventilation
