QUE SIGNIFIE BACKFLOW EN ANGLAIS
Retour arrière
Le reflux est un terme dans la plomberie d'un flux d'eau indésirable dans la direction inverse. Il peut s'agir d'un grave risque pour la santé de la contamination de l'eau potable en eau souillée. Dans le cas le plus évident, une citerne de chasse d'eau et son approvisionnement en eau doivent être isolés de la cuvette des toilettes. Pour cette raison, les codes de construction exigent une série de mesures et des dispositifs de prévention des rétrocauchés pour éviter tout reflux.
