Description

A vacuum generating device, such as a wet/dry vacuum, is attached to a faucet by an attachment member. The attachment member includes a faucet connector, for connecting to the faucet, and a vacuum connector, for connecting to the vacuum generating device. The faucet connector and vacuum connector are fluidly connected by a conduit. The method for draining plumbing lines includes the step of shutting off the external supply of water to the plumbing lines. The vacuum generating device is then connected to a first faucet, and the valve to the first faucet is opened. The vacuum generating device is then activated and the valves to the remaining faucets are opened in order to create a pressure differential in the plumbing lines. The pressure differential causes water in the lines to flow into the vacuum generating device.

Un générateur de vide tel qu'un aspirateur de liquides et poussières est raccordé à un robinet. Le raccordement se fait au moyen d'un tube portant à un bout un raccord conçu pour s'adapter sur le robinet et à l'autre bout un raccord adapté pour se fixer au générateur. La méthode de vidange des tuyaux de plomberie proposée comprend les étapes suivantes : fermeture du robinet sur le branchement au réseau d'alimentation en eau, raccordement du générateur de vide à un premier robinet, ouverture de ce robinet, mise en marche du générateur et ouvertures des autres robinets pour créer une différence de pression dans les tuyaux, différence de pression qui forcera l'eau présente dans les tuyaux à s'écouler vers le générateur de vide.
