Replacing the hose connection for waste water
Connections for waste water can be of two types.
Flexible connection, which allow the making of turns at the outlet of the toilet bowl. It is important when ordering Flexible connection to verify that the hole diameter corresponds to your WC.
Solid straight connections , which allows the toilet to be installed directly into the duct for dirty water. This variant of installation is less common, because not always the layout of the furniture in the bathroom allows it.
