Hot and cold water supply.

The supply pipelines may be installed on the rim of the bath or on the wall for connection to the bath tap. A drainage
overflow installation with water supply can also be supplied. Ask your dealer for Riho overflow-drain combinations with

In case of installation of a drainage overflow installation with water supply in the bath, an aerator water supply should be
installed in the supply line. This is to prevent dirty water from flowing back into the supply pipeline.
In case of doubt, consult a plumbing specialist.
