Hot and cold water is connected in the floor drain junction box via PEX hose in 25 mm empty pipes via type-approved cabinet penetrations.The PEX hoses are connected via half-couplings to external G15 threads in the water-proof junction box.
Drainage is connected to a 75 mm sewer line with sleeve.
The connection of the rattle pipe is via a 25 mm stud for leakage indication.Either the rattle pipe connection is used in the traditional way (type-approved in accordance with existing building regulations for leakage indication), or the rattle pipe connection is used for the installation of a wired leakage alarm or water safety switch that is placed, for example, in the control cabinet for water entering the floor drain. Read more about requirements below.
*The new regulation of the Housing Agency 'Hygiene, health and environment' - contains requirements on how leakage indication for tap water pipes is allowed - and is planned to enter into force on 1 January 2025. In the consultation process for this new regulation, both the Safe Water sum RISE updated rules that aim to allow more methods for leakage indication beyond 'visible' The existing wording reads as follows 'Joints on tap water pipes shall be positioned so that leaking water is quickly visible'.
RISE opinion for new regulation: "Joints on tap water pipes should be positioned in a way that allows quick detection of any leaks. Requiring visibility of leaking water is a limitation when there are also other methods that can be used to detect leaks early. e.g. leakage sensors, water failure switches, moisture indicators. Requiring visibility inhibits innovation."
Safe Water opinion and proposal for new wording in the new regulation: "Joints on tap water pipes shall be positioned so that any leaking water can be quickly detected and easily repaired.".

Enduce floor drain enables leakage indication according to existing and likely future water safety and leakage indication regulations.
