Does the end-of-line appliance exemption cover an inline shower filter?
Short answer
No. The exemption in § 1(2) No. 4 is narrow, and it exempts water — not the product.
Basis
The exemption needs an end-connected appliance that is not part of the installation, plus a necessary safety device TrinkwV § 1(2) No. 4
„Wasser, das sich in Fließrichtung hinter einer nach den allgemein anerkannten Regeln der Technik notwendigen Sicherungseinrichtung eines endständig an die Trinkwasserinstallation angeschlossenen wasserführenden Apparats befindet, der nach den allgemein anerkannten Regeln der Technik nicht Teil der Trinkwasserinstallation ist …“
English: water downstream of the safety device of an end-connected appliance that the technical rules do not treat as part of the installation.
The mirror provision moves the point of compliance, it does not remove it TrinkwV § 10(2)
„… an der nach den allgemein anerkannten Regeln der Technik notwendigen Sicherungseinrichtung …“
What to verify
An inline filter is in the flow path, has no safety device, and is not treated as an external appliance by DIN 1988-100 or DIN EN 1717. If a supplier argues the exemption, ask which safety device is installed and where the compliance point then sits.
