What it is
A 175 mm flexible pipe manufactured by Vaillant, listed under part number 8000019518. It is used within the Arotherm PLUS /6 air-to-water heat pump family, where flexible connections absorb movement and vibration between rigid pipework and the appliance. The pipe carries water on the heating or domestic hot water circuit, depending on where it is fitted.
Signs this part needs replacing
- Weeping or visible water at the pipe ends or crimped connections
- Damp staining, corrosion or scale build-up around the fittings
- Kinking, flattening or crushing of the flexible section
- Unexplained loss of system pressure on the heat pump circuit
- Vibration noise or movement at the connection that the pipe no longer absorbs
Before you order
