What it is
The Ariston 65104340 is a by-pass pipe for Ariston standard water heaters. It sits within the appliance's water circuit and governs the path water takes around the main heat source, which helps the unit hold a steady outlet temperature and a stable flow rate. The pipe is supplied as an individual component and is fitted in place of the original item during repair or servicing work.
Signs this part needs replacing
- Reduced or uneven hot water output from the appliance
- Visible corrosion, scale build-up or pitting on the pipe surface
- Weeping joints or damp patches around the pipework
- Noise or vibration coming from the water circuit during operation
- Leaks traced to the pipe connections or its fittings
Before you order
- Confirm the part number against the rating plate on the appliance or against the component being removed
- Check the model and serial number of the Ariston water heater to confirm the pipe is the correct item for that unit
- Inspect the seals and washers at the connection points and renew them if they are worn or compressed
