What it is
The Andrews 7709350 is a 90-degree, 28mm flow pipe for the upper/twin heat exchanger rated at 120kW. It is used in Andrews water heaters, including Maxxflo EVO models, to route water through the heat exchanger. The pipe forms part of the hot water circuit and must match the appliance's flow configuration.
Signs this part needs replacing
- Visible water leaks or weeping at the pipe joints or along the pipe body.
- Corrosion, pitting, or scale deposits on the pipe surface.
- Reduced hot water flow or inconsistent temperature from the water heater.
- Overheating or kettling noises linked to restricted flow through the heat exchanger.
- Repeated lockouts or performance faults traced to the upper/twin heat exchanger circuit.
Before you order
- Confirm the appliance model is an Andrews Maxxflo EVO 120/302 or 90/302, or an Andrews hot water spares application.
- Check the existing pipe is 28mm and a 90-degree upper/twin heat exchanger flow type.
- Verify the part number 7709350 matches the current component.
- Check whether any seals or washers are required separately for the joint.
