Potterton Apollo 25 30 Boiler Expansion Vessel Flexi Pipe 720066901

Product Overview

The Potterton Apollo Boiler Expansion Vessel Pipe (Part Number: 720066901) is a hydraulic connection component designed for selected Potterton heating systems.

The pipe forms part of the boiler's expansion vessel connection arrangement, providing a water connection between the expansion vessel and the sealed central heating circuit.

The expansion vessel accommodates changes in heating water volume as the system temperature increases. The connecting pipe allows the expansion vessel to remain hydraulically connected to the heating circuit.

Correct installation and sealing of the pipe are important for maintaining the integrity of the boiler's pressurised heating system.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished components should be professionally inspected and tested for damage, deterioration and leakage before installation.

Technical Insight & Common Failure Symptoms

The expansion vessel pipe is a hydraulic component that connects the boiler's expansion vessel to its central heating water circuit.

During heating operation, water expands as its temperature rises. The expansion vessel accommodates this additional volume, helping to limit excessive pressure increases.

The connecting pipe provides the hydraulic pathway required for the expansion vessel to perform this function.

Over time, the pipe or its associated connections may be affected by corrosion, mechanical damage, internal restrictions or deterioration of sealing components.

Possible signs that the expansion vessel pipe or associated components require inspection include:

• Water leakage around the pipe or its connections.

• Visible corrosion or deterioration.

• Cracks, deformation or physical damage.

• Damaged or worn connection surfaces.

• Loose or insecure hydraulic connections.

• Heating system pressure loss associated with leakage.

• Restrictions affecting the hydraulic connection to the expansion vessel.

These symptoms do not necessarily confirm a faulty expansion vessel pipe, as similar problems may result from damaged seals, expansion vessel faults, pressure relief valve problems or other hydraulic components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 720066901) is associated with selected Potterton Apollo 25 and Apollo 30 boiler systems.

Please verify the exact boiler model, GC number, part number, pipe configuration and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler expansion vessel pipes and associated pressurised hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the appliance and allow the heating system to cool before carrying out any work. The relevant heating circuit must be safely isolated and depressurised before removing the pipe. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
