Worcester Bosch Boiler By-Pass Pipe Assembly 87161064370

Product Overview

The Worcester Bosch Boiler By-Pass Pipe Assembly (Part Number: 87161064370) is a replacement hydraulic pipe component designed for selected Worcester Bosch heating systems.

The by-pass pipe forms part of the boiler's central heating hydraulic circuit, providing a connection within the internal water circulation arrangement.

It is associated with the boiler's by-pass system, which provides an alternative water flow path under appropriate operating conditions.

Correct installation and sealing of the pipe assembly are important for maintaining the integrity of the heating circuit.

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 for damage, corrosion, restrictions and leakage before installation.

Technical Insight & Common Failure Symptoms

The by-pass pipe assembly is a hydraulic component associated with the boiler's water circulation system. It connects parts of the internal heating circuit and works alongside the associated by-pass valve arrangement.

The by-pass system helps maintain an alternative route for water circulation when required by the heating system's operating conditions.

Over time, the pipe assembly may be affected by corrosion, mechanical damage, restrictions or deterioration of its connections and seals.

Possible signs that the by-pass pipe assembly or associated components require inspection include:

• Water leakage around the pipe or its connections.

• Visible corrosion or deterioration of the pipe assembly.

• Cracks, deformation or physical damage.

• Damaged or worn sealing surfaces.

• Loose or insecure hydraulic connections.

• Heating system pressure loss associated with leakage.

• Restricted water circulation caused by an obstruction within the pipe.

These symptoms do not necessarily confirm a faulty by-pass pipe assembly, as similar problems may result from damaged seals, circulation faults, the by-pass valve or other hydraulic components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 87161064370) is associated with selected Worcester Bosch Greenstar boiler systems.

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

Safety Advice

Boiler by-pass 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 heating circuit must be safely isolated and depressurised before removing the pipe assembly. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
