Radiator bottom connection Sourcing 11PK for 500×1000 radiator

The Sourcing 11PK radiator bottom connection is engineered for use with 500×1000 mm panel and convector radiators to provide a concealed lower inlet/outlet. This unit enables plumbing to be routed through the bottom of the radiator, offering a tidier installation and compatibility with installations where side connections are impractical. The assembly is designed to match the physical dimensions of standard 500×1000 radiators and to integrate with existing mounting arrangements without altering radiator performance.

Advantages

The bottom connection simplifies pipe routing by relocating the inlet and outlet to the underside of the radiator, reducing visible pipework and improving the visual appearance of the installation. It allows for straightforward replacement or retrofitting of an existing radiator connection without requiring major modifications to the radiator body. The unit is produced to align with the specified radiator size, supporting consistent flow and sealing when fitted correctly.

Suitable for

• Domestic and commercial radiators sized 500×1000 mm
• Installations requiring concealed or underfloor pipework
• Retrofit projects where side connections need to be replaced
• Applications demanding a neat finish around the radiator base

Key specifications

• Designed for radiator size: 500 × 1000 mm
• Connection position: bottom inlet/outlet
• Compatibility: panel and convector radiator types matching the size
• Function: provides concealed lower plumbing connection for neat installations
• Material and finish: manufactured to suit standard radiator fittings and durable for plumbing applications

How to use

Fit the Sourcing 11PK bottom connection to the radiator’s underside following the radiator manufacturer’s guidance and standard plumbing practice. Ensure the radiator is drained and isolated before removing or fitting the connection. Align the assembly with the radiator’s connection ports, secure all fastenings, and apply appropriate sealing materials where required. After installation, restore the system, bleed air from the radiator, and inspect for leaks and correct flow.

Usage recommendations

Use qualified plumbing personnel for installation to ensure correct sealing and alignment. Verify compatibility with the specific radiator model and confirm that pipework dimensions and valves match the bottom connection to prevent flow restrictions or leaks.
