Details

The McAlpine MAC-EXTC is a specialized waste extension designed for narrow legacy soil pipes. Specifically, one end is fitted with a multi-fin rubber seal that fits securely into 3-inch (75mm to 80mm) internal diameter cast iron pipework. The opposite end is a plain socket designed to accept the outlet of any standard 110mm pan connector. This component acts as a high-security bridge, ensuring a gastight transition between modern toilet fittings and old metal stacks. Consequently, it is an essential problem-solver for renovations in older buildings.

Upgrading a bathroom in a heritage property often reveals a frustrating plumbing bottleneck: the original cast iron pipe is far smaller than modern standards. Specifically, a standard extension or connector will simply not fit into a 75mm or 80mm opening, often leading to messy, unreliable workarounds with sealant. Additionally, this extension is not designed to fit directly onto the toilet pan, which can lead to installation confusion. However, the McAlpine MAC-EXTC eliminates this struggle. Because it is custom-sized for narrow-bore cast iron, it creates a rock-solid, airtight seal that bridges the gap to your new toilet. Therefore, you can keep your existing pipework intact while ensuring your new bathroom is completely leak-proof and odor-free.
