Details

The McAlpine MAC-EXTB is a specialized straight extension designed to bridge the gap between a toilet and legacy plumbing. Specifically, one end features a multi-finned rubber seal engineered to fit perfectly inside 3.5-inch (90mm) internal diameter cast iron soil pipes. The opposite end is a plain socket designed to accept the outlet of a standard 110mm pan connector. Manufactured from durable EVA, this adjustable-length extension provides a secure, gastight transition. Consequently, it is a vital component for extending waste reach in older properties with narrow-gauge metal pipework.

Modernizing a bathroom in an older home often reveals a frustrating two-part problem: your soil pipe is set too far back, and it is a non-standard cast iron size. Specifically, a standard extension won’t fit into a 90mm cast iron pipe, and a standard pan connector won’t reach it. This often leaves installers trying to “bodge” together multiple parts, which significantly increases the risk of leaks and sewer odors. It is important to note that this extension does not fit directly onto the toilet pan; it is a middle-link solution. However, the McAlpine MAC-EXTB eliminates this struggle. Because it acts as a dedicated bridge, it securely grips the old metal pipe while providing a clean socket for your new pan connector. Therefore, you can achieve a professional, leak-proof extension without the cost of replacing the entire cast iron stack.
