Pan Connectors
A pan connector seals the outlet of a toilet pan to the soil pipe, taking up the misalignment you get when refitting a bathroom or moving a WC. Flexible, offset and extension toilet pan connectors let the pan sit square without cutting into the stack. Connects to push fit soil pipe.

Frequently Asked Questions
110mm is the standard for a house stack taking a WC. 160mm is for a stack serving several flats or a commercial building where 110mm would be undersized. Waste-only runs from a basin, bath or sink use 32mm, 40mm or 50mm depending on the appliance, and join the stack through a boss.
Yes — without air entering the stack, a discharging WC can siphon the water seal out of nearby traps and let drain smells into the room. Traditionally the stack runs open to above roof level. An air admittance valve is the alternative where taking the stack through the roof is not practical, but at least one stack on the system should stay open.
Push fit seals on a ring, so a run can be dismantled and reused and there is no curing time — useful for a repair, or anywhere access stays open. Solvent weld is cemented rigid at every joint, which suits a stack that will be boxed in or a run sealed behind plasterboard, where a creeping seal is a real problem.
