UK delivery from £30. Fittings are despatched boxed. See delivery rates.
The Traditional Express double boss pipe has two 2″ BSPT threaded bosses on opposite sides of a short 100mm push-fit cast iron section, so two wastes can join the stack at one level.
It suits back-to-back bathrooms sharing a stack. Where the wastes arrive at right angles, use the 90° double boss pipe; for a single waste, the single boss pipe.
