Every close-coupled toilet hides one rubber doughnut between cistern and pan, and it is the most important component in the assembly. Compressed evenly it lasts decades; over-tightened it distorts and weeps within months. Fitting is a matter of moderate, even torque — not force. Tell your plumber. The Moly is a close-coupled suite built to that standard pattern, cistern seating directly onto the pan with no exposed flush pipe. It clears by washdown — gravity and volume rather than siphon suction — tolerating the low pressure typical of tank-fed supply. Traditional exposed-trapway body. Vitreous china, fired non-porous, glazed white. Elongated seat fitted. P-trap outlet for wall-level waste. Dual-flush. Complete suite: pan, cistern, seat and fittings.
