The 110mm Terracotta Rectangular Drain Inlet Hopper is generally used in conjunction with P traps.The hopper head is connected via the spigot which push-fits into the P Trap. The rectangular hopper has two closed side bosses which when drilled out using a 50mm – 57mm hole cutter and boss adaptors are fitted will allow 32mm 40mm and 50mm waste pipes to be connected to the drainage system. More commonly waste pipes/downpipes are connected above ground via the grate which can be cut to suit the pipes.
