Get that plumbing job done in no time with our quality sink and bath waste. Essential for both DIY and professional plumbers, the 40mm slotted sink and bath waste is an ideal replacement in black plastic to match your other fittings. Directions for use: Ensure the taps are fully closed. Disconnect existing pipework connected to the old waste body. Note: Take care against any potential water spillage on removal. Position the waste body (A) in the outlet hole of the sink/ bath, seating it on a bed of silicone sealant for a good seal. Only applicable to slotted waste traps - ensure that the overflow slots in the waste body face the integral sink/ bath overflow slots. Underneath the sink/ basin, place the remaining washer (B) with silicone sealant applied to both faces and screw backing nut (C) on the waste body and firmly hand-tighten. On ceramic sink/ bath, take care not to over-tighten to avoid cracking the sink/ bath. Reconnect pipework to the newly fitted waste body. Allow sufficient time for the silicone to cure and check for leaks.
