This pump & tank unit is for the disposal of grey water. The unit consists of an 45 Litre tank & pump combo featuring: Polypropylene Tank with ribbed sides for added strength, plus the ribs will anchor the tank if it is partially concreted in place. The tank has a heavy duty polypropylene lid, which is strong enough to walk on, plus the lid is full size allowing easy access into the tank for service. Inlet connection is a 110mm i.d. pipe socket, to suit a std 100mm waste pipe. (Adapters to suit other pipes sizes are available.). Installed in the tank is a Fully submersible type TPO1376A drainage pump with integral on/off level control, a 400wwatt 230v single phase motor, with built in overload and automatic reset, plus fitted with 10m cable with std 3pin plug. Also supplied is a 50mm PVC vent pipe connection. Pump max head 7m, and max flow is 6000L/Hr. On the pump outlet is fitted a brass non-return valve, and pipe nut for easy removal/inspection. The non-return valve prevents back-flow when the pump stops. Tank outlet pipe connection is screwed 1"BSP, into which you can screw in a wide variety of fittings/pipe. If the unit is to handle kitchen waste we recommend installing a grease trap on the inlet side (se our other listings).
