The final look of the sump should be like this. But darn. My ATO doesn't work also. The ATO unit itself will light up, my pump works when connected separately but when it is connected via an adaptor to the ATO, it doesn't work. Tried the adaptor and it is also working leh. Will probably buy another adaptor in case the one I have doesn't
connect as well. Anyone knows here to get this kind of head which my ATO unit has? It has to connect to a 2 pin plug for the pump?
