Installing the rain water harvesting submersible pump

 With the toilet cisterns now connected up we need to fill the header tank in the roof space with rain water. The installation instructions for the rain water harvesting system say to leave the pump out until you are ready to install it. IIn the background you can see the cover is off the manhole into the tank. The pump assembly is ready with its float to keep the gauze mesh pick up point off the bottom of the tank and the blue cord to lower it into the tank (and retrieve it later if servicing is required!)
