We started laying in the various water pipes in and around the hot water tank. It is quite a tight space to route all the pipes like for example the Mains Water pipe across into and up the corner to the roof ready to go outside to the header tank, as well as the rain tank pipe to the same place. Then other pipes have to come down from the roof to connect to the hot tank and beyond to sinks and cisterns. It is quite a jigsaw of pipes!
