We have done more plumbing work. All the pipes now are connected to the tank and the mixer and only need the water pump to finishing the job. We used a domestic mixer that has 2 ports, one for cold water and the other for hot. We fitted a valve at the end of each pipe so we can use the cold water pipe for the water supplied by the pump and the hot water pipe we can use for the main water supply. The only that we have to do is close the added valve on the port that it is not in use. Follow the build in Instagram https://www.instagram.com/freetasman/
