Hello, I am about to start doing the water installation of my house, so I wanted to know what tube measures to use for each case. The house has 2 floors, on the top floor there is a bathroom, on the floor under a small bathroom, in the kitchen would be the hot water tank, pothole and in the garage the automatic washing machine. The pipe would be hot melt. the water tank is 5m high approx. from the accommodation to the house and going up to the tank would be 1 "? from the tank outlet to the inside of the house of 1 "? the hot water to the 1" hot water tank and 3/4 "outlet? 3/4 "horizontal leads? and the rises to the tap of water or shower of 1/2 "? Could those measures be the right ones?
