Cutaway illustration of house with plumbing plan This is a cutaway of a house with its plumbing plan illustrated.  On the top floor of the house, there is a tank of water.  This solar tank is drawing water from a tank located outside of the home, under the road.  The water leaving the tank travels to a shower in a bathroom on the second floor, to a sink on the main level and to a washing machine in the basement.  There is a small pipe leading to a main floor bathroom as well.  Water is pictured leaving the home and running to an automatic sprinkler system in the yard. bathroom drawings stock illustrations
