In those baths, we have 6 toilets, 6 showers, 2 bathtubs, and 10 sinks. Also, as a part of the plumbing system, we have 3 zones of sprinklers and a pressure system.

To begin to understand how the plumbing system works in Mexico. Let’s first “Take it to the street.”


At the street, you will probably have a meter such as this for your water service. If it’s spinning, that means water is actively running into your house. Know the city feeds that water by a company named Japay. Unlike the USA, this water does not run on every street every day or all the time. Sometimes the water will flow to some streets, and others will flow to different streets. This is the first major difference in the plumbing system in Mexico vs. that of the United States. In the states, we have a main water line from the street that goes into a meter, usually in the ground, and then to your house. There is the main cut-off valve to the meter, but in general, the water pressure is good enough to provide water to your entire house all the time. You actually have a pressure regulator to decrease the pressure coming in from the streets in the states.
