It’s fair to say that your home is one of the most important resources that you have, and it’s vital that you don’t get caught off guard by air or water malfunctions that may arise over time. The average person may not know much about how to keep their home in functioning order, but thankfully, Eyman is a champion of spreading the word so you can stay in control of your home at all times, whether it’s summer or winter in Nebraska.

And many times, the care that your abode requires is right at your fingertips if you know what to do and where to start. So, how do home mechanical systems like your home thermostat (HVAC) and main water shut-off valve (plumbing) work? What are they, and where do you find them?

Many homes nowadays are equipped with an HVAC thermostat: an outdoor HVAC (heating, ventilation, and air conditioning) unit connected to an indoor thermostat.

The thermostat is typically a small device with buttons, usually with a screen, found on a wall in a central location in your home, such as a living room or hallway. Some homes have multiple thermostats for more precise temperature control.

Together, the HVAC and thermostat components work together to automatically make your house hotter or colder. Your thermostat measures your home temperature with a built-in sensor, comparing the current indoor climate with your desired preset thermostat “setpoint,” sending electrical or wireless signals to the HVAC unit, and then automatically adjusting the air accordingly using the HVAC. In other words, the temperature will climb or descend to what degree you have the thermostat set to.

But what if your issue is plumbing related?

The main water shut-off valve is a crucial component of your plumbing system. It controls the flow of water into your home, allowing you to stop the water supply in case of emergencies or when repairs and maintenance are needed.

The main water shut-off valve is usually located where the water supply line enters your home. It is commonly found in basements, crawl spaces, utility rooms, or near the water meter.

There are different types of shut-off valves, including gate valves and ball valves. Gate valves are bi-directional and have handles that turn clockwise or counterclockwise to control water flow. Ball valves, on the other hand, are one-way valves with levers that need to be rotated 90 degrees to open or close the device.

When the valve is open, water flows freely into your home, allowing normal water usage. Turning the valve to the closed position blocks the water supply, cutting off the flow to your home’s plumbing fixtures.

In case of emergency situations, you will want to know the location of your main water shut-off valve. That way, you can quickly turn it off in case of a burst pipe, major leak, or other water-related emergency.

Locating the main water shut-off valve may require some creative exploration. The main valve’s whereabouts can vary depending on your home’s design and plumbing layout. If you’re unsure about the location, consult your home’s blueprint or consider contacting a professional Eyman plumber for assistance.

And in general, if you have specific questions about your home’s mechanical systems, it’s always best to consult the manuals or seek guidance from professionals who will be familiar with your specific setup.
