Step 1: Locate the water supply valve:

1. Begin by locating the water supply valve, which controls the water flow to the toilet. This valve is typically situated on the wall or floor near the toilet. Take a moment to familiarize yourself with its location.
   

Step 2: Turn off the water supply:

1. To accurately measure the water pressure, you must first turn off the water supply. Rotate the valve in a clockwise direction until it is fully closed. This action will prevent water from flowing into the toilet during the testing process.
   

Step 3: Flush the toilet:

1. With the water supply turned off, flush the toilet to eliminate any remaining water from the tank and bowl. This step ensures that your pressure reading reflects the true incoming water pressure when the valve is reopened.
   

Step 4: Attach a pressure gauge:

1. Obtain a pressure gauge designed for measuring water pressure and attach it to the water supply valve. Most pressure gauges have a threaded end that can be easily screwed onto the valve. Ensure a secure connection between the gauge and the valve.
   

Step 5: Turn on the water supply:

1. Slowly open the water supply valve by rotating it counterclockwise. This action allows water to flow into the toilet tank. Gradual opening of the valve helps prevent pressure surges and provides a more accurate reading.
   

Step 6: Read the pressure gauge:

1. Once the water supply valve is fully open, the pressure gauge will display the water pressure in PSI. Observe the gauge closely for a stable reading. The pressure should meet or exceed the minimum requirement of 35 PSI for optimal performance of a smart toilet.
   

Step 7: Note the water pressure:

1. Take note of the water pressure reading displayed on the gauge. If the pressure is equal to or greater than 35 PSI, your smart toilet should operate efficiently. However, if the pressure falls below this threshold, it may be necessary to address the issue to ensure proper functioning of the toilet's features.
   

Step 8: Adjust the water pressure (optional):

1. If the water pressure is too high or too low, you may need to make adjustments. Consult a professional plumber or refer to the instructions for your water pressure regulator, if applicable. It's important to address any pressure-related concerns to maintain the longevity and performance of your smart toilet.
   

Step 9: Turn off the water supply:

1. After completing the water pressure check, turn off the water supply valve by rotating it clockwise until it is fully closed. This step prevents unnecessary water flow and maintains the integrity of your plumbing system.
   

Step 10: Remove the pressure gauge:

1. Unscrew the pressure gauge from the water supply valve carefully. Store the gauge in a safe place for future use.
   

Regularly checking the water pressure of your smart toilet ensures optimal performance and avoids potential issues. By following the step-by-step guide outlined in this article, you can easily measure the water pressure and ensure that it meets or exceeds the minimum requirement of 35 PSI. If you encounter persistently low water pressure or face difficulties in adjusting it, it's advisable to seek assistance from a professional plumber who can provide expert guidance and solutions tailored to your specific needs.
