Final answer:
Primary water pressure tanks are equipped with a pressure gauge and a pressure relief valve.
Step-by-step explanation:
Primary water pressure tanks are designed to store and maintain the pressure of water in a plumbing system. In order to ensure safety and efficiency, these tanks are equipped with two essential components: a pressure gauge and a pressure relief valve.
The pressure gauge is used to measure and display the pressure inside the tank. It helps to monitor the water pressure and identify any potential issues.
The pressure relief valve is a safety device that automatically releases excess pressure from the tank to prevent any damage. It opens when the pressure exceeds a certain limit, allowing water to escape.
