Is it true or false that shut-off valves should be installed on connections to each pressure tank?

Shut-off valves are indeed essential components in HVAC systems, especially when dealing with pressure tanks. Installing shut-off valves on connections to each pressure tank is important for several reasons.

Firstly, shut-off valves allow for maintenance and repair work to be performed without having to drain the entire system. This is particularly crucial in situations where multiple pressure tanks are in use, as it enables technicians to isolate one tank while keeping the others operational.

Secondly, in the event of a malfunction or pressure surge, these valves provide a means to quickly isolate the tank, enhancing safety and preventing potential hazards related to overpressure conditions. Properly functioning shut-off valves can also prevent backflow, which can lead to contamination of the system.

Thus, incorporating shut-off valves as standard practice for each pressure tank is not only good design but also aligns with safety regulations and maintenance protocols in HVAC systems.
