The expansion tank should be installed on the cold water supply side before the water enters the hot water tank. This location is crucial because it allows the expansion tank to function properly by absorbing pressure increases caused by the heated water. Directly installing it on the hot water side could lead to less efficiency and potentially stress on the hot water tank's structure. Ensuring it's placed correctly helps maintain a balanced pressure throughout the system, safeguarding against damage and leaks.
