The 50-Gallon Reservoir vs Continuous Line Leaks
A common misconception among homeowners is that upgrading to a tankless on-demand water heater eliminates the risk of indoor water damage. While it is true that tankless systems do not harbor a 50- to 80-gallon reservoir of pressurized water ready to rupture at any moment, they are connected to continuous municipal water supplies under identical pressure. A ruptured copper heat exchanger or split braided stainless supply line on a tankless unit will flood a home just as rapidly as a conventional tank if not equipped with automated shutoff devices.
