When a water tank leaks from the top, the issue is typically caused by serviceable external plumbing connections rather than a structural tank failure. Common culprits include loose dielectric nipples, corroded hot water outlet or cold inlet pipe fittings, a leaky temperature and pressure (T&P) relief valve discharging due to thermal expansion or high pressure, or a loose expansion tank connection. These top leaks can usually be repaired easily by tightening connections or replacing valves. Verification: Wipe fittings dry with paper towels to pinpoint the exact leak source.
