why is my water heater leaking
Most water heater leaks come from fittings, the drain valve, or the temperature and pressure relief valve — all repairable for $15 to $350.

why is my water heater leaking from the top
Leaks from the top of a water heater almost always come from the cold/hot nipple fittings, the anode rod access port, or the temperature and pressure relief valve body — all repairable connection issues, not tank failure.

why is my water heater leaking from the bottom
Bottom leaks come from three sources: the drain valve, the end of the T&P relief valve's discharge tube, or a perforated tank from internal corrosion.
Repair soon
why is my water heater pressure relief valve leaking
A leaking pressure relief valve is usually responding to excess pressure — thermal expansion, house static pressure over 80 psi, or a thermostat set above 120 °F.

why is my water heater leaking water
Water near a heater often comes from an AC condensate line, a nearby washing-machine hose, or a softener drain — not the heater itself.

why is my water heater leaking from the drain valve
A leaking drain valve is almost always a warped plastic valve body or sediment caught in the seat, frequently appearing right after a tank flush.
Usually safe to investigate
why is my water heater leaking?
First, shut off power (breaker) or gas (control to OFF), then close the cold-water supply valve above the tank.

why is my water heater leaking from the overflow pipe
What people call the 'overflow pipe' is the discharge line for the temperature and pressure relief valve.
Repair soon
why is my water heater relief valve leaking
A slow weep from the relief valve usually means a worn seat or minor debris; a steady stream or repeated full discharge means dangerous overpressure or overheating.
Repair soon
why is my water heater overflowing
A water heater that's continuously discharging, not just dripping, means the relief valve is fighting a runaway condition — usually a stuck thermostat or failed heating element overheating the tank.
Dangerous — act now
why is my water heater dripping
An occasional drip, rather than a steady stream, usually points to a slightly loose fitting, a T&P valve weeping under mild pressure, or normal condensation.
Usually safe to investigate
why is my water heater leaking from the pressure valve
Water 'from the pressure valve' can actually come from three places: the valve body itself, a loose discharge-pipe fitting below it, or the tank threads the valve screws into.
Repair soon
why is my water heater overflow pipe dripping
An intermittent drip from the discharge pipe, especially after heavy hot-water use, points to a missing or waterlogged thermal expansion tank.

why is my water heater leaking at the bottom
Use elimination: dry and isolate the drain valve, T&P discharge tube, and tank base one at a time.
