Why Is My Water Heater Leaking?

Leak location tells you almost everything about whether the fix is a part swap or a replacement.

Leak at the top of the tank. The most benign scenario. Top-of-tank leaks typically come from loose or corroded inlet/outlet connections, a cracked flex connector, or — in older Palo Alto homes with original galvanized nipples — a corroded cold-water inlet nipple. These are repairable. Water heater leaking repair palo alto calls that originate from the top connections are usually straightforward same-day fixes.

Leak at the T&P valve (side of tank, usually mid-height). The temperature and pressure relief valve is discharging, which means it’s doing its job — but either the water pressure in your home is too high, the thermostat is set too hot, or the valve itself has failed and is weeping without cause. This is repairable if the valve has simply worn out; it’s a diagnostic flag if pressure or temperature is the root cause.

Leak from the drain valve (bottom front). Drain valves on older units corrode and drip. If the valve body is intact, it can be replaced. If the threads have corroded into the tank, the repair becomes more complex — but it’s still often possible.

Leak from the tank body itself (anywhere on the body surface, or underneath with no other source). This is the one that means replacement. Steel tank bodies corrode from the inside out, and once the wall is breached, no sealant or repair patches the liner. A tank body leak means the unit is done. If you’re seeing water pooling directly under the tank body — not from a valve or connection — call us and plan for a same-day replacement conversation.

Is It Worth Repairing a Water Heater or Replacing It?

The repair-or-replace calculation has two variables: the unit’s age and the cost of the repair relative to replacement.

Repair is typically the right call when:

• The unit is under 8 years old and a single component has failed
• The repair cost is under 30–35% of installed replacement cost
• The tank body is structurally intact (no corrosion breach)
• The failure is a serviceable part: thermocouple, heating element, T&P valve, anode rod, gas valve

Replacement makes more sense when:

• The unit is 10+ years old and a major component (gas valve, heat exchanger) has failed
• Repair cost exceeds 40–50% of replacement cost
• The tank is leaking from the body
• You’ve already repaired the same issue twice in 12 months

The timing variable specific to Palo Alto is the BAAQMD’s January 1, 2027 ban on new gas water heater installations. If you’re repairing a 9-year-old gas unit in 2026, the next replacement must be electric — and planning that electrical work proactively is very different from doing it in an emergency. Our Palo Alto water heater replacement page covers that decision in more detail.

No Hot Water Repair and Common Palo Alto Service Calls

No hot water is the most common water heater repair call we receive, and the cause is different for gas and electric units. Water heater not heating repair palo alto calls fall into two clear diagnostic tracks.

No hot water — gas water heaters: The pilot won’t light or won’t stay lit after lighting. In almost all cases this is a thermocouple or thermopile failure — a small, inexpensive part that tells the gas valve whether the pilot flame is present. Less commonly, a failed gas valve prevents ignition even with a working thermocouple. A burner assembly clogged with debris (common in garage and exterior units during Palo Alto’s dry summer months) can also block ignition. We clear, test, and identify the component on the diagnostic visit.

No hot water — electric water heaters: Check the circuit breaker first. Electric water heaters draw significant amperage and will trip a breaker after a power surge. If the breaker resets and the unit still doesn’t heat, one or both heating elements has likely failed. Upper elements and lower elements fail independently; if only cold water comes out, the upper element is suspect. If you get a small amount of hot water that runs out quickly, the lower element is typically the issue. Both are same-day repairs.

No hot water — tankless units: Tankless water heater repair Palo Alto calls on gas-fueled units most often involve scale buildup on the heat exchanger — a consequence of Bay Area water’s mineral content and skipped descaling maintenance. Annual descaling prevents this; a descaling service resolves it.

For no hot water repair palo alto calls, same day water heater repair palo alto is available Monday through Saturday. Call (415) 359-4588 and a licensed plumber will give you a time window for the same day in most cases.
