    How much does a water heater repair cost in McAllen, TX?

    The same posted price applies across McAllen and the rest of the Rio Grande Valley: $165-$425, updated September 22, 2026.

    Is it worth repairing a water heater or should I replace it?

    A repair in the $165-$425 range is worth it on a tank under about 8 years old with one failed part. Once a tank is older than that, or the tank body is leaking, replacement starting at $1,456.86 installed is usually the better spend.

    Rule of thumb: if the repair is between $165 and $425 and the tank is young and dry, repair it. If the tank is over 10 years old, rusting, or you would be paying for a second repair, put that money toward the replacement instead — a 50-gallon electric tank is $1,519 installed.

    How much to replace a water heater element?

    Replacing one failed heating element on an electric water heater is $275. A second element is +$125.

    How much to replace a water heater thermostat?

    Replacing one failed upper or lower thermostat is $225. A second thermostat is +$100.

    How much to replace a gas valve on a water heater?

    A gas water heater gas control valve replacement is $425.

    On an older gas tank the valve is often the most expensive part on the unit, so we will tell you honestly if replacement is the better value before you spend it.

    How much to fix a leaking water heater?

    A T&P relief valve replacement is $225. A leak at a water connection requires its own approved price. A leak coming from the tank body itself cannot be repaired and needs a replacement, which starts at $1,456.86 installed.

    If water is pooling under the tank right now, close the cold water valve on top of the heater and shut off the power at the breaker (electric) or turn the gas valve to OFF (gas).

    Why is my water heater not getting hot and what does it cost to fix?

    On an electric tank, one failed heating element is $275 and one thermostat is $225. On a gas tank, a thermocouple is $225 and a gas control valve is $425.

    Running out of hot water much faster than you used to is a different sign — that is often sediment filling the bottom of the tank, which a flush may fix.

    How much to flush a water heater?

    A tank water heater flush and descaling is $375.

    Valley water is hard, so scale builds in the bottom of the tank. Popping or rumbling while it heats is the usual sign.
