Gas Water Heater : fix or replace ?


Hi guys,

Just discovered this forum, wonderful !

I bought a new house this year and now I have a problem with the gas water heater.

It is 12 years old.
Brand : GSW 40 Gallons

Since a few weeks, there was a few times I did not get hot water.
To fix it I usually do:
a) go in the basement and play with the temperature dial so I hear a sound to force something
b) wait a few minutes/hours

Hot water always comes back.
But each time I experience the "no more hot water" problem, I always see a little spot of water that leaked from the tank.

Do you recommand fixing it or replacing it since it is already 12 years old ?

If you recommand a replacement, which brand do you suggest ?

I'm near Montreal, Quebec, Canada.

Thank you.

Time to replace it. I'm sure one of the plumbers will be along to suggest a brand name.

Does you water heater have electronic ignition? Where is this spot of water? It's probably time to replace it, but I have had water heaters last 20 years+...but not those with electronic ignition.

12 years old, replace it.

As an aside: My parents moved into a house in 1957 that had an existing 40 gallon GE electric water heater. My father and I moved the WH from the kitchen to the basement. I sold that house (with the same WH) after my parents death in 1997. That WH was in excess of 40 years old. They don't make em like they used to!

It is not electronic ignition.
If it stops, I have to light it manually.

Water leak comes from the safety valve (I think) and go straight down to the empty valve then in the bottom of the tank.

I'm calling tomorrow but the "best" place in town seems expensive. (I mean the company that installed it and the gas furnace 12 years ago)

Approximately 1500$ +tx
1075$ for the water heater (I think it's a JohnWoods)
+ labor
+ parts if necessary
Did I forgot to say taxes too !?

Each new tankful of water expands a little when heated. If there is no expansion tank above the water heater (or if the expansion tank is waterlogged) the temperature/pressure relief safety valve may trip.

It is not unusual for the kick on temperature for the water heater control to be erratic and the tank not heat up when the temperature of the stored water has gone well below normal. This is the problem if the first person to take a shower has turn the dial up a notch or two (and wait 20 minutes) to get hot water but immediately turning the dial back to where it was leaves the heater running for the 20 minutes.

I'm not sure I understand exactly what you mean but I might add that it seems to happens when we use "less" hot water.

For example, when we went to Florida for a week, we returned and there was no more hot water and some water on the floor that leaked from below the water heater.
