Small Puddle Under Hot Water Heater – Problem?

I have noticed a small puddle under our hot water heater lately. If I look underneath the heater it looks like its coming down from only one leg. We have sold the house and just had the inspection last week and passed. Could it be from the inspection testing? Condensation? If it is a leak in the tank how do I know and can a plumber detect a leak in the tank or do they always suggest a replacement? Want a cheap solution because moving expenses are eating into cash reserves.

    It could be your pressure valve. Press the handle and if it squirts, then that is where your leak could be coming from. Usually it is something as simple as a rubber rings inside that has worn. It depends upon how old your cylinder is. They should be maintained regularly and serviced every 6 to 8 years.

    Just leave it alone. If you press the pressure valve some times they don’t stop leaking. Maybe after the house inspection that is what happened. After a few days it should reseal itself and stop.

    If the house passed inspection and the papers are signed, LEAVE IT, the new owners are responsible. Hot water heaters go bad, it’s just a fact of life.
    If the tank is leaking then there is no way to fix the problem short of replacing the tank.
    Depending on the size of the tank, if it’s electric or gas. And if you can put it in yourself, (it’s not hard) You could have a small chunk of change wrapped up in it. maybe as much as 300 to 700 dollars.
