hot water stopped running, need new ater heater?

I bought a house, initially I turned on the water and power and the water heater seemed to work, came out of all faucets in house, then a few weeks later it stopped running when you open a hot water faucet. I then noticed a little bit of water below and around the bottom of the heater cant find where the leak is coming from.

Possible causes? should I just get a new hot water heater?

Some causes of opening a hot faucet and nothing comes out:

THe valve at the cold inlet to the water heater was turned off or sediment from the main water supply clogged it.

The pipes have lime deposits after decades of use, reducing the diameter of open space through which water can flow and some sediment finished clogging the opening.

So much sediment has accumulated in the bottom of the water heater tank that it blocks the cold water from entering via the dip tube.

The tank having rusted out and sprung a leak is probably not the cause of no hot water at all coming out of the faucets.


States can help recovery from hurricanes and tornadoes by not requiring due digence or prompt and timely correction of substandard conditions, and by providing continued liability insurance where companies drop homeowners.

Thanks Allan for the reply, it sounds like it could be the sediment clogging something, the house was built in 1954.

A couple other points, the water heater is from 2006, the house was vacant for almost a year before I purchased it.

Might there be an easy solution or would you suggest a plumber?

Is this a gas heater? The water you see may be condensation. 4 yrs is a pretty short life span.
As far as no hot water flow, check inside the hw nipple at the top of the tank. There is usually a rubber assembly inside it. Or perhaps a ball check. Make sure that is not pluged with sediment.
