There is a pipe coming out from the water heater. This pipe has a valve, but it was not sealed. Water is dripping from that pipe once in a while. Is that a leakage? What should we do for that?

That is the overflow pipe. It is necessary for that pipe to be open so that A, excess pressure can be relieved (this prevents water heater damage) and
B you will notice the water and have the condition corrected.
Some plumbing systems need the addition of a pressure relieve device called an "expansion tank". These are relatively inexpensive and quickly installed by your plumber.
Your plumbing contractor or local plumber can tell you if you need the tank or a TP relief valve. .

The pipe for is the pressure relief valve. It is a safety device to protect the tank from building up too much pressure and rupturing or bursting a pipe.you could try puling the lever on the valve but be care-full, hot water will come from the pipe make sure you don't get burnt. after letting a little water out of the valve close it some times this will make it stop leaking if not replace the valve with one from the hardware store there not too expensive.

You might not have a bad "overpressure valve"
What might be happening is your water heater is causing expansion in the water system causing high pressure. This might be due to a one way directional valve on your water meter. In other words, it lets NO WATER FLOW back ward. You can test this by simply adding a water gage anywhere in the hot system and see what it reads. If it reads like 90 PSI +, then you need an "air bladder tank" installed in the line to take care of expansion. Those are available at Lowes or the Depot.

without seeing it, i'd guess it's the overflow... when the pressure gets too high this opens and releases water...
this is usually located about 1/3 of the way down from the top of he water heater.
call a local plumber and explain what is going on and where it's coming from... if it is the overflow, they should tell you.. otherwise, get it checked to be sure, you don't want to have it flood the area its in.
