Cool

If by "top pipe" you mean the temperature and pressure (T&P)relief valve (looks like this):

T&P VALVE
then you need to replace it, if it has started leaking.
(The white corrosion is from minerals in the water.)
1. Turn the gas or power to the heater OFF at the breaker.
2. Attach a water hose to the drain spigot at the bottom of the heater.
3. Close the cold water supply valve to the cold water inlet pipe to the top of the heater, or turn the main water shutoff valve off, if there isn't one to the heater.
4. Open a nearby hot water faucet for air, and the drain spigot, and allow some of the water (and the water pressure) to drain down.
5. Remove the old T&P valve.
6. Wrap 2-3 flat turns of teflon tape clockwise only on the threads of the new T&P valve. Tighten it in with a pipe wrench.
7. Turn the water back on to the heater. Let a hot tub faucet run until the air is out of the heater and line, and there is a steady flow of water.
8. Turn the gas or power back on to the heater.
Voila!
Good Luck!

Question reply to old gut

Dear Mr. Old Guy, Thanks for the reply. If you are looking at the water heater the tpv valve is on top center-to the right is a blue turn on handle witha a pipe--this is where the leak is- I hope I made it clear where its at. Is this a bad leak? Thanks Vivian

Vivian:

The T&P valve is not on top of the heater. It is on the side near the top and has a pipe going down to about 6 inches off the floor and not connected to anything.

It sounds like your leak is at the supply valve.

Is it leaking where the valve is soldered to the pipe or where the handle goes into the valve? If it's leaking at the handle, you can tighten down the big nut under it, and it should stop. If it's leaking at the pipe, you'll probably have to replace the valve.
