hot water tank problem


Just went downstairs in my basement to find a good size puddle under my hotwater tank. I just recently put a bucket under what I want to say is the drain pipe coming out of the side of my tank to the floor. It has a pressure release value on it and a 3/4 pipe that extense to the floor(dont knot the tech. name for it sorry) but anyways lived in the house for year and a half now and never had this issue before. Just checked the bucket and found a little water in it. The drain pipe drips every now and then that I can see. Just wanted to know the reason for this and do I have a problem with my tank and if so what can i do to fix it.
thanks

This is either caused by a faulty TPR (Temp/Pressure relief valve). The valve is faulty or the water is overheating.

Turn on the hot water and measure the temp if it is over 120 deg check the setting on the water heater to make sure that it hasn't been turned up. If the water is 120 the replace the TPR.

You should be able to find one at a plumbing store or a Blowes/Home depot

I know for a fact that no one has touched the temp on the hotwater tank. Its just me and my wife and she would never go near the thing. The valve can just go like that? It seems like the valve is never really used unless I am mistaken which is probaly the case but I will check the temp. and if its right i will change the valve thanks

Yes a valve can just go bad from the expansion and contraction with the heating/cooling of the water

with the bucket under the drain off pipe from the relief lift the silver arm and blow off some of the water thru it...then empty the bucket and see if your still dripping after an overnight

Sometimes they can have a funny moment and drip but like the poster above says just release some pressure from the tank via the Pressure release valve and it may be fine. 90% of the time this happens that will fix the issue. If not then it's a simple fix to replace the valve.
