With out stating the obvious there will be water around the base of the hot water tank.

Simple Checks

If you discover a leak around the base area on your hot water tank we have to determine if its the water tank, water valve or from around the electric element area. There easy checks so lets get into it.

PTR Valve check

On the top third of a electric hot water heater there is a valve called pressure relief valve or ptr valve for short. There will be a copper tail on it. Follow the pipe to the end and see if any water is escaping from there. Now these valves are meant to leak at times when the water tank is heating the water so when checking the ptr valve make sure the tank is not heating creating a false reading. best way i do it is turn the heating source off and wait till it cools down and then check. If water is still leaking then have a faulty valve and needs replacing see here.

Electric Element Check On A Hot Water Storage Tank

Make sure power is off to the element from the fuse box area. Remove the 2 screws that hold the cover plate on and check around where the 4 big black bolt heads are. That is the element and sometimes the element gasket leaks but not very often. Most times if leaking from around this area the flange is rusted out and the whole tank needs replacing. You don’t have to go poking around in there you will tell as soon as you take cover off. If you see water leaking out around the element area when taken the cover off like in the picture.electric element

You can pull the element out if you are that way incline to see if it is the element seal of the tank. Depending on the age of the tank say if its getting around its use by date, rule of thumb 10 yrs or so and of course that all depends water quality it might be better to just replace the hot water storage tank all together.
