Hot water heater

[sheila]

Hi, We replaced our H2O Tank about 4 yrs ago, on our 1992 Schult, It is leaking, we are in a Community (unfortunatley) and not on a basement or slab so it is leaking under the house. Is there a way to repair a tank? Or must it be replaced? If replaced can one be purchased at Home Depot or a similar store?
If anyone has any idea's what to check, or anything at all, please email me.

Thanks!
Sheila
