A 1 amp leak is unusual - and serious. That is 120 watts. If there is an actual 1 amp leak, most of that 120 watts of heat will probably be being generated in a small localized area - maybe carbonizing or burning up insulation somewhere.
A 1 amp leak through water will almost certainly cause some serious electrolytic corrosion.
If you find such an animal as a 1 amp leak, find where it is occurring, and repair it before you have a fire. I expect there to be damage and maybe smoke.
