My gas hot water heater is leaking at the top where the pipe comes out of the hot water heater and goes into the house. It is leaking at the connection point where the pipe would screw into the hot water heater. There is quite a bit of corrosion around that section. I can feel down at the bottom that the insulation inside the tank is wet and there is a small (but growing) puddle on my garage floor. Is there an easy fix to this? What about the wet insulation? I have an AHS home warranty that expires in 2 days, I called them and a plumber will be calling me tomorrow morning. Is there anything I can do between now and then to fix or minimize the damage?
