LOML called me at the office this morning to say that the water heater is leaking. She said it is a very slow drip and the pan with a drain is easily keeping up with it. Unfortunately we've got commitments which will keep us both busy until Sat.

Does anyone have experience with leaking water heaters? Is this something that I've got to replace ASAP or can it wait 3 days? My choices are pay $300 for installation today/tomorrow, or install it myself Sat morning, or install it myself tonight starting at 9 PM. What would you do? BTW, the water heater is in the attic over the second floor so a complete failure would be terrible.
