Yesterday our 80 gallon water heater (less than 5 years old) ruptured - flooding our basement. Situated right next to the water heater is our sump - but it didn't do 1 ounce of its job, because it is sealed for radon remediation.

Any suggestions on how I can achieve both water drainage into a sump plus radon remediation?


Question: How do I increase sudo password remember timeout?
Answer: All information for sudoers can be found from the terminal with the command

man sudoers


You can even user simple text to edit files, however the privs make that difficult. 
sudoers is -r--r----- (Octal 0440)

This indicates that Apple really doesn't want you messing with the file. This really is the core security of the OS.

Options for editing are vi, emacs, or my personal favourite BBEdit.
