Voltage is like water pressure in a pipe

I'm replacing every outlet and switch in my house for two reasons, one, they are almond and I want white and second, because several of them were in this kind of condition:



This is the outlet that my fridge was plugged into. Its the worst one I've had. Two others looked okay, but disintegrated in my hand as soon as I pulled them out, and then there was the dryer outlet that almost caught on fire.

Here's a tip for all you house flippers out there, free of charge. Spend the extra buck fitty to replace any broken outlets. Heck, spend 20 and replace them ALL.
