Check all the sockets, light fixtures and switch panels throughout the house to be sure they are wired properly. If at any point the walls start breathing, finish up as quickly but as calmly as possible and move on to a new task. That is a good indication the house is getting curious about you and may try to take your skin off.
Plumbing and Water Heaters
Now that you've gotten familiar with the house, you'll know which rooms are what we'll call "water rooms." In a multi-story house they will generally be stacked on top of one another and they will include every room with a faucet. Both hot and cold water lines will run to each of these and you'll want to test the warm water for a few seconds to be sure the water heater is functioning properly. If it never warms or produces something other than water, such as pain, then you have a lot of work ahead of you. It means the water heater is either broken or missing and you'll have to go to the basement to be sure. Warning: This will surely be one of the hardest, most excruciating things you will ever have to endure, not just in home renovation but in life. Good luck!
Once in the basement, locate the water heater as quickly as possible. Examine the tank for leaks caused by corrosion. Check that gas is flowing to the water heater and that the pilot light is still lit. Though rarely, sometimes the heating mechanism itself can fail which means you'll have to replace the entire water heater. To remove it, you'll need to turn the gas valve off, disconnect the drain valve and unscrew the locknuts on the inlet and outlet pipes. If as you work you hear a voice whispering that your soul is forfeit, stop, wait a few minutes and try again.
"I will taste your bones."
The last step is to pull the flue free from the gas heater. You will feel a rush of air followed by a cold and panicked human hand forcing its way inside your mouth This is completely normal. As you pass out, do your best to protect your head from nearby objects and also double check that the gas is, in fact, off. The last thing you need is a gas leak!
When you wake up, check your chest and limbs for carvings in Latin. Refer to the glossary at the end of this book to determine what message has been scored into your flesh. Read quickly though because you will now be faced with the physical manifestation or your worst fear. Do you see it? If so, good. You'll have to fight it. To stand a chance, abandon all thoughts of love or attachment to life. Open your mind to vast potentials of torture, and unadulterated misery. A longing for pain and despair is the only way to defeat a terror this infinite. Kill. Kill and hurt as though they were your eternal purpose, strike with both your body and also your soul.
It will change you permanently.
Almost done! With your fear lying before you in a bloody pulp, it is now safe to remove the old water heater from the basement (you may want to enlist the help of a friend to avoid hurting your back). New water heaters are available at most appliance stores and you'll also want to pick up a temperature/ pressure release valve to prevent explosions if the heater ever fails again. They are relatively inexpensive and a great investment.
