During a disaster potable water is at a premium. Once domestic services start going out you can no longer turn on a tap and take a drink.
So how do you find hidden water in your home during an emergency?
Even when the water stops coming in, your pipes can still hold up to several gallons depending on the size of your home.
You will be able to access this water by turning on the lowest spigot in the house and letting the water gravity feed. Once this is gone you can sometimes open an upper spigot as well and that will release any water that may be vapor locked in the system.
If you still run out you can find the water inlet into your home and open it there (you may have to cut the pipe. If you do this turn off the inlet valve first. After this water is gone open the valve and see if any more will trickle in.
Unless you have gone the on demand water heater route your tanked heater will have between 40 and 80 gallons in it. You can access it by opening the drain valve at the bottom of the tank.
Most toilet tanks hold around a gallon of water in the back tank. This water is clean as it has not been in contact with the bowl.
If you live in a humid climate you may run a dehumidifier to keep humidity levels lower in your home. If it is the catch basin type you may have a supply of water if you haven’t dumped it lately. If you have the type with a drain pipe you can tap into this and see if there is any water.
If you happen to have power but not domestic water a dehumidifier will give you distilled water from the atmosphere.
In the winter many people run a humidifier. These are another source of water in your home. If you have the old style that has a fan the blows through a rotating cloth or mat you should purify the water before drinking since little beasties like to grow in dark wet environments.
If you live in a dry climate you may have a swamp cooler. Many swamp coolers work like a
humidifier that is run in the winter. They may have a reservoir of water.
Canned vegetables and even tuna (packed in water) have drinkable water in them. Most people just dump it down the drain but in a survival situation this stuff is life. It may be slightly high in sodium depending on what veggies you have but it is better than nothing.
The gallons of water available in a water bed are not good for drinking (but may be used for other things to save your drinking water). This water is treated with all kinds of chemicals to keep algae and bacteria from growing in it.
If all else fails you can collect rain water from your roof. It is best to filter it since you never know what those birds are doing to your roof while you aren’t looking.
As you can see there are many sources of water in almost every home. If you are smart and conserve what you have available you should be able to get through most disruptions to your domestic services.
If you want to always have a safe and clean supply of water, consider picking up a few WaterBricks. Each brick stores 3.5 gallons of water (or food or ammo!) and they are made to stack easily like Legos. Their easy grip handles also make them easy to grab n’ go in an emergency.
