A typical home water heater can provide between xxx and 60 gallons of clean drinking water during a disaster. Hurricanes, floods, earthquakes, and other power outages may prevent you from having many things, only make clean drinking water should not be one of them. To reclaim some clean drinking water from you water heater, and to tap your inner MacGyver, this is what you'll need to do.

1. ane

   Turn off the electricity or gas to the water heater. Plough off the circuit breaker for electric h2o heaters or close the gas valve for natural gas and propane types. If the power is still on when the tank is empty, your tank will almost certainly sustain significant damage. Most electric water heaters in residential applications are 208/240 volts, and supplied past a double-pole excursion breaker or two fuses rated at 30 amps.^[1]

   • Some gas valves have a thermostatic control knob facing frontwards. The "Off - Airplane pilot - On" gas supply knob is located on the top, between the carmine interlock push button the blackness "push-push button" ignitor. Simply rotate the top knob from the "On" to the "Off" position to stop the flow of gas to the burner.
   • Some electric-reliant heaters accept double-pole 30 amp circuit breakers. Switch the excursion billow from the "On" position to the "Off." One time off, there is no danger of dissentious the heating elements.

2. ii

   Preserve the cleanliness of the water in the tank by closing the supply valve to the tank. When h2o service is restored, the water department will be pumping water that could be contaminated. This will exist fine to utilize for flushing toilets and for cooking, simply not for drinking.^[2]

   • Determine whether you're dealing with a ball valve or a gate valve. Different a traditional gate valve's handle, which needs to be turned completely several times in order to shut off, a ball valve handle is rotated simply a ane/4 turn between full on and off positions.
   • If older, traditional gate valves were installed instead, bear in mind that the color of the handle does not guarantee an association with the temperature of the water in the pipe.

   Detect the valve at the bottom of the tank for draining. This is where your clean drinking water will come up from. Many water heater valves have a connector for hooking up a garden hose to the drain valve. A brusque iii pes (0.9 m) length of garden hose will make the collection of the water easier. A washing motorcar's supply hose is the perfect length and is available in many homes. Connect the hose and open up the valve briefly to flush whatsoever debris that may have collected in the valve. Make sure the drain, hose, and container are make clean before using them.^[three]

   • Threads are ordinarily provided to connect an ordinary garden hose (or washer supply hose). Some gate valves do non have a traditional handle, but rather a slot at the terminate of the stem where a handle would normally attach. The slot allows for operation with a screwdriver, or coin. Work this valve gently, as these valves are seldom used more than once or twice per year under normal service conditions, and could exist damaged if forced.

   Plough on the hot water from any tap in the house. In guild for water to be tuckered from the tank, you must permit air to go into information technology. This is easy to do past opening any hot water tap in the building such every bit the kitchen or bathroom sink. When either faucet is open, a sucking sound may be heard whenever water is fatigued from the water heater's drain valve, and is normal.^[4]

5. 5

   Remove any sediment that has collected at the bottom of the h2o heater. Water heaters are notorious for trapping sediments. The heavier-than-water sediment sinks and collects at the bottom of the tank because hot water is fatigued from the top of the tank, rather than the bottom. If you have sediment in the drinking water let it stand for a period of time to allow it settle to the lesser of container.

   • Typical mineral sediment that has settled in the hot water is normally harmless, just if your heater has an aluminum anode, at that place may be a lot of jelly-like aluminum corrosion past-production on the tank lesser.
   • Many people mistakenly believe that the tank is made of glass (or another inert substance). It is not. The inside of the tank will probable be lined with glass to forestall corrosion, since corrosion is the leading cause of h2o heater failure. There is no danger cooking or consuming h2o that has been contained in a h2o heater.

1. 1

   Although water from a water heater is considered safe to potable, consider purifying or filtering information technology before drinking. Although information technology's probably fine to drink water from the heater during an emergency, it's best to be on the safe side.^[5] You can purify water by boiling it or using iodine or bleach in very small quantities. Yous tin filter water in an emergency by layering filtering agents on pinnacle of each other.

2. 2

   Seriously consider replacing the original valve on the water heater with a ball-valve bleed assembly. Manufacturing plant valves practise not have a direct path and have minor orifices. In hard-water areas, those tin easily clog with sediment buildup and so no water will flow from the tank.

3. 3

   In an emergency, consider other options for beverage water. If you can't, for any reason, admission your h2o heater in an emergency, don't panic. You should accept plenty of other options. Consider these to get at potable water:^[6]

   • Possible indoor sources of water:
     • Liquid from canned fruit and vegetables
     • Water from the toilet tank (non the toilet bowl), unless it has been chemically treated with toilet cleaners
     • Water from melted water ice cubes
   • Possible outdoor sources of h2o:
     • Water from a rainwater collection arrangement.
     • Water from rivers, steams, springs, and other moving bodies of h2o
     • H2o from ponds, dams, and lakes

• It is a good idea to affluent some water from the bottom of the tank once or twice a year. Sediment can collect on the bottom of the tank. Draining some water under pressure will clean out the sediment.

• Earlier disaster hits, mark which valve is for the water supply. Run some hot water from whatsoever sink. Go back to the hot h2o tank and feel the ii pipes attached to it. The supply line will be the colder one. Somehow mark the valve as "supply". This will be the i to close in an emergency so that contaminated water will not become into the tank as y'all drain the make clean drinking h2o that is stored in it.

• A "tankless" water heater will non provide this source of drinking h2o. Tankless systems provide heated water from a coiled pipage located in a furnace. Water that is passed through the coiled pipe is rapidly heated and available for immediate use. There is no storage of the heated h2o - hence the term "tankless".

• Always have at least several gallons of drinking water on hand. Increase this amount in apprehension of severe weather. Replace water that has been stored for more than a year or and then with clean, fresh water.

• Allow the tank to fill before restoring power to the water heater. Open up the supply valve and wait for the water to run out of the open up hot water faucet.

• Plough off the power supply to the tank showtime. Fifty-fifty if there is a power failure you lot must unplug, turn off the circuit breaker, or close the gas valve commencement.

• Be sure that the water has had fourth dimension to cool before opening any valves on the water heater!

• If you live in an apartment contact the management first.

• Be sure the water within the water heater is not soft water. It tin contain backlog sodium (the harder your h2o supply is, the more sodium is used to soften it), which is not recommended for those with sure wellness concerns (such as loftier blood pressure level, cardiovascular or kidney disease). If you don't have a h2o softener...you're adept to use the water inside the heater like normal!

Things You'll Need

• Flashlight to detect the excursion breaker, plug, and valves if it is nighttime
• A short water hose to drain the water from the tank. The supply hose for a washing machine is perfect.
• A screwdriver or coin, to operate the drainage valve
• A shallow pan that fits under the valve to collect the water in. If you have a short hose you can use cooking pots, clean bucket, empty plastic gallon jugs, & h2o bottles.
