Water Leaking From The Bottom If you notice water leaking from near the base of your water heater, it could be an issue with the drain valve. The drain valve is designed to empty the water tank when needed, such as during maintenance. Solution: Inspect the drain valve for corrosion and replace.
Water leaking from the bottom of the water heater unit is usually due to sediment buildup inside the tank. This sediment is generally caused by minerals in the water that settle at the base.
Corrosion
Water heaters are subject to constant exposure to water and sediment, which often builds up at the bottom of the water heater. Over time, this sediment can lead to rust or corrosion. Left unattended, this can cause leaking or flooding.
Open the drain valve and insert the wire into the tank. Move it around a bit in order to loosen any debris or sediment that may have formed around the drain. Back-Flush The Drain: the idea here is to use water to push sediment away from the drain valve so that your tank can drain freely.
Draining your water heater is the only way to remove accumulated sediment.
However, if sand-like material is still found or the water is discolored, turn on the cold water supply to allow more water to fill the tank. Once it is partially filled, drain again. Repeat the process until the water is clear of sediment.
Using a wet vacuum can quickly suction out clogs, while a wire hanger or pipe cleaner helps dislodge stubborn debris within the drain line. For less severe blockages, a natural solution of baking soda and vinegar can dissolve buildup when left to sit before flushing with water.
Your Condensate Drain May Be Clogged
The most common reason for water under your furnace is a clogged condensation drain.
Once you've located the leak, you'll proceed with the next steps: turning off the water, and the heater itself, before draining the tank and ultimately fixing the leak or calling a plumber.
Call the Experts! It's no secret that a leaking water heater is an emergency, but you also shouldn't turn a blind eye to visible damage on the tank, strange noises, and a complete lack of hot water.

WHAT HAPPENS IF I DON'T FLUSH MY WATER HEATER? Leaving sediment build up in your water heater can not only cause it to work harder, but also lead to some serious problems like corrosion, clogged valves, or leaks.
Near the bottom of the tank, locate the tank's drain valve and attach a standard garden hose to the valve. Be aware that some models may have a cover over the valve opening. Place the other end of the hose in a floor drain or on a driveway where it can drain safely.
Water heaters show several signs of going bad, including lack of hot water, temperature fluctuations, decreased water pressure, strange noises, rotten egg smell, visible leaks, rusty or discolored water, and increased energy bills. If your water heater is over 10 years old, it may be time to consider a replacement.
After you've drained your hot water tank, you can pour a gallon or so of vinegar through it. To ensure the tank gets a thorough soak (try for 6 hours), close the drain valve before introducing the vinegar. Before you restore power to the unit, flush all the vinegar out. Keep it at the right temperature.
Begin by closing the drain valve while connecting one end of a washing machine hose to the valve and the other end to a water hose. Connect the water hose's other end to a threaded faucet; then turn it on while opening the drain valve for around 15 seconds. As the water flows, the clog should be undone!
Keep an eye out for debris suddenly showing up in your water. If you notice sediment or any brown sludge coming out of your faucet, that's probably an indication that it's time for a water heater flush. If you see any of these signs, it's a good indication that your water heater needs maintenance.
Typically, draining a 40-gallon water heater takes somewhere between 30 and 45 minutes. The overall time is heavily influenced by the size of the unit and the rate at which the water can exit the tank through the drain valve.
