1. Turn off the electricity or gas to your water heater. 2. Turn off the cold water supply to the tank. 3. Attach a water hose the valve on the bottom of the tank. 4. Open the hot water valve on any faucet. 5. Open the valve on the water heater. 6. When the tank empties close the valve on the water heater, turn on the cold water supply, and let the tank fill about 1/4 of the way full to loosen any sediments on the bottom of the tank. 7. Turn the cold water supply off and open up the valve on the water heater to drain the rest of the water. If you have large amounts of sediment in your tank you may need to repent steps 6-7. If at any point sediment clogs the valve or the hose turn on the cold water supply to "blow' the clog out. Also remember when the tank is draining there is no water pressure so the tank will drain slowly.

Can you drain a leaking hot water heater by running hot water in home?

No, you have to attach a garden hose to the fitting at the bottom of the tank. Often the tank will have sediment built up in it and the water will drain very slowly from this.


Why brown water drains from hot water heater?

Brown-tinted water appearing when the drain faucet on a water tank is opened is normal. The brownish water is created by dissolved mineral and metal sediment collecting at the bottom of the hot water tank. This sediment creation is a normal function of the hot water heater heating the water and is released when you open up (or drain) the tank. Draining the tank should be done on a periodic basis - I drain my hot water tank every 6 months. Draining lessens the mineral/sediment buildup and helps extend the life of your hot-water heater.


Why is hot water sometimes rusty and brown?

It means the inside of your Hot Water Tank is starting to rust. If it is an electric tank, shut the power off and the water feed and open the drain at the bottom to drain the tank. Open the hot side of faucets in the house to drain all the hot water. When all the water is drained, close the faucets opened, close the drain, fill up the hot water tank. Go upstairs, unscrew the aerators and slowly open the hot side of faucets to drain the air until you have full flow of water. When all air is purged from the system it is ONLY then that you should turn the breaker for the HWT back on. If the air is not purged and the tank is not completely filled with water, you risk burning out the elements. For a gas tank, shut the gas off and do the same as above except for the electrical. Then fire up the gas after.

Even when house water turned off why will water still drain from the hot water tank?

Reason for question: Plumber left valve open and flooded house The hot water (heater) tank is fed from a 'header tank'; normally in the loft space but can be combined with the main heater tank (fortic). The header is filled from the water main. Unless the header is drained or its outlet is closed off, it will drain down through the open valve of the hot water (heater) tank.

how can I fix the hot water problem without an plumber?

According to DIY on Hot Water Promblems if theres not enough water then you hit the reset button. If the water is too hot then change the temperature and reset. If you have a leaky heater then you need to replace the valve. If you have a rusty tank then you need to replace the water heater. If you have a noisy heater then you need to drain and flush the tank. If you have dirty water then drain and flush the tank and do it on a regular basis.

Can you shut off the cold water intake to hot water tank to stop a leak not in hot water tank?

Yes, but there still is all the water stored in the tank plus the water stored in the existing hot water lines throughout your home that will eventually leak out.If you intend to install a hot water heater (HWH) yourself and you do not have valves to isolate the existing plumbing then turn off your main water supply, drain the water from your home using the lowest level sink, then attach a hose to the bottom of the HWH and drain the tank. When you install the new HWH install new shutoff valves. (Hint: Check with your local city plumbing and see if an expansion tank is required.)

How do you bleed hot water tank?

There is a safe and slow way to do it, by turning off the water to the heater and removing both vacuum breakers and then opening the drain valve to the hot water heater. You can now drain it, which can take about one hour. However, depending on where the hot water heater is positioned, lets assume above a bath or outside installation, you can turn the hot water off and open the flange on the face of the geyser and drain it in about one minute.

How do you flush out a hot water tank?

Attach a garden hose to the drain spigot and run the hose outside or into a toilet or sink. Open the spigot and drain the tank until the water runs clear. You could have turned off the water heater beforehand so as to reduce the risk of scalding yourself. You should drain the tank as recommended by the manufacturer. If not, lime scale forms and insulates the bottom of the tank and causes the water heater to use more energy because it cannot heat the water efficiently.
