You posted under water heaters.
Always let a water heater cool off before draining.
Hot water can cause serious burns. Immediately put burned area into cool water.

There are different types of water heaters, and each might drain and flush differently.
Open following link for typical gas and electric tank-type:
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flush

To drain and flush tankless, it can be called de-liming tankless.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime
Be sure to read tankless manual for instructions and advisories, and required maintenance.

If you have boiler, or indirect water heater, solar water heater, or RV heater, the instructions above may not apply. be very careful with a boiler due to extreme high temperatures.

How do I drain the water tank


Anon, Make sure gas or breaker(power) is turned off to the Heater so it will not come on during draining,connect a hose onto bottom valve of water heater, run hose to a floor drain and insert, turn your water main off so as not to fill tank while draining, open water heater drain valve, water will then drain from attached hose into floor drain until empty. For water to run faster you may open a near by hot water tap, this will allow air into tank as you drain it, do not forget to turn this tap off before refilling tank. You then can turn main back on for a bit if you would like to do a flush of sediment from the bottom of tank.

SOUND LIKE YOU NEED TO DRAIN AND FLUSH YOUR WATER HEATER TANK. THERE IS A HOSE BIB AT THE BOTTOM OF THE TANK. RUN A HOSE FROM IT TO A DRAIN OR OUTSIDE. SHUT OFF THE COLD WATER INLET VALVE AND OPEN THE HOSE BIB. OPEN HOT FIXTURES IN THE HOUSE.CHECK THE DRAINING WATER FOR CLARITY. IF CLEAR OPEN THE INLET VALVE AND LET IT FLUSH(YOU MAY GET MORE DISCOLORED WATER, RUN UNTIL CLEAR). SHUT HOT WATER FIXTURES, CLOSE THE HOSE BIB AND LET TANK REFILL.

How to clean a water heater


turn off breaker to heater if it is electric, turn off gas if not. turn off water supply to heater. Hook up hose to bottom drain (if one is not all ready piped to outdoors). Open water drain valve at bottom then open any hot water side of the faucet. Tank should drain down, taking some of the buildup with it. Once drained, close faucet that was opened, turn water supply back on and flush out remaining deposits. It may be neccesary to replace the anode rod from the top of the heater if you have excessive build up.

I need to flush my Atwood L/P Gas water heater MPD 93756 I'm unable to locate where you add the vinegar. Can you advise!


Remove hot pipe connection, and flush out through drain valve.
Or remove TP valve and flush out through drain valve.
Connect small circulating pump to 5 gallon bucket with 2 gallons white vinegar like they do with tankless water heater, as shown following Bosch manual. And let run for 45 minutes.
http://waterheatertimer.org/pdf/Bosch_Descaling-heat-exchanger.pdf
White vinegar is safe for humans.

If odor is the problem, use H2O2 hydrogen peroxide, and not bleach. Hydrogen peroxide is safe for humans and easy to flush out of water heater and pipes. While it can take weeks to get rid of bleach, which is caustic and toxic.

Our hot water will last for about 5- 10 minutes then turn luke warm. I have replaced both elements but problem remains . Do you hink it is the thermostat ? thanks chazz


If you have not done so already then turn thermostats up to 140 degrees. You may also try to drain and flush tank to clean out any mineral deposits that could be hurting your effiency. To do this shut off electrical power to heater then connect garden hose to drain valve on the bottom of tank. Run hose to floor drain or other safe area and open drain valve. If it drains good with the water on then let it flush for a couple of mins. then shut incoming water supply off. Let tank drain as far as it will. You may need to open a faucet on the hot side of nearby fixture to break vacumn.
Drain it completly then close drain valve and hot side of faucet.Turn water supply back on and let tank refill. Do this 2-3 times to get inside of tank as clean as possible. Hope this helps you and thanks. P.S. You may need to replace thermostat also.
