Begin by turning off the gas at the tank and at the valve near the tank. CAUTION: Do not proceed any further if you do not know how to relight the gas pilot!
2) Turn off the COLD water supply to the tank.
3) Attach a garden hose to the drain valve at the bottom of the tank. Run the hose to a convenient drain location. Be careful if you use a real cheapy garden hose... some of these become very soft when hot water runs through them, and may leak! If you don't have a drain in the basement floor or suitable sump hole, you have my sympathies... this drain-down can take a while with a bucket! Oh... and be careful if you use a soft plastic bucket. It can also soften from the heated water so don't overfill it or burn yourself!
4) Open up the hot water side of any faucet. Open up the drain valve on the tank and allow it to empty. Miller time. That is, unless you don't have a sump...
NOTE: If the drain valve clogs, turn on the cold water supply to the tank to use water pressure to "blast" through the clog.
5) When the tank is empty, shut off the drain valve and turn on the cold water. This will loosen up more sediment in the tank through the churning action of the cold water in the tank. Let the tank fill partially and drain it again. In fact, if you find that the sediment starts to clog the drain valve, turn on the cold water supply to the tank, which will help loosen the sediment and blast it out.
If you have extreme amounts of sediment, you may have to repeat this procedure a few more times. Look at the drain water... if it is running clear, you are done. Shut off the drain valve, open the cold water supply and allow the tank to fill. Once water comes out of the hot water faucet, the tank is full and your task is done! Now, you can turn the electricity or gas back on to heat the water.
How frequently to clean the sediment from your tank...
This depends on the source and purity of your water supply. Some pros recommend doing it annually, some every few years. I would recommend doing a partial drain down annually if you find any sediment in the tank, otherwise every couple of years.
Remember that with an electric water heater, you must turn the power off! Even a partial drain down may expose the upper heating element to the air and permanently damage it!

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.

Do you have to shut off pilot when draining a rheem hot water heater


No.
But if tank is empty for days, you don't want the water heater firing, since it will eventually affect the metal heat-transfer surface between water and flame.

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.


If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:
http://waterheatertimer.org/Emergency-steps-for-leaking-water-heater.html
http://waterheatertimer.org/Water-heater-is-leaking.html

Open following link if you want to install your own gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

I have a rheemglas standard electric 40 gallon water heater and the hot water in the shower or any where in the house only last 3 maybe 4 mins.....?


You should have two panels on the front of your water heater most likely painted blue. Each of these panels contains a heating element. The top panel contains the reset switch. Unscrew and remove the top panel and you'll see the reset switch - it is the red button. Press it to see if it clicks. If so, your hot water should last longer.

If it does not last longer than you stated, then you most likely have a bad heating element. The problem is that unless you remove both elements, you won't know which one is bad. If you don't feel comfortable turning off the water valve to the heater, turning off the power to your water heater at the circuit breaker box, draining the heater of it's water using a garden hose, removing the wires from the elements, removing the elements and installing new ones from your home improvement store then you may want to hire a plumber to do it.

The process is fairly easy but time consuming. The most time is draining the water heater. If you do choose to do it yourself, you will need to get a special "wrench" from your home improvement store to remove the heating elements first. The store can help you with the element(s) you need once you take them in.

Popping noise in water heater. What is it and how do I fix it?


What is probably happening is that you have a build up of minerals on inner tank lining and when unit is heat it expands the tank and the deoosits at a different rate which is what is causing the popping noise.
I would turn power off to your heater and hook a garden hose on to drain valve.Route hose to safe area as the water being drained will be hot. Open drain valve and see if you can get it draining good.If it is then shut off water supply to heater and open hot side of faucet nearby to prevent vacumn from slowing down draining. I would drain as much as I could then close drain valve and faucet and refill tank. I would do this several times to try to get all sediment flushed out.Hopefully this will help with your noise and make your heater last longer and work more effceiently. Good luck and thank you.

Both upper and lower heating elements are working and both thermostats have been changed but Im still having problems where my hot water doesnt last very long. Could my dip tube be my problem, and if so...


before going to far on this. drain water out of tank untill it runs clear. there may be a build up of sediment in the tank. try this first. shut off cold water to tank.
  • The cold water line should have a shut off valve on it. If it does, turn it off. If it doesn't, you may have to turn off the water at your regulator or at the street.

  • On the bottom of the water heater, there should be a hose bib. Attach your water hose to the bib and run the other end to a drainage site of your choosing. Open the hose bib and allow the water to drain out. when done flushing it turn on cold water and let sit for a while to build up the hot water.
  • If your water heater is gas fired, turn off the gas valve at the water heater locaton. If it is electric, turn off the breaker controlling the water heater. before draining. have a nice day !!

    Water heater heats water, but not long enough or sometimes not hot enough. The hot water runs out too fast, does not provide hot water continually


    The first thing I would do is turn up temp control on gas valve.Control is located on front of gas valve at the bottom front of heater.They usually have a indicator dial on front with an arrow pointing direction.Turn dial to higher setting when burner is not on and this should turn burner on and provide hotter water. The control is normally turned clockwise to increase temperature.If control is already turned all the way up then water heater may need to be replaced.Depending on water quality in your area heater may have a large amount of mineral build up and it may not be capable of producing enough or hot enough water. If this the case all I can suggest is to try to drain tank and flush some of the deposits out. If you have installation manual it will give you instructions on how to do this. If not see if you have working shut off valve on cold water line ,if it works shut it off and connect drain hose to drain valve on bottom right side of gas valve. Put hose to floor drain or sump basin if you have one. Turn control knob on top of gas valve from on to pilot,this will leave pilot light on but prevent burner from working while draining. Open drain valve ,flow rate may be slow or not at all. Open hot water side of some faucet to provide air to help draining. You may try opening water supply valve to heater a few times to aid in draining. If you can get it to drain,shut drain valve off when done,turn cold water supply back on and shut off hot water outlet. Then when tank is full open hot water vavle to bleed air out of heater and piping. Turn control knob on top of gas valve back to on position. This should bring burner back on .It will take about 1/2 hour to heat. If you can't get it to drain or this doesn't help you might consider getting a new 40 gallon heater. Hope this helps. Thanks

    Need to empty reliance 501 hot water heater how?


    1) Shut the breaker off to it at the panel. 2) Hook a hose up to it (the bottom has a drain). 3) Close the valve to the water heater (on the cold water supply). 4) Open drain on the bottom of water heater. 5) Open the relief valve to allow air into the tank (it won't drain otherwise - think if you put your finger on one end of a straw - the liquid stays in until you let go). Why are you draining it by the way?
