Question about Rheem 40 Gallon FVR NATGAS Low WATER HEATER 6YR 22V40SF
The water heater makes a bubbling sound. There is sediment on the bottom of the tank. How do we drain it and get rid of the sediment?
You can try to flush the sediment with the water and power on. Just hook a short hose to the drain and shoot it into a clean white bucket (so you can see what comes out). The drains on most water heaters are far too constricted to flush anything but the small particles, so if your problem continues you might consider replacing the factory drain with a short 3/4" dielectric pipe nipple, a 3/4" full port ball valve, a 3/4" m.i.p. x 3/4" garden hose male and a garden hose cap with hose washer. That will give you some serious flushing capability.
If all of these steps won't get rid of your noises take comfort in the fact that the noise may be a nuisance to you, but it is not doing any really bad damage to your heater. I also strongly recommend getting a water softener to prevent this problem from ever happening again.

Install waterhose to the draindown valve at the bottom, turn off the supply valve at the top, either break the cold supply line or flit the lever of the temperature and pressure valve ( to break the vacuum ) If it is electric, turn off the breaker, if it is gas turn the red knob on the bottom to the off position. Let all the water drain. Open the cold water supply valve and let it run for around 15 to 30 minutes.
Close the T&P valve ( or tighten the supply line ) Open a hot water fixture ( I would use the tub ) When water starts flowing from the tub faucet with no air, turn on the electricity or gas valve. This should be don once a year.

I've faced this with a number of hot water heaters, both gas and electric. It is possible to get rid of the sediment buildup. The replacement of the factory drain will help some, however, it may not get all because some buildup settles back down in the water faster than the water could move it around to drain out. The drain doesn't reach all the way down to the bottom of the tank, but rather an inch or 2 above the bottom.
One solution depends on how much work you're willing to do, or pay someone to do. You'll need access into the tank for a tool you'll have to rig up. For electric water heaters, remove the lower heating element. The tool: Take any larger size shop-vac that sucks water, using adapters and/or ducttape, attach a flexible rubber hose to the shop vac. This hose must be small enough to fit into the element hole. It also needs to have the largest inner diameter you can get. For the most part, the sediment is not powder but mostly chunks - some the size of small marbles, some the size of golf balls, some the size of BB's. All of which is easily crushed and comes apart when pressed on. Using the shop vac /rubber hose combo tool, insert the hose into the element hole and vacuum away moving it around inside as you go. You'll need to expect this to take some time. It's slow. Large chunks can be crushed using the hose or using a pole or rod that fits inside to crush it. You may not be able to get 100% of it, but with patience, you can get about 85% - 90% I'm estimating, and enough to have the water heater working well again.
To get 100%, you would need to remove the water heater to outside, and allow for it to lay down, again using the vacuum hose, and working away at it until you get all of it. Expect it take time. Possibly over an hour or two working away at it. (It depends on how much work you're willing to do, or how much money you're willing to pay someone else.)
For gas water heaters, there is no element hole (a large hole), you'll have to get a smaller hose meaning that the vacuum process will be even slower. Check your heater to see what the hold size is. Remember, the hose has to easily fit inside the pipe hole and be able to be moved around inside and out. To make the job "easier", again remove it to outside, and turn it on it's side or better - upside down using the holes at the top of the water heater and vacuuming from underneath.
It takes time but it can be done, and has been done by others.
