This was an exact replacement for the old one that lasted about 10 years. ua-cam.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Best instructional video for water heater drain. Good detailed instruction.
A most excellent video covering so many areas correctly! Highlights the many minor details that make or break this process. Great job
This video may be 20 years old but still the best one on UA-cam on properly draining your water heater.
I agree
Video is only 7 years old.
Wow! Thanks for a very complete instructional video- without trying to sell me anything! You gave some great tips too. I now have the confidence to flush my tank without [typically] screwing up and then having to call the plumber!
This was clear and concise. Very informative and easily followed. Thank you very much
I have a plugged drain valve on my 9 year old tank. Many thanks for your video as it was very well done. I also installed a 3/4" ball valve as you mentioned.
thanks for the best "how to drain water heater tank "...VIDEO
Good video. Hit on all the important topics. Thanks for uploading!
Best video I've seen on this.
much better than the other videos. Very informative. Thank you.
Best video to explain how to drain and flush
Hmmm, never knew about deteriorated dip tubes. Thanks for that! I’ll check with my manufacturer to see what I have.
My tank dates from ‘03, has the ball valve drain you wisely suggest and, since I don’t have a convenient hose bib out front, the system is flushed every time I wash the car. I also have a pressure washer I use off the water heater and installed an in-line filter to protect the PW’s delicate innards.
Anode (what was left) was replaced last year (pneumatic impact wrench!) and I believe I’ll put that on a regular schedule (3 years? They are not expensive).
Another issue with accumulated debris on tank bottom is the insulating effect of the material. As you observed, efficiency drops as precipitate accumulates and heat that should be going into the water instead causes the bottom of the tank to rapidly oxidize, with ultimate failure not too far ahead. This condition can become so serious that bubbles of water vapor form in the debris and their release causes a popping sound when the heater is firing. A bad sign 😰.
Thanks again!
Thank you for the video!!
Your water heater was full of it. Nice video short and full of info.
you make it looks easy 👍👍
No mention of opening the pressure relief valve when draining and filling the tank?
Thank you for posting, excellent instructional video
Great video and explanation. Super.
Best video I've seen
Excellent! Very well done!!
MANY MANY THANKS for this video. Just followed your instructions and got the job done. Easy! Thank you !!!
Well done video. Thanks for sharing the tip.
Excellent video!
Great help. Thank you.
Thanks, very helpful!
Great tips & explanations! What about the problem of sulfur-eating bacteria in some areas that create hydrogen sulfide gas in your hot water? Advice for temperature settings (hot is better than warm?), and flush more often if home is vacant for more than 2 weeks?
Use ALUMINUM Anode Rods
Good work
Question here please. My 50 gallon tank has 8 year warranty, I'm on the 9th year. I've never drained it until now. I agitated the bottom many times and finally got the tank to run clear. Problem is inside hot water is still off colour. I live in Vancouver, BC for location. Every plumber says I need a new tank. Is there more I can do?
You are the best!!! Thanks
I flushed my water heater last year in June. Going to do it again this June.
It's my first house, and haven't lived here long.
When I flushed, the water very dark brown from the rust. Took awhile, but it finally started flowing clear. I'm sure the previous homeowner never flushed it.
The water heater still heats water fine and gives us good supply. But since there was all that brown rust water, should I start looking at replacing the water heater?
Yes you should
Excelente
I had to open the Pressure Relief Valve for tank to empty; opening a single hot water faucet created no flow. After doing some research, tank will not drain unless opened, hot water faucet is higher than the top of the water heater.
Wow!
This was very informative!
Ron, instead of opening a hot water tap on a higher floor, why not just open the relief valve on the tank? I live in Texas where (believe it or not) builders put water heaters in the attic (there are no taps on a higher level).
You can open a hot water tap anywhere, you just want to break the vacuum. If you fuss with the pressure relief valve I would suggest having a replacement on hand because sometimes an accumulation of sediment around the valve or a problem with the seal won't allow it to close completely and it may need to be replaced.
I had a Bradford White water heater installed in 2011. I had not ever drained it in fear I would mess something up.
I took on the project 10.08.19 and it was easy.
I’m glad I drained it but there wasn’t anything to speak of in the bucket.
We live in Dallas, TX. Could it be possible I need to check something else?
Thanks for your instructions!
great info!
Wow so much sediment
Great content, thank you!
I have a good quality Pura prefilter for all water coming into our home. If I change out that filter once a year, won't that cut down
on having to flush my tank? Meaning....won't that filter pick up most of the crud like I see coming out of yours (you had alot of big chunks inside there)? Every time I change my filter I find very little anything stuck in the filter itself. Just wondering what you think....
I had to take the drain valve out as shown. Should I be concerned about water or sediment getting between the insulation and metal exterior? Or is this no big deal?
Many thanks for your video
It was very well done.
Thanks, very clear instructions
Came to learn how to drain a water heater to fix a leak higher up and now I know about sediment and faulty dip tubes.
Thanks. How old of a heater was that and how often is drain and flush suggested?
I know this is a few years old, but do I have to turn the water off outside. Ive been draining my wh and its been a few hours and still not done draining
Did not ever think of doing this. One problem, My water heater is in the attack and there are no hot water valves higher than the water heater. What should I do?
Jeffrey, the best option actually would be to open the pressure relief valve to break the vacuum. I would use that over an open faucet anyway, so you can test its effectiveness. If that goes bad, your water heater can explode. Cheers!
You can replace the anode rod while you're doing all that too.
Thank you!
great vid!X Thank you
You make an awesome video.
Right
Did you to turn off water coming to tank.
Would you have sediment if you have a water softener?
Dude! Haze is the shit!
Mr. Hazelton: BTW the hot water faucet opened earlier stays on throughout the process? Or, does it have to be turned off once flushing begins?
I'll answer my own question. How about closing faucet once tank is drained.
I left it on for the entire process. I closed it finally after I was refilling the heater. Worked fine that way.
You just want a hot water faucet or two open when you turn water back on, and once everything is functioning and water supply valves are open, then you can turn the taps back off like normal. It’s a pressure thing, it can be hard on them if you don’t.
No need to open the pressure relief valve?
I have asked this question on several youtube tutorials . I see you open the faucet in the house in the beginning, then you open it again later !! At what point did you close it ?
You turn the hot water side of the faucet on to help with draining (air in line). You can close it when the tank is done draining or possibly when you're done flushing altogether.
lepke1979 .....yes. Your response is correct and I believe it is what the man in the video intended to communicate. However the video editing regarding illustration of this point is indeed, incorrect and therefore confusing.
Was flushing without turning water supply off twice a year and no sediment was coming. Tried with turning off water supply after switched knob to pilot, let water flow from a hot water tap that above water heater and flushed, still no sediments, just few particles. Am I doing something wrong or my water heater (Rheem with glass interior) is an exception :) My furnace humidifier (old drum style) building some particles over time so I assume water is not pure. I have not touched to anode bar as well. Any insight?
If theres no sediment, that's good. It just depends on the water quality where you live.
Any inhibitors or anti corrosive tablets needed?
Koolie Aid there is a metal rod in the tank sacerfacil Zink belive corrode instead of ur tank u can replace them to
Can you show me how to replace a water heater or furnace
its an electric one?
what steps do i take after water heater is drained?
anyone know how
You should have changed the pipe connecting the dip tube to the shutoff.
My water its look orange But only in master bedroom second flor in tup
That s probably the raison why all my hot water faucet washers are busting out .
The fact is that very little of the actual sediment drains out. I consider it a complete waste of time. The design of the bottom of the tank make it difficult for the sediment to drain

While you at it, you should have replaced the corroded pipe.

Is it safe to hang clothes over anhot water heater
I wouldn’t. I keep a wide berth from the furnace and water heaters. If the water to it is ever off (and your city could do it in an emergency or while working on it nearby and not tell you) and the heater itself is still on, it gets extremely hot at the top very fast. You can sear your skin on it like a branding iron so... not advisable.
Can I leave water heater on when flushing tank?
WMT MAN Power no , open hot water faucet in house and purge air before turning back on . You actually may have to leave water on at first to blow sediment out of drain faucet . some plastic drain valves may stop up with sediment and not drain at all , what's worse is they may drip and not cut off and what is worse plastic drain valve may twist off in tank if you try to change it out . Then you will have water running out of WH . I am in middle Tennessee and find very little sediment in gas WHs but a lot of sediment in electric WHs.

Just leave it on Pilot mode
I had no hot water from any faucet. I did the reverse flush, put a dime in the shower head. now the hot water heater won't light....why?
A flush is just to remove sediment, if you had no hot water, if electric either the breaker has been tripped or the heating element(s) are burned out. If Natural Gas, likely the Thermocouple has quit working. This acts as a safety allowing your pilot light to stay lit. When the thermocouple which is being heated by pilot light quits working the pilot light goes out and the gas valve won't open , no flame , no heat.
Geez, change the copper feed pipe . Very corroded
Please answer information pertaining to your video instructions that aren't in the video.
I've seen many "drain water heater" videos, but this one is the worst case scenario video I seen where the video show everything breaking apart and every water inlet in house had huge pieces of plastic everywhere..........I agree you should drain your water heater but this video maybe a "scare tactic" video where it show worst case scenario.
suggestion, generally only need to release 3-10 gallons- the pump sounds like a clusterfuck - always open water line slowly-
lara sounds like you know about "clusterfuck" well.
!
You have to have a lot of heart to tear apart your water heater like that.
What's your point?
WTF did you attach to the ball valve, did you solder it,glue it put spit on it Fuck me

I don’t have a gas water tank. Mine’s electric.
I was just told by 2 plumbers in Memphis ; you do not need to drain the water heater. These guys charge $180.00 for a few minutes job, cleaning the vent as it was exposed....turning off the water line to the heater and when I freak out, I have no hot water, they blame me for turning it off which I did not. I asked for a lower fee since they never turned a hot water faucet to see if it worked. I put the bill on my Capitalone credit card which intimidated them as they agreed I could still pay $180 but I will get a check for $30. Needless to say, if if do not get it, I am putting their names for all people to see. They have a reputation but I think it is unjustified. Wasted hours of my time, dealing with the problems of their lack of professionalism. Paying more is no guarantee you will get better service ! who says otherwise ? My vent was clogged up and disconnected and it took them minutes to clean it.
There’s literally no reason to do this. There still about 3 inches of water that can’t be drained
Best instructional video for water heater drain.
Great detailed instructions
