Strange noises from a water heater

<< < (2/6) > >>

MonMotha:
To be fair, the Mythbusters had to defeat several safety mechanisms to make that happen on a modern unit...

shmokes:
Hmm, it's in a rental, so i doubt he'll go through all that.  At least it sounds like it's not dangerous.

Ours has been doing that for a long time. I call it our popcorn machine. I'm sure it is not good for the bottom as it gets heated probably more than it should. (Ours is gas) You may want to be careful if you try and drain it some. I have heard of it clogging the drain valve and they won't close all the way after that. Then it drips for a while. Same thing with testing the relief valve. Things can get caught. Usually fairly easy to get those unclogged though. If not, either part is not very expensive. I believe you can drain the water on a gas unit and then take the drain valve off and put a wire hanger in there to loosen it some. Then try the wet vac. It should get more out but you have to be careful not to put a hole in the bottom.

I have a new one. I just need to put it in. :P One of these days...

How old? Companies that rent water heaters will replace them for free when they are around 12 or 13 years old.

Hoopz:
I just replaced my water heater last year.  We had a great deal of buildup in our old unit and I would drain it at least once a year.  The issue I had though was that the sediment pieces were too large to drain out.  I couldn't get my shop vac hose in the unit because the drain hole was too small and the hole where the element goes in was much higher than where the sediment was.  I could some out of the element hole but not a lot. 

The key really is draining it on a regular basis so that the calcium buildup is flushed out before it gets too big or too much.
