Re: Flush an old hot water heater? Regardless, I don't understand why manufacturers don't get rid of dip tubes and use "bottom entry" tanks. |

said by Bob:In Canada, the water heaters have the cold inlet at the bottom of the tank (on the side). No dip tube. That makes so much sense to me, I don't know why we don't see that type here.
Could it be because they are easier to replace if the bottom feed pipe doesn't have to be moved out of the way to get a new heater into position?
Could be just "the way it is" but I'd be interested if anybody can give a historical perspective.
Regarding the copper conductor used to bond hot and cold pipes, it's a good idea even if those pipes are not relied upon for ground. With few exceptions, every pipe in the house should be grounded to ensure it does not become HOT.

Having slept/showered at the house for a few days, I can now say that the reason for the water heater being turned up so high is because the dip-tube is more than likely broken. The hot water is fine for the first 5 minutes or so, and then starts to get cold quickly.
I checked the bottom of the tank above the burner and there isn't too much rust down there. Some spotting but nothing to make me think it's about to leak. I'll try to replace the tube sometime in the coming weeks, and might as well replace the anode while I'm at it. |

| I thought that the dip tube might be broken in our current place, as we had the same 5-miute window to take a shower. Once I took a look at the water heater, I found that the hot and cold connections were reversed. Once I fixed that I could take a hot shower for 30 minutes. 
The previous owners bought the house new and lived with it like this for years!  |
