Re: Hot Water Heater Recirculating?
Do you have a lot of sediment in your water? If so, it could be that the tank is full of dirt, and the capacity has been severely reduced.
Open the drain valve at the bottom. If nothing comes out, suspect the above... but poke a wire into the valve just to see if maybe there's just a chunk of something blocking it.
Water heaters should be flushed annually to remove sediment by opening the drain valve at the bottom.
The dip tube is easy to replace, sounds like you've got a lazy plumber. Remove the nipple on the cold side. If the dip tube's not attached, look inside the water heater, you may be able to pull it out of the inlet. If you still can't find it, it probably fell inside and you just need to get a new one from the hardware store.
