    Default Water Heater Drain Valve Modification

    My water heater (LP GAS) drain valve configuration has been modified. The valve was removed and extended out a few inches with a copper pipe. In addition, a T was inserted in line with the extended drain valve. The third port of this T appears to feed hot water to other locations in the house. So, I appear to have two hot water connections to the water heater. I have never seen this done. Can anyone explain why someone would have expended the extra effort to do this? What benefits are there to this configuration? I am quite sure that sediment is finding its way to the faucets that this connection feeds.

    It's probably a hot water return line.Usually (but not always) there is also a small pump installed in the line. The idea is to circulate hot water through the hot water piping so that you don't have to wait for the water to heat up at the tap.
