Hot water being wasted in the pipeReader submitted

Got under the house the other day, and saw that my plastic hot water pipes are running like spaghetti.  Sometimes the length of the pipe is double the distance from tap to hot water heater.  All the hot water that fills the pipe then just cools down when I turn off the tap. I'm heating the Auckland suburbs for free!

I reckon a quick re-plumb will halve the wastage, and halve the time I wait for the water to get hot.

Could lag that sucker too...
