Say Hello to the Power-Pipe
So what does happen to hot water once it disappears down the drain? Water in most houses is heated for hours in big tanks just waiting for the opportunity to be used for a moment to clean dishes, clothes or our bodies. Isn't it a shame that all of that effort to heat and maintain the precise temperature of water is used so casually and then dumped into the sewer. Wasteful isn't…
