"Necessity is the mother of invention," they say. They also say, "Build a better mousetrap." Well, I just stumbled upon a rather clever new shower head. Thought that whole market was done like a burnt T-bone steak, did you? So did I but... not yet, it seems.

The name of it is the It Just Makes Sense shower head. That whole low-flow shower head thing has been flogged like a dead horse, and like low-flow toilets, they leave a lot to be desired. So, Fred Rahaming took on the hot water conservation challenge in a different direction. Full blast hot water when you want it, just a trickle when you don't.

Conservation and rampant self-indulgence, all at the same time. Can't beat it with a stick!

It works kind of like those camp showers; just pull on the chain when you want hot water. In this case, the chain is hooked to a spring so that you can quickly disconnect it with one hand to keep the flow going. And it's DIY friendly; I installed it in five minutes flat.
