I have a question that bothers me every morning. I wake up and go to the john
to have a shave and turn on the hot water full blast. Over the next 20-30
seconds the water temperature goes from freezing to quite hot as desired. 
The problem is that the flow rate of the water drops off as the temp goes up. 
If I don't touch the faucet the flow nearly stops. What is happening? 
I assume it has something to do with the expansion/contraction of the pipes 
in response to the temp. Any good plumbers out there?
One more thing, the pipes start to scream as the water gets hotter but if
I increase the flow by turning the knob the noise disappears.
