Making the following assumptions, how far away is the water heater location?
- The bathroom is plumbed with 1/2 CPVC pipe.
- When the faucet is turned on, and calling for hot water only, it takes 11 seconds to feel the first hint of warm water.
- The house water pressure is set to 80 psi.
So, how far away is the water heater? Explain your answer rationale, please, in the comments.
