Take a look at the supplies for the sinks, the DW, and the toilet. Tell me what you find.........

I know taking a shower when the DW or clothes washer was running was unwise. Re-plumbing changed that. And I don't know how the number of bedrooms would affect hot water use or flow. On the otherhand, I don't use 500 kwh a month of electricity to keep my hot water hot.
