| Feb 18, 2012 at 23:32 | comment | added | jontyc | Nice addition Sam, could have stood as an answer. You've got me know thinking to put the hot water tank up at 140F and remove piping insulation so I don't get scalded :) | |
| Feb 18, 2012 at 18:30 | comment | added | Sam Ley | Good answer - just wanted to add a detail. Legionella is the dude normally associated with hot water heater disease. They are fully killed above 140F, and have trouble living above 120F. If you have people in the home who would be particularly susceptible to disease, you should set your tank closer to 140F (though that increases the danger of scalding). Legionella spreads when people turn their heaters way down (under 115F) for efficiency (a better way is to get a more efficient unit and insulate piping). | |

| Feb 18, 2012 at 6:01 | comment | added | Caleb | Whether copper pipes are soldered or crimped depends on location, age and type of construction, and probably the plumber doing the work. For example, in my area there's very little new construction, and there's probably not a crimped pipe to be found for miles. New work in old houses, at least in my area, is usually soldered. | |
| Feb 18, 2012 at 2:22 | comment | added | yossarian | Worth adding that older pipes can have lead solder, hence the old advice about not using hot water for cooking. But if the plies aren't old, it's perfectly safe. | |
