My wife and I are not young any more and have to contemplate our mortality. My wife has been bugging me for a while to document how to do some things around the house, such as how to turn the water or gas off in case of an emergency. One other issue was how to flush the tankless water heaters.
So I put together a number of web pages the document each item, going step-by-step so that she could follow the directions if I wasn't there. Most of the items are specific to our property but I thought the one on flushing the tankless water heater might be of interest to others. The web page is here.
In case you're not familiar with tankless water heaters, they require annual flushing with a weak acid (vinegar) to remove any build up of mineral deposits on the tubing in the heater. It's not difficult to do, and it's important to efficient operation and long life.
