I have several rental properties in suburb of Dallas. As you know that these week we will be experiencing extreme cold weather down to single digit, which is very uncommon for Texas.
Aside from the regular preventive measures that I used to give to tenants, ie., wrapping up outdoor faucets, dripping kitchen faucets, turning on ice-maker, setting thermostat to at least 70F, keeping cabinet doors open, etc., I am also thinking of asking them to turn on dishwasher before they go to sleep, setting it to 4-hour-delay start. I hope this will induce more water flow during midnight.
Do you think that this is a good idea? Does this step pose unnecessary risk to the life of the appliance? Any input would be very much appreciated. Thank you.
