Maybe so - but I'm the #1 maintainer of my mom's and sister's water supplies, so for instance I know to buy new hoses in 2015 for their washer. Giving them my old hoses is only meant to address sudden leaks or a 3am gusher. they'll hold for a few days until I stop by and get them new hoses.

I'm not figuring to draw water from my heater but you never know - I have over 360 gallons stored in 3 places around my home and property, if I need water from the heater at least I know it will have been recently flushed. Cedar River watershed water is notorious for its lack of sediment though.
