thats what I'm saying... i get the temp right before changing any water... it uses a bit more hot water but i have a huge hot water heater.... if your worried about sediment harming your water, you can use the drain valve to blow most of it out, also most water conditioners detoxify heavy metals anyhow...... then you don't have to run or risk the thing blowing apart and soaking your house.... however everyones water pressure is different so it depends on your ariea.....
