This muck is what is at the bottom of most water heaters!
Unless your have placed a filter on your hot water, you should never drink hot water directly from the tap or cook with it.
It would seem logical that using the hot water to cook with would speed up the cooking process, but it’s best to be safe and just not do it. Having your heater flushed regularly and keeping it well maintained is a must!
As always, give us a call and we will be happy to help!
