The drain cock on this water heater is there for a reason! This owner sucked 6 gallons of -50F antifreeze into his 6 gallon water heater & system without bypassing the water heater......!


Freeze, split, cha-ching $$$$$$$$$$$$$$$$$$$ !!!


DO NOT DILUTE YOUR PROPYLENE GLYCOL!!!


It would take far more than 6 gallons of antifreeze, in a 6 gallon water heater, to get zero dilution.


If you don't know how to winterize you had better know how to write checks.... D'oh!!
