<strong>Yahoo Message Number: 95191</strong> To flush out the RV antifreeze I read in the manual that the water heater should be shut off so as to not run all the new water completely through it. Is this important to do and is there a bypass switch on the water heater to shut off before proceding?<br/><br/>Diane, Dave's widow<br/><br/>aka Billy Byte (trusty hound) <br/>2000 Allure #30443<br/><br/>
