<strong>Yahoo Message Number: 80271</strong>I've dumped a few times in the past 6 years!!! Every few dumps I flush the black tank. Today I realized I always flush using a pressure regulator. Maybe I'm a bit slow!!!! <br/>Question - Should you flush with or without the pressure regulator on the hose? Can the system handle 'full' pressure?<br/><br/>Thanks.<br/><br/>Bruce<br/><br/>2001 Intrigue #11278
