Richard has posted on this one before.  A side note on the PS air operated dump valve; In addition to the dump switch in the AQH bay another dump switch is located in the cockpit overhead panel (wink wink).  On our coach that dump valve had not been used in a while and was frozen shut   At least two occasions, I could have used the PS dump valve in a state park that had a dual lane dump station.  We had to wait on other campers, all the while the left dump lane was wide open.  Needless to say I made a concerted effort to get that valve working.  All in all I have to say Newell really thought about giving an owner some options with the waste tank.
