Patti - Once you get your valve issue settled, I'll offer you an option I read here last year and it requires 4 valves to work.
Gray Tank 1/Bathroom (50 gallons), Gray Tank 2/Galley (30 gallons) - you fill up one and you've got to dump it or quit using water. Regarding the 4 valves (Final, Black, Gray1, Gray2) - Always, Always, Always make sure the Black tank valve is CLOSED until you're ready to dump it. Now that we're sure it's closed, make sure the final (typically add-on) valve is closed. This is the valve that keeps you from getting funky water on your hands when you pull the cap off to drain stuff. Now that both the Black and Final valves are closed, open BOTH gray valves. They will effectively "share" the space between them and allow for more use before you dump.
Now if you're running full hookups at a campsite, this is all null and void (except Black). If you're dry camping, your only limitation is your fresh water tank or whatever water you bring with you. Keep in mind that 1 gallon of water = 8lbs. So 80 gallons = 640lbs of water you lug around until you dump it. I think at the end of the day, this option allows you a little more time before having to dump the gray tanks.
