sharing gray tanks
Seems like we fill one tank before the other is 1/3 full. Anyway to share the tow as one tank?

All three of my waste tanks dump via one common drain line.
I installed another drain valve on horizontal run just before elbow where line turns outward.
With it closed I can equalize both grey tanks (galley would always fill faster than grey) giving me 78 gallons of grey tank capacity.
After dumping black tank I can close added valve then open grey valves and flush grey water into black tank for a flush.
With added valve closed I can equalize ALL three tanks and have 128 gallons of waste tank capacity. (Wasn't that long ago RVs only had 1 tank)
A 'twist on' valve is available but it would stick out too far on my 5vr and would need to be taken off/stored for travel.........permanent install was cheap and easy.
The 'twist on' style could be used with rigs that have 2 dump lines and a 'Y' connection.
