Equalize black and grey tanks
Over the years I always seem to fill the grey tank first and the black is only 1/4 full Why couldn't you add a valve at the hose discharge and pull both grey and black tank valves to equalize the tanks. Water seeks it own level and gravity should do it. I f you opened the black slightly and let the gray in you shouldn't get black in the gray. And if you do so what you drain the black first anyway and just flush the gray tank...What do you think ???
