I think I read somewhere that its best NOT to keep you black tank open and running into the sewer all the time. Or did I read that wrong?
Look at it this way........
A fast flowing river can carry boulders downstream
A slow moving creek can barely move a pebble out if the way
Waste tank drain valve(s) always OPEN.....that's the same as that slow moving creek
Leaving Black tank drain open WILL result in the dreaded 'poop pryamid' which will take time/effort to get rid of.
Leaving Grey tank drain open CAN result in accumulation of food particles, sluffed off skin, grease/oils, soap scum etc. being left behind because that slow moving creek can't carry that stuff ot of tank.
And then there are the Sewer Flies.....they live/breed in sewer/septic line and WILL come up thru your sewer hose and set up house, have babies, invite their cousins to come live in your waste tanks
I don't bother hooking up sewer hose until I am going to dump (Full Tanks).....then dumped black--flush/rinse then dump grey
Flush FULL toilet bowl of water TWICE to add water back to bottom of tank so anything still in there doesn't stick/dry out and black tank is ready to use while in transit.
When to dump?
Toilet 'burps' when you flush
Sink/shower starts to drain slower
I haven't even looked at those 'gauges' in over 7 yrs.
