Gray Water Drainage
Our Gray Water doesn't dump very well. We have to drive back and forth to "shake" it out to get it to empty completely. Is there anything (vinegar??) that we could safely pour down the drain to help...

Check you AAV under the sink. It may be stuck closed and not allowing air to go into the tank to replace the water that's going out.

That would mean roof vent is blocked
AAVs are downstream of sink/shower 'P traps so that when dumping grey tank 'P' traps don't get sucked dry
A non opening AAV would not slow/stop grey tank from draining properly.
OP........
Has grey tank always been a problem draining or is this issue new?
