gray water tank - Wolf Creek 850
Hi guys Wondering how long it should take to drain our gray water tank (tank capacity = 19 gallons). For our black tank it takes about 2-3 minutes to drain but gray tank takes significantly longer...

I would suspect a tank cutout still in the tank.
This^^^^^
Grey tank drains are typically 1 1/2" dia. (even though they may connect to main 3" line)
So grey will take a bit longer just do to size of pipe BUT the flow should be basically the same until almost empty
When tanks are installed openings are cut into tank to connect vent/drain/dump lines.
Sometimes the cut-out discs fall inside tank and don't get removed.
The discs can float around until draining tank..then they can be pulled down to outlet and obstruct drain.
Stop draining....they float until next dump.
PITA the remove.
