Could you give us an idea of how old your AS is, and your previous use of the fresh water tank drain? With a new-ish trailer , it is unlikely IMO that you have any build-up of organic sludge, unless something like leaves etc. got in when you filled the tank previously.
Some debris from construction might be blocking your drain, just inside the tank? Is this the first time you have had this problem, or perhaps the first time you have used the tank and drain?
Earlier threads discuss the drain, for instance:
and ROBERT CROSS has shown a replacement option in metal in Post #5 therein.
Removal of the plastic drain may be a little dicey IMO, as access to the hose clamp is tight apparently, and there is very little play in the length of the tubing to the actual tank.
I would consider holding a compressed air nozzle over the discharge, held loosely by hand, and blowing air back up the drain, to see if the rate of discharge temporarily increases. You might be able to push possible debris away from the back of the drain.
PS -- Ditto to earlier comment about drain possibly not being open all the way. Ours needs to be turned 180 and point to the rear of the trailer, to be fully open.
