Fresh water drain hose plugged

[annie oakly]

How do I unplugged a the Fresh water hose, I have put water up it. it has cleared it a bit. but now has slowed down again.
Don't really want to rip the under belly apart of the trailer
Was thinking about getting a small wire bush and putting it up the tube and cleaning it that way.

Any idea why it's plugged? Insects? Recent problem?

Possible that it's debris inside from manufacturing, plastic shavings or similar blocking the tank hole?

I'd try pushing a piece of smaller diamter plastic tubing , cut on an angle into the tank, hopefully its a straight shot into the tank.

If it is crud and not plastic solids you might use a shop vac to suck it out. Can you see your tank under something. If it is plastic trash from installation you may have to cut a hole in the top and reach in to pull it out.

Or just let it drain slowly.

Are you sure the restriction is in the hose and not the check valve where you connect your hose? ~CA

Hi That was the first thing I checked ( I put a new one as the other one was going to break. Here is a picture of the water line and the water tube that I can put of the line
Came out dirty that why I think a line wire bush may help

Maybe push a piece of weed eater line up in it from the outside and see if it breaks anything loose?

I have had hard water make a lime build up in the lines. Use compressed air to blow it back and clear the line.

I replaced that valve on my rig with a 1/4 turn bass valve with a hose fitting on it. My crumbled from age and also I can now put a hose on it to route the water away from my concrete slab.

Not sure why they put such small drain valves on these
