I have a 2021 16' deluxe Scamp.  Everything works perfectly, except that I am getting sediment in my water from somewhere. It clogs  the faucet aerators.  There is no sediment in the water tank.  The source might be the hot water tank.
In the photo below, you can see that the tube on the left has significant sediment in it. The tube on the right has a little bit of sediment.  I cannot tell where the tube on the left goes.  If I knew that, I would be able to find the source of the sediment.  Can anyone help me?

Thank you for any hints/thoughts you can give me.
