Plumbing Water Stream Issue?
Hot water line to the vanity sink running very slowly. As well, the galley sink's water lines run very, very slowly. I flushed the water system after completely draining with a couple gallons of v...

What is a PEX? Do you have a picture of such?
The bleach has a dissolving of mineral and sediment ability. I could use an acid, but the bleach will also have a sanitizing effect.
If it's PEX (cross-linked polyethylene), you will find red (hot) and blue (cold) piping. Can't mistake it.
If you have an older RV, depending on age, it would likely be grey polybutylene.
Polybutylene is prone to many problems and some have opted to replace it entirely. PEX is pretty much indestructible unless you cut or melt it. It even has a memory if you severely bend it.
FWIW, we have a well at home and the lines have a little sediment in them. I originally installed some clear PEX near the pressure tank and incoming line and can see deposits on the walls inside the PEX. In 8+ years, sediment has never caused a problem of any kind. We have a 5 micron sediment filter (after the above). We have a lot of calcium in our water and it clogs up aerators, nothing else including piping. A couple of times a year we soak the aerators in CLR. Calcium can build up inside a hot water tank in the form of flakes. Had a HWT full of it in a previous house and had to replace the tank.
PEX is pretty inert and doesn't really attract "stuff" that will stick to it and build up. Don't know about PB though.
IMO, I doubt you have anything clogging the lines, esp. if only one faucet is affected. If you do find it's sediment, a filter will prevent future problems. Nothing you can do about calcium tho.
