Good water pressure throughout the trailer

[Greighard]

I have no water pressure to the upstairs toilet. shower and sink have great pressure. Is there something I am missing?

LOTS more information is needed to try to help.

1. What kind of trailer is this toilet in?

2. Is it a new problem that just started or has it never had water pressure?

3. What kind of toilet? Dometic or Thetford?

4. If the toilet was winterized? Is there a "dimple" on the back of the water valve that's connected to the water supply coming through the floor? That dimple would indicate internal freeze damage.
