It appears the leaks are coming around the top half of the unit.
Try to isolate if leak is from incoming pressure side or discharge side. (Incoming pressure side) Might be simple fix to tighten loose connection of hot or cold at back of water valves. Sometimes access is more of a hassle than fixing.
If you're unlucky and you have a shower diverter pipe behind the wall or shower enclosure (instead of a hose at shower faucet to shower head) maybe a disgruntled employee put about 20 holes in it with a nail gun in the pipe when making it. Which water only leaks when diverter is in use and took 2 years for leak to show up. By that time warranty is over and dealer says "sorry not our problem". One reason why we only use water in self contain mode and never city water. And will never again buy a new RV off the lot.
