Design Flaw in Fresh Water Pickup Line New Trailer

Thanks Soundguy. I actually had to bring my trailer to the RV service center for another issue, so tacked this one on. Just got my trailer back, to my surprise they didn't remove the underbelly cover, they just punched a hole thru it and left the fresh water pickup on the outside of the underbelly and used a tee (on the outside of the underbelly) to connect thru the punch hole to the drain. Looks like I might have to fix the fix.

Thanks a lot for your insight.
