Water pooling above Coroplast

Heavy rain every day in Florida.
FR Sierra 377FLIK 5th wheel.
See that water is pooling on Coroplast which is drooping because of weight.
I am trying to figure out if rain water is finding it's way onto Coroplast or if I have a leak in plumbing.
Has anyone had this issue on their's?
No leaks inside.

More likely to be a leak in the plumbing somewhere. It could be somewhere that you can't see. I literally just fixed a leak on Saturday. It's in my basement/deadspace area behind a partition that you never have a reason to take down. Turns out this has likely been leaking for months if not longer based on the amount of damp wood I'm seeing.

I'm gonna bet it's a plumbing leak too. It's pretty difficult for a roof leak to present itself there if it's not inside the RV.

I can say we had a shower drain vibrate loose and cause a similar problem once.

Yes, it has been raining in Florida.

Do not know how your Coroplast is attached, but I do recall an old post that had same problem, As I recall the Coroplast extended past the rear edge of the Rv and rain water was running just the right direction to run on to the Coroplast.

drill a 1/4" hole at the lowest spot and let the water out. Then watch it when it stops raining.

I just found the leak.
They ran the flexible water line for the ice maker.through the metal cross braces underneath.
Looks like sharp metal edges nicked the water line.
I should be able to splice out the leak.
Has anyone used the PEX tubing crimpers?
Is it obvious once you buy the tool?
I need to join solid blue PEX tubing to braided flexible line.

For transitions like that, I just use the regular screw hose clamps.

I replaced plastic union with metal and tightened screw hose clamps down tight.
All good now.
Installers routed braided hose thru metal crossbraced and sharp edges nicked hose.
I re-routed to prevent future repeat.

Nice Work on your part


"Installers" being a relative term.
We are thinking about upgrading from a Dutchman. Alas, bad workmanship follows........Ughhh

Pex tools aren't hard to use, but if you don't have a set already and don't foresee a great need for them, you could try a shark bite fitting if that will work on both pipes. They basically just press on and can be removed using an open end wrench as a press on the end. They're a little pricey, but a good option if you don't want to deal with getting pex tools.

You can get a tool and a few lex clamps on Amazon for $25 or so. Easy to use.
