How do I correct this problem?

First, if that is a pressure recucer it is not a good one, get a Watts and put it between the park and the hose.

Now.. a common problem is the hose washer, they get old and hard and need to be replaced.. They still LOOK good, but alas, they are not.

Thank you all for your responses.
I moved the reducer to the other end.

It must be the fitting. Not dripping from the hose fitting into the water "port", but what I see, either behind the petcock, or the seam at the bottom.

I had a similar drip in my wet panel. They replaced the valve. The extended warranty paid for it, along with a few other things that almost paid back the cost of the warranty. Almost.
The calcium/lime build up should not cause any problems, other than being unsightly.
IMO, pipe tape or pipe dope should never be used on a self sealing fitting such as flare fittings, compression fittings, or hose fittings (there is a washer or 0-ring in there that is supposed to seal). Pipe tape or dope is for tapered pipe threads only.
But, hey, if you have used it and it worked for you, it is your rig and you are entitled to do things your way.
Personally, I prefer to do it right instead of over.

Interesting Arch.

Hadn't thought of that issue. But I follow 'cool' so I'm seldom in a place where that might happen. Good advice in hotter temps.

I would argue against the advice of putting the pressure regulator at the shore side of the hose.

When the sun hits the hose during the day tremendous pressure can be built up as the hot water expands.

My reducer is right where Jaybird's is and that's where it's staying.

I've had a hose burst and so when we leave the campground I always turn the campground water off.

I figure if the pressure is great enough to blow up a hose I'd rather the hose blow than my interior plumbing.

Thanks Jim!

Lime is calcium hydroxide, other common scale is calicum carbonate. Both will be removed by CLR.

Ah, those petcocks are drains. And off would be the proper position. Looks to me from the photo that each valve has leaked from behind that panel. Based on the rust patterns. So I'd remove the panels and see what's up behind there. Probably just need to tighten things up back there.

thank you ALL!
I will move the reducer and see if that makes a difference. To me it looks like the drip is behind the petcock. Is there a hose that could be broken behind it?

P.S. are the petcocks in the proper position for shore water?
