Grey water leak

[1Longbow]

We have a 2014 Wind River 250RLSW,owned since new. We have a grey water leak,somewhere where the piping goes into the grey water tank. Before I go cutting the under belly,I thought I'd ask if anyone else had this problem,and where the plumbing attaches to the grey tank. If I pour a bucket of water into the sink,some water goes into the tank and some leaks and drips from the under belly. Connections are tight under the sink. I contacted Outdoors RV for a schematic of the plumbing system. Anyone else have a similar problem ? Thank you

I would test the galley sink, shower and bathroom sink individually to see which one is causing the leak.

If it leaks at all tests, then you most likely will have to drop the coroplast and check underneath for a loose or failed connection at the tank area.

Not very technical work, but a big pain to find and repair. Especially if you have to drop the tanks to fix it.

I would start cutting into the coroplast where the water is leaking out, and work your way from there. There is 2 layers of fiberglass batt insulation that will need to be removed if wet. If you follow the wet insulation it should lead you to the source. These enclosed spaces can be a nightmare when you get a leak.
