Also check that the fitting (swivel adapter) that attaches to the toilet is tight. They can loosen. They are designed to be finger tight, no tools.

Leak could be the swivel fitting, the cinch clamp connection (or maybe a crimp ring), vacuum breaker or water valve. A photo would likely help here.

Water is the no. 1 killer of RVs so gotta fix it pdq. You could always pull the toilet out and connect it to a hose outside. Need the right hose adapter fittings to do it. I did it once when replacing the water valve to ensure there was no leakage whatsoever.

Does it look like a recent leak or happening for a while? Does it look original or maybe modified by the PO? The water valves can sometimes leak only when water pressure gets low - around 10 psi and less.

So I put on my cheaters to try to get a better look, it's such a tight space to see behind, and realized that the leak was at the connection where the plastic pipe screws onto the back of the toilet. I unscrewed it and inspected the gasket. The gasket seemed fine so I screwed it back on tight and so far I haven't had any more dripping. I don't understand why water would be in the line all the way up to the toilet since my tanks are empty? I even tried to cycle the toilet flusher to release this water. Does this line have a one way valve or something similar that prevents the water from flowing backwards into the holding tank or is it the design of the water pump to hold the water after its pumped through it? As far as posting pictures goes I tried reading the how to section but it's all foreign to me. I'm using my cell phone to post here but can't figure out the deal with the public website thing or the copy and paste thing. I don't see any icon that would indicate posting a picture. Thank you all for your replies.

Our trailer new leaked from the "hand tighten" connection (one with typically 3 wing grip) at the toilet the first trip out. I hand tightened it, problem solved. A couple of trips later, much less water leaking behind the toilet. I finally figured out the vacuum breaker was leaking. ~$20 from Amazon and 20ish minutes of work and the vacuum breaker was replaced. No more toilet leaks. It has been used connected to city water and the onboard fresh water system. No more issues.

Thanks for the response pld33270! After tightening the connection I figured it was fixed. Two days ago I filled the holding tank with water and turned on the pump and it was leaking like crazy from the black piece right above the connection. Needless to say I'm waiting for a new water module to arrive today from Amazon. The previous owner winterized the TT but didn't realize water stayed in the supply line all the way up to the tank and it cracked over the winter. Here's a pic of where the crack is located.[image]
