Black water flush leak

[Jbryson]

Black water flush opened and all seemed fine. Then some clean water started coming out from under camper. Called dealer they said a valve or hose loose probably and needs adjusting. Dealer is a good three hours away and wanted to try to diy. Any suggestions? Had anyone else had this problem? Also, there was no backup into bathroom anywhere. Just clean water coming out from under camper between the flush tubes and the under plastic. Thank you!

On our rig, there is a convenience center, where among other connections, is the fitting that goes to the black tank, via an airgap valve. From the airgap, the line goes to the opposite end of the black tank from the drain valve end. there should be no fittings between the airgap and the point at the end of the tank where the flush device is located. This is a photo of where our flush line terminates at the front of the black tank. This fitting may be where your water leak is at.

There is basically two pieces of hose between your garden hose connection and attachment to the tank. Hose 1 between garden hose connection and the anti siphon valve generally under sink in bathroom. Second hose from other side of the valve directly to connection on the black tank. Not leaking in bathroom which leaves only one more connection and that is to the tank. I would bet that is where leak is (hose to connector on tank)

Problem will be how easy it is to get to it. I try to avoid cutting that under belly, although some members do not hesitate to cut an access tab to reach the area.

Had the same scenario a while back. Mine was loose at the water hose connection. Had to pull an interior panel off to get to it to tighten it up.
