239ML Black tank flush connection leak

[Fireguy24]

When I hook up my hose to my black tank flush on the outside of my trailer water shoots out of the fitting that goes into the rear of my black tank, underneath.

Welcome to the forum
Sounds like the rinser is either clogged or the fitting has failed. Is the hose crimped or is there a fitting that screws onto the rinser?

It may not be the same for you but I have had to replace two fittings that were fractured and the only way you could see the crack was to take them off and shine a light inside the fitting .in both cases the cracked one was black and the replacements were gray and look like they are made a lot sturdy. One the dealer replaced and the next one I did.

It looks like it is some type of screw in fitting on the side of the tank near the top of the frame

If the hose is attached with a screw on type of fitting, odds are it’s either loose, or cracked.

I know this is a silly/stupid question - but - did you put a hose washer in the fitting? Our Laredo came to us without hose washers. Dealer must have needed them for another trailer - or the techs were selling them on e-bay.
