Most of the things I've had to replace on the rig have come from parts supply stores attatched to a regular RV dealer. I have yet to really deal with a DT dealer yet for this as well. The "other brands" are stocked with the same kind of stuff. I just replaced the water fitting for the black tank flush where the hose attatches as well as the back flow preventer valve and got them both off of the shelf at a dealer that has other brands like Jayco. They were not specific to DT and are both working fine. Go in the dealers store and if it looks like a mini campers world they probably have what you need. I look for ones that have a good selection of hardware rather than the picnic type supplies that cw has on display.
