We have a 2017 Axis 25.5. The 3" black water PVC pipe from the holding tank separated from the dump valve assembly, while dumping last week. One hell of a stinky mess!
I'm trying to repair it. I got the dump valve assembly removed but now I'm not sure how to reattach the black water pipe to it. I see no evidence of any PVC glue either in the 3" opening of the dump valve hub or on the pipe from the black water holding tank. Is this just a compression fit? Seems to me that this joint should be cemented, because there's quite a bit of pressure on this joint and valve assembly when you're dumping a full 30+ gallon holding tank. Or, did the masterminds at Thor, who assembled our Axis, forget to add cement? The dump valve assembly we have is a double rotating valve with 3" hub inlet for black water and a 1 1/2" hub inlet for gray water. I do plan to call Thor Customer Care with this question but they are closed today, so thought I'd ask some of the experts here. Thanks!
