Just finished our shakedown trip on a new-to-us 2024 13' Standard
Scamp (we're the 2nd owners); our visual pre-purchase inspection was fine but it's tough to see every little thing.
Went by the dump station at the end or our trip. Hooked up the hose, noting that the bayonet hose port faced to the rear of the trailer, as opposed to side of the
Scamp like the grey tank port does. When I opened the black water valve, the entire ABS elbow, slide valve, bayonet fitting and slinky hose fell off the trailer, and thus baptised my arms in black water. Joy!
It looked as if the elbow had never been securely attached to the
fiberglass stub end that terminates just flush with the bottom of the trailer subfloor. It's not clear to me whether this was to have been a glued connection.
Upon closer inspection at home, it seems the elbow itself was a repair job due to a crack, possibly from some impact. It seemed to be a pretty solid repair though. Nothing that would have caused the joint to fail. As far as I can tell some wax from the toilet ring was used to coat the inside of the hub connection on the elbow before pressing it up onto the
fiberglass stub, but no other adhesive or sealant appears to have been used. As opposed to the grey tank piping, the black piping was not supported with any pipe hangar strap.
Some questions:
- is the ABS piping intended to be glued to the
fiberglass? I can see why it would be preferred *not* to glue this joint, so as to allow removal of the assembly for future repairs
- if glued what adhesive to use?
- if no what is normally used to support the ABS pipe assembly (vertical elbow, slide valve, horizontal elbow, + bayonet fitting)?
If nothing else, I propose to re-apply some wax to the upper elbow, firmlyu slide it back into place, and install some hangar strapping to carry the
weight of the assembly. Does that sound right?
