In our Princeton model the entire kitchen sits on the front slideout. That, of course subjects electrical and plumbing lines to repeated flexing. It appeared that our sink drain hose had been failing long before we purchased the coach and several previous repair efforts were evident. After 12 years the hose had now deteriorated to the point where replacement made more sense than repair.
Unfortunately, Beaver put the junction between flexible hose and ABS pipe back under the corner cabinet in a location that could only be accessed by a child thin enough to slip between the cabinet front drawer frame. Fortunately, the ABS pipe is much more accessible under the center drawer stack so I decided to cut the pipe behind the drawers and bypass the entire hose run. There's plenty of room to feed the new hose around the corner under the OEM pipe and hose.
The last step of the process was to find a suitable hose. It's a 1-1/2 inch flexible hose with wire reinforcement. I've heard of other people using hot tub hose, but I found an exact replacement here:
http://www.amazon.com/dp/B000I1PL0U/ref=pe_175190_21431760_cs_sce_3p_dp_1 It's hose intended for decorative pond use. The hose I purchased appears to be significantly more rugged than the OEM hose. I used the entire 10 feet and created a loop inside the unused corner cabinet. I think this will reduce the "flexing" that results when the slide is closed since the coiled hose should slide over itself rather than bending.
Anyway my DW is pleased that we should now be able to dry out the corner cabinet area and eliminate the sewer gnats that had taken up residence there.
