Waste Tanks Slope

by Don and Tys 1999 U270 36 12/5/12

I've read in many threads where folks say they tilt their coach while dumping to enhance the outflow. I am wondering if that really helps much. Having had the opportunity to see the waste tank set up outside of the coach, it's clear that the tanks are designed with a built in slope to speed the dumping/flushing process. The wedge shape of the bottom of the tanks and the fiberglass platforms that they sit on also is what makes it possible to get the tanks in and out without cutting any waste pipes or vents.

It does make a lot of sense especially for ease of installation. You simply pull those wedges out from the curbside, the tanks can then drop down and be pulled out from streetside, with just a little bit of finagling around the main waste pipe grommets. Most difficult part is the plumbing that's in the way of pulling out the tanks and the wedges including the maniblock. When I finally figured out that those platforms were wedges though, it sure eased my mind because I did not want to cut those waste pipes or vent pipes!

Fortunately the tanks are amazingly light weight. In our coach the black tank was that of a struggle because of a slight angle in the toilet waste pipe. I found that removing the grey tank first, I was able to tilt the black tank to create enough clearance to ease it out. All in all, seems to me a very elegant design
