Anyone had any luck working with the white sanitary waste system reinforced hoses? The white stuff seems to be the only hose stock that marine stores carry these days other than reinforced bilge pump hoses?

The current challenge is trying to replace my clear plastic cockpit and sink lines with reinforced tubing.

I guess that the white stuff is very reliable, but how on earth do you get it to slide onto a pipe or through hull fitting? Soaking in hot water doesn't get enough hose on the pipe for a second hose clamp. The vertical distance between the valve and the downspout is short and the "T" to the sink must fit into that space also.

The white stuff says "1 1/2" but it sure doesn't slide very far onto a one and a half inch cockpit drain fiberglass down spout.
