Image of the pipes into the Waste Tank, as seen lying on my back!
The new one is seen as black.

I have attached an extension pipe from the overflow to the edge of the chassis, so I can monitor any overflow easily.

In the narrow sections of the pipe you will find, as I did after 6 years, that they will crack at the slightest touch.

The Jubilee securing clips will have to be cut off. When replacing liberally cover with grease for future ease of maintenace.
