“I opted for 40 mm hose and matching cam lock fittings, having previously used 25 mm sullage hose. The quality and price of these items was very good. I probably under estimated the size of 10m of hose in terms of packing and storing in the van. So I made a 4m and a 6m hose in 2 hose bags. This gives flexibility to join together if needed wih the cam lock fitting. So far I have not had issues with water drainage in the van shower, as sometimes happened with the 25mm hose. V Happy.”
