Rather than use the normal caravan type convoluted pipe I use rigid poly pipe as used in domestic installations. by carrying 2 x 2m lengths and 2 x 1m lengths plus a few assorted connectors I can get a good run for the waste water without the pipe sagging and trapping the water. The solid pipe also keeps the pipe close to the caravan and is less likely to get trod on. For the fresh water I have 15m and 7m hoses which can be used on there own or joined with a simple connector. As to connection to the caravan for fresh water I use the Truma system most of the time but thre are a couple of sites I go to where the water flow rate is a bit unreliable (especially when the 'little darlings' turn my supply tap off when I am in the middle of a shower...) and on those sites I simply unclip the Truma adaptor and pressure regulator and use a float valve on the Aquaroll. w
