I am interested in using Super Sites with direct water connection. The system in my Swift Challenger is Truma, and looking at their own brand direct to mains connection, which they say includes a pressure reducer. I am also looking at the Care-Avan adapter
with ballcock to fit into my Waterhog container. My question is, does the adapter type need a seperate reducer, or will the ballcock type do the same job. There is considerable difference in the prices.
