Water mains connectors

JOKERNELLY

Hi

I have recently started caravanning and have booked a fully serviced pitch and therefore need to invest in a water mains adaptor. I have a Sprite van with an onboard Ultra Flow pump (Truma). I think my choice is an Truma Ultra flow Waterline (direct to van) or
an Aquaroll mains adaptor (still using an Aquaroll). If anyone has some advice/experience on either of these that would be great. Can they be used with an onboard pump?

Any help would be appreciated.
