I`m thinking of buying a Whale aquasource mains water connection kit. Has anyone had any problems with it? The reason i`m asking is that my piping in the caravan will be under constant water pressure with this piece of kit. Price from Towsure is only £46.95. If I go with the other system of an Ultra flow Waterline @ £89.95 then a new Aquaroll (with the side cap) @ £49.50, Total £139.45. A saving of £92.50 will be made with the Whale but will it be worth it? Regards, Peter
