Mains water through Truma ultraflow / on board pump

[MandM1]

I'm looking at getting hooked up to mains water this summer. My options appear to be the ballcock in aquaroll. Seem lots of cheap homemade kits on ebay - anyone got any experience of whether these are any good or should I just get the genuine aqua roll one. I've also looked at a truma one that goes directly into the ultraflow connection on the van. How do these work if you have an imboard pump? Can they be used with an inboard pump?
Any advice much appreciated

We had the same dilema a couple of years ago. i decided to purchase an aqua roll float value, which has worked perfectly for us. personally i would not want to use a mains kit. as i would not want mains pressure anywhere near the van. yes i know they have restictor valves on them, but i would not want to take the risk, just my opinion!!

another thing the aquaroll one can be used with any caravan , where as the caravan mains type will only fit what ever water system is on the van

I personally prefer the float valve type for some of the reasons already given, and for few others
The inline systems are fitted with pressure regulators, but whilst they do limit the maximum presure the caravan will see, they can also introduce some flow restiction. Consequently you can often bet a better flow rate from the normal pump.and can suffer from a significant flow restriction.
On some sites the water availabilty to pitches can vary considerably depending on how many peopole are drawing water , Having teh float valve system removes the pressure and flow fluctuations.
And I cant reiterate the possibility that the pressure reducer valve on the online systems could fail and the internal water sytsem coudl them flood the caravan.
