Caravan water supply - serviced pitches
We have just replaced our motorhome with a Bailey Unicorn Córdoba twin axle caravan. We would like to use serviced pitches as most of our bookings are for two weeks on average and lugging waste and water hogs around for two weeks is not appealing. My question is how do you arrange the fresh water supply on a serviced pitch? The van has two pumps, an internal one to feed from the on board tank and an external pump feeding from a water hog. Can I just buy a long hose with a Whale adaptor and feed mains pressure into the van through the outside connector? I'm worried that this will override the onboard pump and possibly flood the van. Any help would be much appreciated as the Bailey owners manual makes no reference to a mains water supply.

I don't know about a Water Hog but with an Aquaroll you can buy a mains conversion kit which turns the Aquaroll into a sort of cistern which automatically replenishes the water to a certain level thus allowing the usual pumps to work in the same way as not being connected to the mains. You would need to check with Bailey whether the caravan system could cope with direct mains pressure.

Not sure about the Whale system, but the Truma system fitted to our 2017 Lunar Delta can feed directly into the van, replacing the normal submersible pump feed from the Aquaroll. Our van also has a similar onboard tank/ pump setup. The standard Truma mains hose incorporates a pressure reducing valve, though this hose is quite an expensive extra (about £70?). The control panel takes care of the pump switching when using the onboard tank system. An alternative is to use a ball valve arrangement in the Aquaroll/Waterhog as previous comment, keeping the submersible pump in the external tank.

The whale and truma systems as i understand them are both available via a flexible hose and pressure reducers in the van end fitments ,but i am not sure i would want to rely on either being "reliable" enough to not fail, and the van being flooded when the internal pipework is subject to mains pressure,
Imho i would go for the aqua roll adaptor as described in DKs post

I use and prefer the Aquaroll fitting which keeps the Aquaroll half full and I do not have any worries about the system failing and flooding the van. Should my aquaroll system fail, then any flood should be outside, unless the actual caravan fitting fail. Since the Aquroll system screws into the side aperture, and I think that the Water Hog aperture is a similar size then it should work.

We also have a Bailey Unicorn, and always use serviced pitches. I initially used the Bailey hose with the pressure reducing valve fitted, as a direct input to the van. We found that it reduced the pressure too much, resulting in really poor pressure in the shower. We now use the "through aqua roll" system as described above and find it much better. The Bailey "external" pump produces better pressure than the reduction valve.
There is no need to use the internal tank on a serviced pitch, as there is no means of automatic refill. You have to lift the bunk seat and turn on the internal tank filler valve every time.
