In a previous life long long ago i had a Abbey caravan & if we had a water supply just for us i could plug it directly into the caravan with a special block/plug. My question is can i do the same on the 2015 eriba 320 or am i going to risk blowing something up/off

If you have the Whale Watermaster or Truma Ultraflow inlet housing you can connect mains pressure water via the Whale Watermaster Mains plug and hose adaptors.

This plugs directly into the Watermaster housing but will need an adaptor if you have the Truma Ultraflow housing.

The Watermaster Mains reduces mains pressure to 1.5 bar which is a similar pressure to the Watermaster High Flow pump.

Other systems are available which fill the Aquaroll from the mains. The level is controlled by a float valve in the barrel.

Will this work if you have an on-board tank?

Hi Magpie
I don’t have an onboard cold tank, I use just one of the Aqua roll things. When I bought the caravan off AVL I got them to add a electric hot water tank/barrel which they put under the very back seat, eg below the table mount. I might just ring them to check that it’s not going to bother anything, I can’t see it being a problem

I have an aqua roll which I’ve used for a couple of years & probably just being lazy. It’s just I still have the plug/ block thing that plugs into the water socket on the side of the caravan where I normally plug the aqua roll in & on to the site tap but I don’t want to blow anything

If you are parked on a serviced pitch then you would be able to fill the onboard tank from a hose pipe connected to the pitch's tap.

On my previous caravan long ago if there was a dedicated tap to just my caravan i would just leave it turned on. no more running out in the rain to make a early morning coffee etc, it was just fit/turn on & forget

But I have been told this is not possible if you have an inboard tank and I'm just trying to find out if it is.

Or, this setup works.

Mains-pressure water fills external tank (Fiamma/aquaroll etc) which is fitted with a float switch (to turn off the water from the mains supply when it is full).

Water pump also fitted to external tank which pumps water (at low pressure) into the onboard tank, obviously when the onboard tank isnt full.

This is controlled via a non-contact level sensor fitted to the outside of the internal tank that drives a relay which turns the pump in the external tank on and off so as to not overfill the onboard tank

This setup has two modes of operation.

One, when on a serviced pitch the onboard water tank is always kept full since its always topped up when water is used from it. The external tank is also always kept full by the mains water feed/float switch.

Two, when not on an serviced pitch, the external tank is filled at a water stand. When then connected to the onboard tank the latter is kept topped up as long as the external tank has pumpable water in it - useful particularly at night to ensure you have a full onboard tank before retiring (all controlled via an on/off switch for when the external tank is emptied)

The onboard tank is useful of course for wild camping or where water supplies arent available.
