Draining down!

The yellow drain valve next to your water heater,can be open when travelling, as it is just the water from your hot tank,if.you also open your taps  it will also emptymost of ,the water from your pipes,if you really need to

When you refill the system from your aquaroll,,always put the pump into water before pluging it. Into the inlet on the C/van as this will very much the chance of an air lock In system

Yes it is. We have a similar model of caravan to you, and I drain down the hot water boiler into my waste water carrier before leaving each site, which then gets emptied as normal. I know that others don't always bother but I don't like travelling with the thought of water sloshing around in the main body of the van. As JK says the hot water damages grass pitches hence using the waste water carrier. I don't drain down the flush tank but make sure that it's not full before setting off but has sufficient water in it should we stop an route and use our toilet.

Just one more thing, I know it is obvious, but don't forget to shut the yellow valve before you refill from your aquaroll. Or you will just empty it straight into the ground underneath the van.

Been there, done that. (Only once)!!!!!!

I've also been there, done that (Only three times )

Travel with any tank filled to the brim then there's no room for slopping about.  It's probably one of those "all or nothing" situations.

I keep it as simple as I can during touring season and for many years have had no problem. The yellow drain valve is closed after a winter in storage, stays that way until the end of my touring season then opened again for the next winter in storage. If draining a few kilos from a Truma heater and associated pipework is necessary then you are flying very close to the wind regarding payload, then there's the getting rid of the air in the system after arriving at the next site. OK I may be lucky in having a close to 300kg payload and heavy capable towcar, maybe that's the reason I empty nothing when travelling

Whatever is in the toilet flush tank stays from site to site and only drained for winter storage, and whatever is in the Truma boiler also stays throughout the season. Aquaroll, toilet cassette and grey waste water emptied at the end of each site stay.

Each year all water pipes, hot and cold flushed with bug killing fluid along with waste drain pipes. Also fill and empty the flush tank annually a few times.

When we had a caravan with Alde heating we also used to drain down the boiler before travelling. We normally opted for hardstanding but rather than run hot water out onto the ground, we always emptied the hot water through the sink drains into the waste master, which gave them a good clean out. Then when we drained the boiler the water was cold.
Particularly before storing the van in winter it is worth leaving the yellow drain valve and taps open on the journey home. It shakes a few last drops from the system. Between sites it is better to close it after draining. I’m  another one who has emptied the first aquaroll onto the pitch on more than one occasion.

No, your hot water doesn’t come direct from the aqua roll, it’s heated in a small tank under a bunk. You might not recognise it as a tank because it’s encased in insulation, pipes and electronics. When you drain down, it’s capacity and presence becomes obvious through the volume of water released.

I start my drain-down as soon as I have finished with water in the caravan and before other jobs, mirrors on the car, electric cable etc etc. If I'm on a hardstanding I will let it drain out there but if we're on grass I switch off the heater and then run the hot water through the sink with cold water from the aquaroll replacing the hot in the boiler and then into the wastemaster to save ruining the grass. The cold water in the boiler can then be safely let go onto the grass. Opening at least one tap will speed this up. It is only fresh water so any that does run out onto the road is perfectly OK in my opinion. As others have said, remember to close the drain valve after the boiler is empty or before you try filling it again .

I have a small hot water heater just behind the axle and an onboard 35/40L tank at the front of the van. I pull the drain plug in the bottom of  the tank and empty it. I leave the water boiler and pipework full/primed. This water weight is contained and cannot move about in transit. Toilet holding tank is emptied, rinsed out and primed with 2 or 3L of water and chemical for next stop. Flush tank is ran low and if anything over a couple of litres in it is drained down into a 2L water bottle.

This set-up allows me to travel with minimal liquid onboard and yet be able to set up quickly.
