Draining down!

This maybe a daft question but we are new to caravanning and have set up the van on the drive to test everything. We go on our first trip locally soon. Do we need to drain all the water and empty the toilet cassette that we just filled to test the flush before we tow? Thanks 😊

Providing the cassette isn’t near full, it won’t hurt to tow with water in it but why not set off with it empty to give you greater capacity for use when you need it?

I’d not empty the flush or any other tanks you may have unless you're weight critical.

If you have a newish van then it is likely that any additional fluids will be eating into your paltry load allowance of around 150kg by as much as 37kg if full.

For this reason I always drain down the water heater 10l, the flush 7l and empty the cassette approx 20l the charge it with a dose of toilet fluid.

We always drain down not only for the weight but because it can be become a "live load" ie sloshing around

I am a little confused. Sorry its all new to us!! We have a 2013 bailey unicorn madrid  with alde wet central heating. I don't think we have a tank, doesn't the water just come straight from the aquaroll? 🤷‍♀️

First of all, does your van have what’s called an on board water tank? If it does, then travel with it empty to avoid the large quantity of water moving around, it can make a difference to how the van tows, if it doesn’t have baffles. You can simply travel with a small water container inside the van for any cups of tea or hand washes while enroute. If you have a system where you use a water barrel, then don’t fill this, but fill up and connect when you get to Site. Again, a small amount of water for travelling. We used to travel with a loo ready to use, for any breaks, if it flushes from an on board system, simply flush with a container until you get to site, then set up as normal.

The three main things are, don’t have a large amount of water onboard when travelling, keep an eye on your weight, and don’t have water standing for weeks in your system. Some outfits are only used a few times a year, so best to freshen things up.😁 Enjoy yourselves, it will soon all be second nature.

The fluid in your Alde central heating system is a sealed circuit, much like your home central heating, it usually has something added, (anti freeze) but only needs draining down periodically, so leave this alone. The water for showers, taps etc, is what is drawn in from your Aquaroll, completely separate system. Your need to empty the water boiler before travelling, carefully, as it might be hot once you have been on site. More important in Winter this last bit, to stop any residual water left in boiler from freezing.

If you haven’t done so, have a good read of the Club’s handbook for some good tips around towing safely, laying up a van for Winter etc....  It’s probably on website somewhere as well, but things can be buried rather deep on here👍😁

Thanks for that! There is so much to get your head around! I'm sure it will all become clear.....eventually🤣🤣 We don't have an onboard tank we just use an aquaroll so do we still open the yellow drain valve before travelling?

So is this the yellow drain switch?
