Draining for freezing temps.

[CrewOVtwo]

Can anyway recommend a good, easy/ not too technical way to remove water from the system, should a sudden freeze happen?
Not only for at home when the van is on the driveway, but also for if I was on a 2 day ferry to Spain in subzero temperatures out at sea?

I doubt that a ferry going to Spain would see sub zero temperatures especially if the outfit is inside the ship. But even outside temperatures are influenced by the temperature of the ocean. It’s not a PQ17 journey to Murmansk.

All I ever did was drain the system down prior to leaving a site by opening the drain valve on the hot water tank and all of the taps including the shower. A lot drains out on the journey. When not being used in winter if it was on the drive or in store I would uncouple the shower head and blow down the hot and cold lines.

I always blow out via the shower , the highest point of the system,removing the head and then pump water out connecting to the hose. Never seen the point of the Blowndown kits for the water inlet, blowing water uphill.

I have always done as OC and Birdman, BUT when one of my water pumps for the aqua roll decided to go unserviceable, I converted the connection head to the caravan, into be able to blow water out of the system, I was amazed as to how much more water came out from the system.
For myself it's a case of open taps all round connect the fitting to the caravan, run the low pressure air pump 12psi, close taps except one, at a time.
Works for me.

i use my tyre inflator to pump 15 p.s.i. into system, plenty of vids on you tube.

i use my tyre inflator to pump 15 bar into system, plenty of vids on you tube.

Most caravan systems would blow apart at 15 bar!

At first I used the hand pump for our air awning, but found the running around a PIA. So used the air pump instead. Whatever you find best. Hopefully getting away in the next two weeks, don't mind the cold, but not the rain.

For those with an air awning, the foot pump works well to blow through. At least I hope so. Will know better after the winter.

Did exactly the same way as OC open the drain valve,taps and shower but with our caravan on a seasonal pitch it seem to take a long time to empty .

You should take it a run around the site that will help drainage. Get the mover boosted 🙈
