Can you buy a drain down kit for a 2023 Adria Twin Supreme?

[AliTwin]

Hi, I drained down the entire system according to the manual and by watching YouTube videos before the frosty weather came. However, I want to go one step further and use an air to pressurise the system to get every last drop out. Does anybody know what I need to buy in order to do this? Thank you

Floë drain down kit?

 

[Cush]

Have you got an external shower? Blow down that or take the shower head off and blow down that while the dump valve is open and mixer taps are on central position ? Don’t think you’ll ever get every last drop out.

I purchased the 'tyre valve' part of the Floe kit on Ebay and, with a couple of isolating valves, set it up successfully. Works very well and drives out a surprising amount of water. Just leave the air pump running and walk around opening taps.
The purchase was after I forgot about the external shower in the garage first winter.

No outdoor shower. I blew down the internal shower pipe.

Where do I attach the floe kit to though? Where I put the water in? Do they have a specific attachment?

Just broke into the outlet from the pump - hence the need for isolating valves. One valve to stop the air being pushed into the tank and the other to stop water being pushed into the Floe adaptor. It's on the van permanently.

DIY water system forced drain down

After investigating a branded drain down system I discovered it would cost me £54 for the kit to do European motorhomes with flexible pipework :Eeek: So I made my own for about £16 :Cool:

I knocked up a tyre valve in a compression fitting it screws into the shower pipe and I use a cycle pump

Hi Phill , how did you fix the valve into the compression fitting. thanks

That's exactly what I do. Like others have said, I don't think you'll ever get every last drop of water out the system.

I’ll do a photo tomorrow for you

I use a variation on Technos theam using JG fittings. i soon forgot bike pumps or HP pumps and use an air bed pump rammed down the 12mm pipe.

Ok another photo for you,
It’s a simple plumbing compression fitting, and a tyre valve I had spare. Trimmed base of the valve rubber so it is a tight squeeze into the main body of the fitting and simply screwed the nut part down on it.

Very basic and very effective.

A good idea but you would need to be very careful not to over pressurise the system and blow a joint apart.

Thanks Phil, do you screw that into the exterior water filling point then? Sorry about all the questions but I’m new to all of this. Ive had VWs before but didn’t ever bother with water.

I Just use a cycle pump. You don’t pressure the system you open a tap at a time and blow the excess water through.
Then with the dump valve open pump through it through. really not much more pressure than putting your mouth over the shower hose and blowing through the pipe.

I c screw to into the shower hose same thread on fitting and hose hand tight!

I am not sure that I understand the necessity to get out 'every last drop'. If there is no substantial water in fittings like taps, showerhead and pump then any drops freezing have room to expand, so no damage is done.

I do the standard process of opening all taps in the mid hot/cold position, drop the showerhead down to floor, remove and empty the submersible pump, dump boiler contents. Then all water drains back to fresh water tank and to ground when drain plug is out.

I have been doing this for 14 winters, including 12 in Poland, with no problems.

Maybe somebody will explain how that is insufficient.

I would not say it’s insufficient however , I have had the ceramic internals of 2 taps crack as a result of water droplets sitting in the mechanism and freezing.
That was after doing exactly what you do.
So now I ensue as far as possible any component is free of water by a simple blow through.

I made up a similar home made blowdown kit from a 15mm copper pipe compression fitting and tyre valves. Detatch the shower pipe from mixer pipe the connect the tyre valve. With all taps and boiler drain closed l used a tyre inflator to pressurise to 1.5 bar. NB Do not go above the boiler max pressure. Then open the tap nearest the shower and work to the one further away. Repeat until all water expelled. Don't forget the cassette toilet water flush press the button a few times.

you like a blow job then Phil

I think the problem is in the individual layouts and posibly the susceptability of particular components,
Like Phill D ive had at least 2 problems (memory) one in a dismantled mixer tap just lying there totaly disconnected. Obviously your method works for you, for others with new (to them) vans do to you take the risk new tap £70 3 month wait or adopt a different technique. Just dont use too high pressure thatl blow apart connectors or make them leak. I use a simple low pressure high volume airbed pump.

But have you experienced a Devon Winter?

Is that an invitation?
