Hi Andy,
Do you have pictures? Sounds interesting. 🙂

Did you pre order your van? We ordered our new 530 nearly a year ago and still haven't got it

Inspecta_Gadget - yes I have pictures, I will try to post them
Old Rocker - NO we didn't pre order, managed to find one that meet our requirements (or so we thought!) in stock

Binky Webster on FB has just fitted this no return valve on her Comet pump and asked me to post this on her behalf.

She hasn't tried it yet !

Update I have located a truma 10mm NRV which I will put in the line (behind the external fitting, inside the van) .
I am sure this will sort my backfilling. Hope to do it over the weekend.
Will report back

Hi Andrew

I have the same additional pump fitted to my 2018 Triton and don't get the siphoning effect you describe, so I've been lucky in that regard. I can't see a non-return valve (see attached pic) but maybe its fitted elsewhere in the system.

For sealing the aquaroll, I bought something called a W4 aqua cap (can't post a link yet, as a newish member)

Its kind of ok, but I now need to buy a large hoseclip to ensure its attached to the aquaroll securely

TBH, its a minor faff to set it up and although its nice to know we have the option of larger reserves of water on a longer stay, I'm wondering if its easier just refilling the onboard tank more frequently. I guess I'll find out what works best as I go along (we're only out on our first week, so still on a voyage of discovery!)

Hi JohnE

That's really useful! I've been looking on the comet site for information on how to use the additional pump and couldn't find it.
