Sorry for my poor English ;-)

I meant I think that I just overpaid by buying the Jobo version, as it really has the same label as here:

I actually bought it for the mobile water supply (version with the jack plug).
Now I have an overengineered water supply on steroids ;-)
using the Jobo Heater (from the mobile water supply kit) in a canister,
in combination with a Shurflo caravan pump which gives me up to 3 bar pressure.

As I extracted the old pump, I saw that it really looks the same, just red.

What I meant in regard to Mr. Seynsche:
As I approached Mr. Seynche I did only mention that I have a Comet Elegant 12V pump,
and did not say anything about that I bought it from Jobo.
That demonstrates that the Jobo Pump version is no different from the comet Elegant version.

And I mean, what could go wrong anyway? It's just a circulation pump ...
My setup runs stable now for many hours, so that's proof enough for me anyways ;-)

Best,
