Air in water system/Pump?

[mapa]

Are you absolutely sure that the dump valve on your water heater is closed? It sounds like its been left open and the water is flowing out as it pumps. I've done this before. Look underneath the van while the pump is running. You will see water coming out if its been left open.

Phew

Yes some of these problems can be hard work even at a distance

I'm knackered now with all this brain work.

Not that I wish Normandsue problems, but I LOVE these posts. I've just started wintering my 'van (plan to use water flagons if I go on a trip) and all of these tips will allow me a bit of a heads-up if it goes belly-up! I knew the previous van's foibles, but I'm about to attack this one with a Floe system to purge the latent water. What's the betting that there will be no water flow when I re-fill it

Yep Quite sure, I closed it myslef and checked beneath the mh for any water leakage. Just watching weather forecast before draining down again

You could try priming the system by removing the shower head, holding the hose high and pouring water down it until the whole line is full, then while still holding the hose up, run the pump and see if that primes it and bleeds the air out. I am given to understand that most pumps are self priming nowadays, but a bleed point in the line would be useful!! Good luck and please let us know for my own future reference how you get on.

I had the same problem and googling I found this solution and it worked, thanks!

On my old Burstener i had to rock the trauma boiler back and two to clear the air everytime we filled up. On new Bavaria had same problem close all taps and only open one tap very slightly the furthest tap from the boiler and you should hear the air being forced out.
