Sloshing noise!!

[The Trucker]

I've had my chim for a week now and just completed a 450 mile round trip to Devon with no trouble at all (apart from my face aching from grinning for hours!!).The only thing that gave me cause for concern is a loud sloshing noise coming from the passenger footwell.I've had a quick look and I assume that it is something to do with the heater,it is working fine but I don't think it should be making this noise.There is no pattern to it and I can't replicate it,it just seems to do it as and when it pleases and sounds like water under pressure being forced down a pipe.

Do any of you knowledgable blokes have any ideas or do I just turn the music up?

Cheers,
Paul.

Thanks for all the advice,it is definitely not water in the doors or sills and is most likely to be air in the system so I'll try the priming route first rather than replacing heater valves.

I'm glad to know it is'nt just me who has the problem!!

Thanks again,
Paul.
