In laws have just bought a brand new Swift Challenger and the first time 
they took it away the pump was making quite a noise. This is an internal 
pump, not one that fits into the water container. They spoke to the 
dealer they bought the van from (one of the largest in Scotland) and 
were told that others had mentioned this but that there was nothing that 
could be done.

Has anyone else experienced or heard of this kind of problem and if so 
is there some sort of fix? They will be contacting Swift as well but any 
light that can be shed from the illustrious contributors here would be 
most welcome.

Regards,
Ian

I have read of other caravans suffering similarly noisy internal pumps. 
I think it helped to check that the fixing screws /bolts had not been 
over-tightened - compressing the sound insulation mountings down too 
much and thus passing the vibrations into the floor.

I think Harry is right.

Most caravans are assembled using power drivers and the torque settings
need checking regularly (I used to work for Desoutter supplying them)
and tightening screws into wood or plastic further than they should be
is probably worse than not tightening enough.

If it were me, despite what I said in an answer to a very similar
question last year, I'd probably remove the pump and re-locate it
somehow with a thicker gasket of closed cell foam/rubber mountings, as
used on our fish tank airpump (very similar device) to insulate it
better than standard.

Bailey's were the first to fit this pump and there have been numerous 
complaints since. Whale, who manufacture them, insist that people are not 
priming them properly and leaving air in the system. They also say that 
motorhome owners have had this system for a long time and you get used to 
the noise once the airlock problems are sorted. When it happened to me I 
attended one of the national club rally's where Whale had a stand and two of 
their engineers spent over two hours sorting the problem out. There is still 
some noise from my system but, to be honest, it is acceptable. The real 
nuisance is that when on electric and the hot water is left on 24/7 the pump 
suddenly runs unannounced as evaporation causes the system to equalise. This 
can happen in the night and comes as quite a shock! Good luck, Harry P.
