Replacing Whale outside inlet cover

[kay4]

The flap on the outside of our caravan where water pump connection fits has snapped off. We have a Whale type system, however when I have looked to buy a replacement it gives two options Microswitch or pressurised. How do I know which one to use? I own a 2008 Ace Firestar if that helps?
Thanks in advance

I had trouble with my water inlet connection, so I phoned whale and asked if they had a customer services help desk. They put me through to a very nice man named Mark who sorted the problem out for me over the phone in minutes. Look in any caravan magazine for the whale advert and ring them up. They were very helpful.

Whale are one of the most helpful companies in the industry and in my experience will always give you a helpful and truthful answer to any question about their products.
