Hi
just bought my first caravan but being a bit naive bought an ill equipped one. it has a carver cascade housing for the external water pump
but I cant seem to find the right connection for sale all the the filter is a blue oblong shape and the 12volt connector is between the two water inlets.
does anyone know what pump I should buy for this set up.

Hello Paul,

Welcome to the forum. Please ask any questions you like.

Your description is a little confusing, so let's try to clarify what you actually have. The Carver Cascade is a water heater and does not have any pump connections. Carver's pump system was called the Crystal, but it was moulded in white plastic. Carver stopped making these in 2000, when they sold their caravan leisure revision to Truma. Truma continued to supply Carver designs products for a while but soon brought out their own versions.

I have seen a number of aftermarket counterfeit copies on the internet in different colours, so it's possible a previous owner may have replaced the original Carver unit for some reason.

The crystal system was originally both a plug in pump and and activated carbon filter system. The filter was a screw in cartridge with a clear plastic cap and the later MK2 had a twin port plug in filter which was moulded in blue, but the housing in the caravan wall was still white. Your reference to the two water inlets suggest you may have a Crystal MK2.

Other manufacturer's such as Whale, also produced plug in pump systems, so it's possible your pump inlet is not a Carver after all.

It may help to Google "Carver Crystal" or Truma Ultraflow" or "Whale water systems" and view the images to see if you're inlet matches any of them.

........is it possible to ask the person who sold you the caravan if they forgot to give you the water pump as you can't locate one in the caravan.
Worth a try :huh:

Your description sounds like it could be a Carver Crystal set up .........
If you have a Carver Crystal Mk2 housing (now discontinued) then Whale sell a replacement pump.
