Hi all. The old Crystal 2 water inlet on my Adria leaks like hell - I suspect the housing is cracked somewhere. I want to replace it with a new Truma Ultraflow inlet but use a Whale Watermaster submersible pump and hose with the Ultraflow compatible connector. The existing Crystal 2 inlet is the compact style, i.e. without a filter Is the Truma Ultraflow compact inlet a straight swap, i.e. it fits in the same cutout in the van wall? And will the Whale pump fit OK in the compact Truma Ultraflow inlet? Thanks in anticipation.
