That Eco Pure thing looks quite good. I am constantly amazed at just how crappy boat plumbing fittings are. Yes there are some very good but hellishly expensive European fittings but the average chandlers product is appalling.
I can't quite see but I'm presuming cold water only ? Not that this is an issue as I have long since given up trying to find an exceptable hot water solution for a small boat other than solar bag or kettle.
