Ok, thanks for that. I think that the advice for a liveaboard being different to a leisure boat is the constant, regular usage. Every day as opposed to some weeks during the year = more wear and tear. The guy on the phone recommended a CW343A Flomax pressure pump, but he works for them and it comes in at £322 so I wanted to know what actual boaters have to say. It dors have an external pressure switch and an 8 Litre accumulator tank. Should probably mention that I have the galley, one bathroom, a domestic shower and a washing machine. 13l/m at 10 amps also works well for me but could be got cheaper. Quiet would also be nice!
