I am not very experienced in plumbing so I am asking for advice. I have acquired a new pump through a little trading. There will be a sink in the galley, and will have a water storage container under the counter along with a seperate container to catch the waste water.
As well as having this water supply I want to be able connect to a pressurized water source if there is one available. This will give me an alternate choice of supplied water.
My question is how do I plumb it all together? Do I need back flow preventer valves, and where do I need them? Do I need valves in place to close off the system i'm not using at the time? Any tips would be greatly appreciated.
