We did cut the plastic thin water pipes underneath the sinks, and just put the pipes into 1 gallon water bottles from store to let us use the sink manual water pumps. . .
Water tanks are OK if properly treated. Like most I do not devote much effort into treating the tank so I use bottled water for drinking and cooking, but to remove the water tank would be a mistake as water is needed for cleaning chores, as a cooling agent, showers and other uses. Last but not least it will diminish the sales value of the boat.In modern age do people use their big 40+ gallon water tank up front or do they go to bottled water, tank seems health risk AND BOTTLED WATER HAS GOTTEN CHEAP AND COMMON unlike the 1980s? Removing front h26 tank would free up room. - D
For at the dock usage, install a dock water inlet. Massively worthwhile projectJeesh.
Only in British Columbia's southern parts could one get bottled water. Our tap water is fine, and if you don't trust your tanks, empty them and clean them (see Peggy's post).
We use a "Rainfresh" (Canadian company) carbon and ceramic filter (under galley sink) when we are concerned. (FYI: Brita and PUR tap filters remove some chemicals and taste but NOT biological issues, such as giardia. Carbon/ceramic filters such as Rainfresh gets rid of taste, chemicals, protozoa such as giardia and some bacteria. But chemical such as chlorine - - or UV or boiling -- required to get rid of all bacteria and virusus. Chlorine not very effective for protozoa. Chlorine and good filter - - not Brita - - a good combination. )
But we NEVER use bottled water in BC, at home or on our boat. (We see a few buying it and wonder why.)
