Re: Drinking water tank water.
It might be a good idea to have the water from your tanks tested at a city water treatment facility. It cost us 20 bucks for the test when we bought a house with well water in the mountains of NC. Surprising that the water tested positive for e coli, since the previous owners drank that water and appeared healthy.
On the boat I've always used the water frequently so that the turn over between refills was less than 2 weeks. That seems to be key in keeping the water fresh assuming you have a good source for filling the tanks. Now that the boat is not being used as much my concern is water that remains in the tanks and lines turning bad with time. Even though as much water as possible has been removed the tanks, they are not completely dry. I put in non toxic antifreeze and pumped it through the lines with the thought that maybe that stuff will keep the system contaminant free until the tanks are returned to service. Hopefully that will be sooner rather than later.
