I would agree 100%.seabee570 said:i think the main concern with not filling fuel tanks is water would condense on the top of the tank and contaminate the fuel
Clarkbug said:deionized water would not be a good idea to fill your system with. Having worked on several lab buildings in the commercial plumbing field, metal piping is not used for any of the connections. While a good portion of this is to eliminate the seams that would be created at fittings etc. that create sites for bacteria growth, the other is what Fred61 mentioned. When you remove the ions from the water, it will readily try to take back whatever is available from the system is in. Plus I can imagine it would be incredibly expensive to fill a residential size with DI water. And by the time you get it to your house, unless the truck that brings it has been cleaned/sterilized, it probably wont be DI by the time it gets there.

DI water is indeed an effective solvent and will leach material from pretty much whatever it comes in contact with. This leaching increases with temperature and contact time. There is a case for using it for at least part of a system fill-up, however. If you have hard water, you can blend DI or RO water with it in order to bring the total hardness down into the optimal (50 ppm?) range before you start adding chemicals. This will not add Cl- the way a softener will, and can also reduce your initial chemical cost because you are no longer fighting the excess Ca+ and Mg+ in the base water. If you need a quantity of DI water, you can buy or rent a DI resin bed and fill through it for part of the system fill. If you use a lot of make-up water and want to blend that, a small DI vessel can be paired with a mixing valve to produce an ongoing supply at the desired hardness.
