Au contraire... deionized pure water is a fine insulator, particularly for
pulsed applications.  Typical minimum resistivity in this sort of
application is  2 Megohm cm.  The disposable DI cartridges do a nice job. 

Getting the pure water for home use isn't all that hard (you can buy it at
the supermarket).. keeping it clean is the challenge. The system will tend
to contaminate it, which is why the systems that use this approach almost
always use cartridge deionizers (or a big version of the same...)
