Hi Chris,

Well, that's a shame...It's all cast iron pipe here in Toronto...

I put in seven ground rods around my house, each 10 feet long and 3/4 inch =
diameter...Standard copper clad steel electrical ground rods from the DIY s=
tore...

They are bonded together with two 6 AWG wires, one at ground level and the =
other at about 6 inches above ground. Hose clamps and Penetrol for bonding.

I tied the system into the city water mains with 1/2 inch copper tubing...

Seems to work quite well so far...
