The steel spirals in the water – are they easily purchased locally?
The “Cathode” (the wire connected to minus 12 Volt) is made of stainless steel grade 302/304 that can be locally obtained from marine stores and hardware stores. The “Anode” (wire connected to PLUS 12 Volt) is made of stainless steel grade 316L that can be obtained from several sources that specialize in metals (given in the book). It is easy to obtain once you know who to ask, and we will tell you our sources. They are in the USA, and if you are elsewhere in the world you can find 316L on the internet or at your local metal supply, they will know what you’re talking about when you say this “code”.
