    Where should I connect a zinc anode.

    I have a SWG pool and thought it might be a good idea to help protect the equipment from corrosion with a sacrificial zinc anode. My thought was to connect to the bonding wires near my heater and bury a zinc bar as a sacrificial anode there. Any thoughts or suggestions?

    Re: Where should I connect a zinc anode.

    Sac anodes work best when connected as closely as possible to the thing you want to protect. The funny thing though is that copper (i.e., heat exchanger) is fairly stable and unlikely to suffer galvanic corrosion. You can certainly hook it up to the bonding wire but the things that need the most protection are iron based materials like stainless steel hand rails or wrought iron fences.

    You need to bury it in moist soil. Being a fellow Tucsonan, you'll have to tell me where you find such a rare and mythical spot

    Maybe if there is a leak somewhere in my equipment area and I bury the anode there, but otherwise you are correct, moist soil is a very rare commodity around here.

    I was thinking of you had a nearby irrigation drip line that would be perfect.

    Tell them not to, those put zinc (metals) in your pool water and that is not something you want to deal with....

    this is what I used and bonded everything together... This zink anode is 30 times bigger than the one you listed and for my pool should not ever need replacing in my lifetime and its about 70 dollars cheaper.. I also buried mine within a foot of my equipment pad where it will get watered by emptying the pump filter, cart filter and purging air from my filter.

    I know this "may or may not" if it does not work I am out 17 dollars but if it does work YAY
