4 years ago, believed a sales pitch and my wife and I purchased an above-ground pool with a salt water system. Despite my questions to the contrary, the salesman assured me that the pool water would be "less salinic than a human tear" and that corrosion would not be a problem.
He has since "moved on" and the pool store acknowledges that the rep lied to many people. They also say he SHOULD have highlighted the fact that a salt system would void any warranties for the pool. Nice. I'll get to the question soon. On top of each post of the pool, there's a "joiner plate" which is made of steel. This plate rusts like crazy. Twice, I popped the caps and coated these things with an Eastwood product but I could only get to the faces...they are rusting everywhere. This year, they are crumbling into the pool. I've ordered 17 new plates and I'm planning to treat them with the best stuff I can find before installing them. Short of powder-coating, what might I try that will make the parts far more impervious to salt water? I *think* they are galvanized steel as the come from the manufacturer. |

I can think of only two solutions that might work with salt water pool. Galvanizing is a zinc coating that acts as a sacrificial anode so the steel won't rust. Once the zinc gets sacrificed off the surface, it starts to rust. One solution is to add more zinc to the galvanize, such as a zinc plate under or over the galvanized parts. Old car trick was to add zinc washers under bumper parts. You will need to add a bolt or screw to act as the electrical conductive path between the zinc plate and the steel.
The other one is to duplicate the parts out of fiberglass. Make them a quarter of an inch thick because glass isn't as strong as steel.. Ken |
