Hi, I was curious to see if this has happened to any other pool owners that own a Hayward cartridge filter. The filter is approximately 3 and a half years old. Over the past year, the tie rod has become very rusty. Any explanation as to how this could have happened?
Here is a link to the manual - http://www.haywardnet.com/products/Manu ... ual135.pdf
All thoughts would be appreciated. Thanks.
