I have an 11 month old Hayward EC75A D.E. Filter. It is rusting inside (tube sheet screws & nuts). I have a chlorine pool with vinyl liner. Is this common?
Yes. Except there have been people who like to dump various powders in the skimmer to let them dissolve in the filter. Just checking you weren't one of them.jimdee1 said:Thank you for the reply. No, I have a Pentair Model 320 in-line feeder that I have always used only trichlor 3" tabs in. The rate of chlorine usage has always been very moderate. I am the only one that services my pool. Wouldn't it take high levels of chlorine to cause rust like this on marine grade stainless steel, over a longer period than 6 months?

Dear Mr J. A.,
The problem you have is not common and it could relate to water chemistry. The screws and nuts are manufactured of marine grade stainless steel but highly acidic water could still cause them to rust. Please contact the dealer that you purchased the filter from.
Regards.

Then, the response from the dealer:
Dear Customer,
Thank you for your recent Amazon/In The Swim inquiry. I apologize for the inconvenience, I spoke to our tech specialist and they said the same thing, this is not a common problem on these products. It is likely caused to high acidity in the water chemistry. Unfortunately, this is not covered under the warranty, and the product actually only had a 1 year manufacturer's warranty.
I apologize for the convenience.

After checking my paperwork, I notified the dealer 1 yr. & 2 days after I ordered the filter. It was actually only in use for 6 months. I am an experienced and knowledgable pool owner and my water chemistry is always well within the recommended guidelines. I am shocked at the responses from the manufacturer and dealer. I am going to post pics and results as I investigate the cause of this rusting.
