Flex Tube replacements?

[Craig]

Good evening all!

I keep getting diatamaceous earth in the pool. The grids look fine but the flex tubes are questionable. I am attaching some photos of the tubes and have no idea why they look this bad. Once a season I hose them down (perhaps too much pressure), soak them in TFP and then muriatic acid. I never had this issue before. My question is, do these flex tubes look like the culprit?

I understand how to replace them but was hoping to troubleshoot prior to starting. Thanks for any help anyone can give!

Let's see if @1poolman1 is familiar with the Hayward Perflex DE Filter.

Grids? TSP? No reason to use acid if there is no calcium on the tubes.
Take a bit of PVC glue and daub it over those worn spots. It should seal any leaks.
Haven't seen a PerFlex filter in this area for over 30 years. They re usually use on ABG pools here if at all.
That's a 32.5 sq. ft. filter, very small.
