I am attempting to acid wash the flex-tubes from my Hayward EC75, and I'm hoping to get some clarification on how to do this.
I took the "top" off of the filter (the flex-tube assembly and the 'lid' with the bump handle) and put it in a TSP soak on Sunday. I was getting ready to do the acid soak in the same manner and I'm concerned about the rubber gasket where the flex-tube assembly bolts to the lid. I can't imagine it would be good for a rubber gasket to get acid washed...
Should I unbolt the flex-tube assembly from the lid and acid wash just the flex-tubes, or it is ok to soak the whole top of the filter?
I'm in an industry where some things get ruined if you take certain parts apart, hence my caution.
The flex-tubes have been sitting in the empty container I TSP soaked them in since Sunday. Since I didn't immediately acid wash them, does the TSP soak need to be redone?
