Good morning TFP’ers.
I clean my four filters twice a year (Spring and Fall). There is a negligible psi increase (or flow decrease as measured on my FlowVis flow meter) before I clean; maybe 1 psi if that.
I use a straight brass nozzle following what’s recommended per Chem Geek (Richard) Re: How to clean a cartridge filter.
I have four 25.5” x 7“ diameter cartridges. Installed 4/2015. I have never soaked them in TSP. There’s only some minor surface staining; what appears to be rust or the like. Bands are all still in good condition.
Sure, we perspire, use sunblock, but I can’t find any reason still to warrant using TSP. Am I missing something? What benefits would I see?
To disclose, I actually have never even done it for my spa filter.
