Last night I added bleach and let the pump run. This morning I find a pinhole leak in the flex hose between the pump and the filter. I am considering adding a SWG in the future, could it be placed between the pump and the filter? If so I could go ahead and put the unions in there now instead of redoing it when I end up getting a SWG. The space between the pump and filter is about 1.5 to 2 feet at most.
