Hey guys so I noticed yesterday my pressure gauge on my filter was reading zero as to when I first got it replaced it was reading at 15-20. Then I checked the returns (jets) and noticed the one on the shallow end isnt working at all but the deep end is. I have no idea where to start to fix the problem. Not sure if the gauge not working and return are associated. Need some guidance before having to ask a professional for help who will overcharge and be busy for weeks.
