I have 3 return line jets to our pool (and 2 skimmers and no main drain as it is failed). The return line closest to the pump has the fastest flow, the 2nd closest has the 2nd most flow, and then the third is the furthest and has pretty much no flow to it. If I was to rank them on 1 - 10 scale (1 low, 10 high in flow rate) this is how it would go:
1 (closest) - 10
2 (2nd closest) - 6
3 (furthest) - 0 - 0.5
This 3rd return line used to have a higher flow out of it last year and the year before. Any idea why this is not generating water flow from it? The pump PSI stays at 20 normally and has been running at that so far this year consistently. It does creep up as normal and then I backwash but probably only every couple of days (or after heavy usage). I'm hoping someone can help identify some ways to narrow this down to what the issue may be. Any help would be great.
