I cleaned my grid (filter nest) with a power washer and damaged the fabric on some of the flex tubes. I taped the damage with electrical tape, but I still get a green plume ejecting out the returns for a few seconds when I start the pump. A new nest is $500 and the filter is only 2 seasons old. How can I test each tube and only buy some tubes instead of a new nest? New tubes are $5 each.
