I have an inground pool. About a week ago, a PVC pipe connected to my Hawyward Superpump became dislodged. We got the pipe repaired. Since then, we noticed that when the filter is on, lots of air bubbles come through the jets in the pool and the filter is noisier than we recall. The filter is a Hayward S200 Series High Rate Sand Filter. The pool guy came and recommended we let the filter run for 24 hours to get the air out. We kept the filter on as recommended but there are still more bubbles than in the past and the filter is still pretty noisy. Please let me know of any suggestions to fix these issues. Thanks.
