This is my second season with this pool, and this year I opened it myself. However, I’ve noticed that my Hayward sand filter is making a strange noise, and I'm not sure if it did that last year as well. Can someone analyze this sound and let me know if it’s normal? The water level is up to halfway on the skimmer, and I don’t see any bubbles in the pump window. The gasket appears to be flush, and the returns are working as expected.

There is a slow drip coming from the return line. When I tightened it, the drip shifted to the valve port side, as shown in the second picture. I believe it’s the same drip and that water is traveling over there. I will fix the leak in the return line, but that shouldn't cause any issues since it's just the return.
