Today I found a leakage on the return fitting. A drop can be seen coming from the fitting outside thread. Attached a picture showing where the drop is forming. This is a 3 months old pool, so I think it might be too early for a bad inner gasket. The nut also seems to be properly tightened, although I have no proper tool to tighten it more. Any suggestions on what else to check?
