Sorry hopefully not wasting everyone's time, but novice here. I have an overflow box that the plastic screw has sheared off tonight. I have managed to zip tie it for now, but the question is how long will it last. I am looking for what best action plan. Replace the plastic screw and bolt or replace the overflow bow. The overflow box to my sump was bought used and maybe its time to replace. I have for the last year read your advice on others but now I need an assist.
