Hey I have a Hayward sand filter that let green by on vacuum so we ordered a new valve head from Amazon because I couldn’t get the old spider out. The new spring bonnet and handle assy came with a little baggy with two orings and a Teflon washer with a split in it, anyone know what these are for? Not letting dirt by through the jets but pool won’t clear up! Gonna change sand and order a TF test kit asap. Thanks
