The PB installed a Skimsaver Lid'L'Seal (Link here) on my skimmer. Due to the fit of it, they didn't put the wier in the skimmer. After looking at it tonight, I think I could get the wier to fit in the holes as the holes are partially covered by the Lid'L'Seal.
Is it really worth the effort to mount the wier if I run the pump 24x7? Any advantages to the wier?
