POOL WEIR REPLACEMENT WEIR CUFF The weir cuff that fits into the vac lid in the weir helps the regulator valve of the pool cleaner to sit tight and not to wear out the swimming pool weir vacuum lid.Upgrade your swimming pool’s skimming system with our high-quality weir cuff. Our weir cuff is designed to improve the efficiency of your pool’s skimming system while protecting the skimmer vacuum lid from wear and tear. TIP: If the weir vacuum lid is cracked, the swimming pool pump may get air into the suction line that will cause air-bubbles at the water outlet into the pool. This is one cause of the so-called “suction leaks”.
