Installation & Compatibility Notes
Before installing, ensure the skimmer is isolated and drained as required for winterizing procedures. Insert the IGWM-H plug fully into the skimmer throat opening so it fits flush and doesn’t obstruct the lip of the skimmer. Verify the fit is secure and that the skimmer face plate can be replaced without gap or movement. After installation, confirm the pool cover or other protective system is in place and that the skimmer plug remains seated under cover tension.
Maintenance Tips
- Inspect the plug each time you open the pool for the season; replace if cracks or deformation are visible.
- Ensure no residual water or ice is forcing the plug out of position during freezing conditions.
- Store the plug indoors during the open-season when it is removed to prevent UV damage or warping.
