Skimmers
Two methods of installing the swimming pool skimmer with concrete forms:
Method 1 - Pour in Place
Dedicate an interior concrete form, screw holes in face sheet for skimmer, and use a pilaster concrete form on exterior wall. Add a short section of pipe to skimmer ending with a coupling. Coupling should be taped and fit tightly against pilaster.
Method 2 - Block-out
Simply block-out an area to desired dimension using wood or a prefabricated concrete form block-out. After forms are removed, place skimmer in wall and finish installing by using mortar.
