My pool was built in the late 70's. Im the second homeowner. Here is a picture of the inside of my skimmer. pool skimmer.jpg
I had (and have misplaced) the flat plastic disk (about a 1/4 inch thick) that fit down into the skimmer blocking the skimmer flow allowing flow from the main drain to the filter. I purchased one of these diverters, but it is about a 1/2 inch too small in circumference and also does not fit down properly as that circular "knob" in the 1st picture at the top is raised above the shelf the diverter would sit.
Ive been to several pool stores looking for a replacement disk but the only thing they carry are these "UFO looking" diverters.
THE QUESTION-Can someone lead me to the old school diverter disk that will allow me to pull flow from my main drain. THANKS!
