I've run into a problem that I'm hoping someone can help me solve. I made a last minute decision to order an autofill for our new pool. Pentair T-40. The problem is that my pool deck will 3.5" thick and the autofill cover ring doesn't extend up that high. I ordered some extension collars for the two pentair skimmers but they don't make one for the autofill. Pentair suggested I use a vanishing edge auto fill instead since it has a taller neck. The problem is that I can't get it in time. Their shooting the pool on Thursday and the couple of places I talked to don't stock it. Here's a quick drawing I did to illustrate the problem. Has anyone dealt with a similar issue?
