Skimmer Basket

[smokey]

I have an older (25+) in ground pool that uses the skimmer basket to adjust the amount of return from the skimmer or the main drain.
I had to replace the basket last week (the old one just started to disintigrate) and now I can't adjust the basket (by turning) to get any return from the main drain (I have checked the main drain and it is open).
The basket LOOKS the same (although maybe slightly (1/16 of an inch shallower). I have checked everywhere and the basket sold by pool stores and on line is the only thing available.
Anyone had this basket problem????????????????
