I am having the same problems as many other customers with the strainer basket when reading their reviews!!  I  am now on my 2nd strainer basket in 3 years! Actually the first one came apart about a year after being installed and I fooled around with it re-screwing/tightening, even gorilla glueing it back together!! I finally got sick of fighting it and bought a new basket hoping that mine maybe just had a flaw..... Lo and behold same thing has happened after about 2 months use! Obviously poorly designed! Now what do I do, I don't think any other basket strainer would fit in drain!
