## Questions & Answers

**Q: Ordered this part after plumber reccomendation.  It fixed our leak in November of 2021 and is now leaking again.  Trying to replace for new one.**
A: I had the same issue. It worked for a month. I bought another and the same thing happened. I eventually bought the Kohler replacement part (new design - it doesn't look like the old part) and no leaks. You get what you pay for.
