Hi Binkies,
Thanks so much for your review.
We're sorry to hear about your experience with the drain and want to do anything we can to assist.
From what it sounds like, this may have been an installation issue - we would love to go over the installation with you directly and also ensure you have any and all parts you need to have your faucet and drain performing beautifully.
We also have replacement parts for all of our products if they are ever needed.
I went ahead and opened a case for you with our Customer Service Team: Case 108517.
Please reach out to our Customer Service team via email at customerservice@kraususa.com and we will take it from there!
Thanks for reaching out and we hope to hear from you soon.
