warranty is worthless, due to no customer service
the cartridge in my 6 year old shower faucet began leaking, and when I called Delta the sent me a replacement kit with o rings and springs. After install, it still did not fix the issue. I have tried calling, with no answer, being on hold for over a half an hour, and have sent in 4 emails, with no responses. Now, my second shower is failing too. I will never buy another Delta faucet again. Their warranty is worthless as their customer service is HORRIBLE!
