All the faucets in my house are Delta. I especially like the look and convenience of my kitchen faucet, the Talbott. Recently it began to leak and I had difficulty turning it off. I purchased a new cartridge (I found out Delta would have sent me a free one) and tried to install it. I couldn’t get the old out, nor could my handyman or plumber. I contacted Delta and within days a new faucet was delivered. I’m thrilled. 
Delta, I’m a loyal customer for life.
