I have been in my house since June 2017 which I purchased new. I am having to replace the pull out hose for the third time. This time the rubber O ring for whatever reason has expanded making it difficult to push the sprayer back into the faucet housing.  The instructions to replace the hose are poorly written. I generally can make what I would call a simple repair, however in this instance I have had to call out a plumber to repair. I have had a number of pull out faucets over the years and the Delta Trinsic is  not a faucet I would ever purchase or recommend anyone else to purchase. To Delta's credit they have been most accommodating in sending me new hoses..
