My kitchen faucet is a Delta. Last Friday the hot water side would not shut completely off, so being a long holiday weekend I just shut off the valve under the sink until I decided what to do and limped through the weekend. This morning I finally had an open schedule and decided to look it up on line to see if I could replace the innards myself . .....and I did it! While I was at it, I went ahead and replaced the hot and the cold sides. Once I figured it out with the help of on line instructions and a little advice from the man at the plumbing supply store, it was easy schmeesy! No more leaky faucet.....yeaaaaaa! Go me!
