Faucet requirements?
Is there a special kind of fitting you need for the kitchen faucet to connect the water supply hose to? If so, what kind?
Yes, but the fitting is included. The end that screws on to the faucet is dual-threaded (male and female threads) so it will work with 90% of faucets. However it does not work with most pullout style faucets because they don't have enough threads to create a sealed connection. I had to replace my pullout faucet with a traditional faucet with a side sprayer to make the dishwasher work.
