Installed new kitchen faucett (same as previous faucet). Now it takes forever to get hot water in the kitchen. If I turn off the cold water valve then I can get hot water. Sometimes I can have cold water valve open and get hot water.

More information, please tell us the brand and the model number of your faucet, Thanks.

As a diagnostic measure.

Turn off stop valves under the sink.
Move hot supply tube to cold line, move cold supply tube to hot line.
