My hot water at the kit. Sink is flowing slow. The valves are all working properly. I thought it may be a blocked pipe, but when the dishwasher draws water, the flow at the faucet increases. There is a water hammer arrestor in the line to the dishwasher---could this be affecting the flow to the sink? I'm stumped---HELP!

This turned out being the supply hose from the shut off valve to the sink. It had a anti-flood feature, which was defective.
