My pressure is reduced only on my hot water in the kitchen sink, I have a Delta Single lever faucet. We've been here about 2 years and all worked fine until a few months ago, it appears to be fairly new plumbing (about 6 to 8 years old) How do I repair this problem.
Thank You.

Shut the water off and open up the faucet,(see image) remove everything through the seats and springs. Clean our any crud you might see and then place a pan over the upon faucet ant turn on the hot water to flush out the hot water supply. Good luck, Tom

Hot water builds up scaleing do u drain your hot water heater as it should be drained every few months to eleminate scaleing. If u are on well and septic remove the anode rod
