Check the under-sink hot water shut off valve to make sure that it is fully on. How old is your water heater? Many heaters bulit during the middle 90s are having problems with deteriorating dip tubes which when they go, they crumble into small bits which often clog faucets. Just for grins, remove your aireator. Is there any light colored crumbly trash caught there? If so, that is a very good (or bad) sign that you are having this problem. If that is the case, you can sometimes replace the dip tube (inexpensive item)assuming that you have adequate overhead clearance to remove it from the water heater. Check back with more details. Have you noticed any reduction in the amount of hot water you have available for showers, bathing, etc?
