We have good cold water pressure, but no hot water pressure in bathroom sink and kitchen. The shower has good hot & cold water pressure. What could be the problem. The water in in the hotwater heater drain is clear.

Thanks,WK

Chances are that some crud got into the hot water inlet ports of the cartridge. The solution would be to shut the water off to the faucets and open them up. Check and clean the inlet ports on the cartridges. Before you reassemble turn the water back on for a few seconds to flush out the supplies and open valve bodies. Good luck, Tom
