water running but wont run hot through the kitchen only
This sounds like the cartridge inside of the sink faucet has failed. Some cartridges have a special mixing valve that reacts to changes in pressure to prevent large temperature swings when, for example, a toilet is flushed. If this is the case, you'd have a single handle faucet, and if you disconnected the hot water from the shutoff under the sink, you should have full water pressure when you open that shutoff valve (into a large bucket). To fix it, get a replacement that specific to your faucet and follow the instructions that comes with the replacement. When disassembling a faucet, it's a good idea to place something (usually a towel) in the drain to prevent any lost parts.
