Low water flow may be the result of a shutoff valve that isn't open all the way. An insufficient flow of water is usually the result of a blockage, and to remove it, you first have to locate it. A common cause of blockages in kitchen faucets is a build-up of mineral deposits, which can collect in the supply hose, the shutoff valve under the sink or the faucet valve. Single-handle faucets can have either a cartridge or ball valve, and both types of valves have ports that can get blocked. A good strategy for diagnosing low hot water flow is to begin looking for problems at the water heater and work toward the faucet valve. Make sure that the hot water outlet valve on the water heater is open all the way by turning it counterclockwise as far as it will go. Check the hot water flow in other faucets in the house. If they also have low flow, and the water heater valve is open, there may be a restriction in the pipes near the water heater. This is more likely if the pipes are galvanized steel and old.

The solution is to replace the pipes. Open the shutoff valve under the sink all the way, and see if that makes a difference to the faucet flow. If the valve is already open, turn it off and disconnect the faucet supply hose from the faucet with adjustable pliers. Point the hose into the bucket and turn on the valve. If the flow is less than you expect, you probably need to replace the valve or the hose. Service the faucet if you can't find any other reason for the low flow. Start by turning off both shutoff valves under the sink and opening the faucet to relieve water pressure. Remove the faucet handle with a Phillips screwdriver or Allen wrench, depending on how it is attached, and take out the valve. If it's a cartridge faucet, you may have to pull a pin with needle-nose pliers or unscrew a retaining nut with adjustable pliers to get the valve out. If it's a ball-valve faucet, unscrew the collar holding the valve with adjustable pilers, and carefully lift the valve off. Insert a length of bare 12-gauge electrical wire into the hot water inlet port in the valve seat to dislodge any deposits that may have accumulated there.

Flush the inlet by turning on the hot water shutoff valve for a few seconds. If you see mineral deposits around the base, you may be able to chip them off with a flathead screwdriver. If not, try dissolving them by soaking the valve overnight in white vinegar. Replace the valve if you can't clean it. Reassemble the faucet after cleaning the valve seat and cleaning or replacing the valve. Turn on the shutoff valves, and flush air and loose debris out of the lines by leaving the faucet open for about 30 seconds. A common problem in a kitchen faucet is low water pressure. Low water pressure in a kitchen faucet can be caused by clogs, corrosion in the pipes, or delivery pressure from the main source. Identifying the problem will help greatly in the actual repair, making it fairly easy if the troubleshooting is done properly.
