Things You'll Need
Slip joint pliers
A pull-out kitchen faucet has a sprayer head that can be detached from the end of the faucet body. The sprayer head is on a length of hose and is convenient for spraying larger items that will not fit under the faucet. The hose and fittings on the sprayer head sometimes can develop leaks and cause problems. This situation can be remedied with the purchase and installation of a replacement hose.
Locate and shutoff the water valves under the kitchen sink. If there are not individual shutoff valves under the sink, then the main water shutoff for the house will have to be used to stop the flow of water to the faucet.
Use an adjustable wrench to remove the end of the sprayer hose that is connected to the faucet stem under the sink.
Use a pair of slip joint pliers to remove the sprayer hose from the sprayer head. Pull the hose up through the faucet body and take it to the hardware or home improvement store when you purchase the replacement hose.
Screw the end of the replacement hose with the collar onto the sprayer head. Use a pair of slip joint pliers to tighten the collar but ensure that you do not over tighten it or it could crack.
Feed the other end of the hose through the faucet body.
Attach the end of the replacement hose under the sink to the faucet stem where the old hose was removed. Tighten the fitting with an adjustable wrench. Turn on the water supply using the water valves.
