If your kitchen faucet spray isn’t working as well as it has in the past, chances are the problem with the sprayer is fairly easy to fix. Before you grab the phone and call a plumber, go over these simple suggestions to see if you can fix it yourself.
Check for Kinks
First check the hose. Pull the kitchen sprayer out as far as you can. Check carefully for any kinks or small holes. Even a small one can greatly reduce the water flow coming out through the kitchen faucet sprayer. A small hole can cause a slight leak, which can damage your cabinets as well as lower water pressure.
Next check the diverter valve. This is a small part directly under the sprayer nozzle. Turn off the water supply and simply unscrew the end of the kitchen faucet sprayer. Carefully remove the diverter valve with a pair of pliers and check for deposits or gunk build up. You can clean these easily by using mild soap and water. You can also opt to replace this. It’s a cheap part available at most hardware stores.
Check the kitchen sprayer itself for mineral deposits or hard water. This is another common cause for low pressure and dripping.
If these ideas didn’t fix the problem, you may want to call a plumber.
