Step-by-step guide on how to repair a single handle kitchen faucet with a spray hose
If Water Pressure is Too Low
First, make sure the water lever is turned off of the faucet. Then, take the adjustable wrench to open the aerator of your faucet head. When you open the aerator, you may find debris and minerals are built up to cover the water flow. Sometimes, simple washing with water can remove the debris. If the minerals and debris do not go away from the water splashing.
Use 50:50 water and CLR formula and submerge the airhead in the formula for 2 minutes. The CLR will eat the debris and minerals. After that, wash the aerator and place it in the faucet head. Then, tight the aerator with the adjustable wrench. Now turn on the lever to check the water pressure. You will find how simple the pressure issue is gone.
If there are Drips and Leaks
Single-lever faucets will drip if the cartridge or the O-ring is damaged. To replace either part you have to disassemble the faucet. The O-ring is a round piece of rubber installed on the cartridge. Replacing cracked O-rings, which you can find at most hardware stores, should fix a dripping faucet, but if the cartridge itself is cracked or worn, this can cause dripping or leaking at the base of the faucet. Find faucet cartridges at your hardware store or order a replacement directly from the faucet manufacturer.
If the Handle is Closing by Itself
Important Tip
Before doing anything, try to tighten the screw under the cover of the handle that holds the handle on. Sometimes this will solve the problem.
Step:1 Remove the handle
Most faucets have a metal or plastic cover that sits in the center of the faucet. Slip a thin screwdriver or knife blade under this cover and pull it out. under the cover, there is a screw that you have removed. The handle will then slip off the stem.
Step: 2 Use the plumber’s tape to wrap
Wrap plumber’s tape clockwise around the stem. You can trim the tape with a knife so that it fits over the stem without overlapping. Try one wrap at a time. Then place the handle back on and check whether it fits. Until the handle fits, continue wrapping and testing.
Step: 3 Install the handle:
When you see the handle fits, place the handle to its place in the faucet and tighten the screw and set the screw firmly.
If the Handle is Stiff:
Step 1: Shut Off The Water Supply And Cover The Drains
Before you do any work on the faucet, make sure the water is turned off. Then cover the drain area, so that small parts do not run to the pipes.
Step 2: Remove The Handle
Use an Allen wrench to loosen the set screw on the front of your faucet. Then you have to pull up the handle to remove it from the base.
Step 3: Submerged under vinegar
Place the removed handle on a bowl. Pour vinegar on the bowl until the handle is submerged in the vinegar. Keep the handle in the vinegar overnight.
Step: 4 Clean thoroughly
In the morning thoroughly lubricate the facet valve with Plumber’s Grease. For reference, the faucet valve is attached to the base of your faucet.
Step 5: Reinstall
Remove faucet handles from vinegar, clean with water, then dry thoroughly, and re-install the faucet. Now you will see the handle will be as smooth as new!
If the Temperature-control is not working
This could be caused by a problem in the pressure-balance mixing valve or a defective cartridge. To fix the pressure balance mixing valve, follow the steps below,
Step 1: Remove the handle
Remove the handle by unscrewing the nut under or behind the lever with a 1/8-inch hex wrench. You have to pry off a small-cap with a flat-head screwdriver to get to the nut.
Step 2: Gain access to the cartridge
Unscrew the chrome bonnet covering the valve mechanism. You can do it by gripping the chrome bonnet with a rubber glove and turning it counterclockwise.
Step 3: Remove the old cartridge
Unscrew the holding nut that is holding the cartridge in place with adjustable pliers. Then, pull out the cartridge.
Step 4: Replace with a new cartridge
Remove the rubber seal with a flat-headed screwdriver and replace it with a new one. You can find cartridges from a plumber store or you can order from the manufacturer of the faucet.
Step 5: Reassemble
Push the cartridge back into the valve housing. Then, screw on the retaining nut, and tighten it with the pliers.
If you are still having temperature control issues, it means that the faucet has a problem with the pressure balance mixing valves. Follow the steps below to solve this problem,
Step 1: Turn the Hot and Cold Water Valves Off
While doing the work, to avoid any water disaster in the kitchen, turn off both the hot and cold water valves. For most of the faucets, there is a knob to turn the water off. For some of the models, you will have to use the adjustable wrench.
Step 2: Remove the Handle from the Faucet
The handle is held in place on the faucet by a screw which you’ll need to remove. The screw may be placed towards the back or side of the handle. Some faucets have a screw beneath the hot/cold water indicator which can be seen from the front. Find the screw on your particular faucet.
After you find the screw, use an Allen wrench to rotate and remove the screw. Now you can lift the faucet handle from the rest of the faucet.
On some faucet models, you have to twist and turn the front or back of the handle to unscrew it from the main handle’s frame.
Step 3: Adjust the Temperature on the Valve
Once you remove the handle, you will find the temperature valve. Most of the faucets have a valve to move towards the right side.
Step 4: Replace the Handle and Test the Water Temperature
Use a thermometer to check the water temperature. If it is below 120° F, then it is okay. If the water is still too hot, repeat the steps again and retest the water temperature.
