I have a kohler a112.181 faucet.. I am experiencing very little water pressure and a slight leak. In faucet handle. The sprayer seems to work ok. I need to know how to take faucet apart to find problem and fix. Any help?

Check to be sure the hose isn't kinked somewhere below the faucet. If there aren't any kinks there is likely debris stuck behind the nozle screen, remove it and clean it- or your handle mechanism is broken. Replacement handles and hoses are fairly inexpensive if you need one they're easy to find at most big hardware stores or on Amazon

you have an other part that went bad. Inside the faucet there ins a part called a devertot that is in the body of the faucet. This little part move the water from the main spout to the hand held sprayer.

You have to remove the handle and the spout. pop it out pop a new one in and you are good to go.

Clean the aerator and I think that will do it.

The aerator is at the end of the spout where the water comes out it just screws off.

First thing to check is if it has a strainer on the spout that has debris. The second thing is if you have a sprayer attachment the diverter valve is a chronic problem with kitchen faucets.

No the length doesn't matter. When you turn the faucet on, you also fill the hose to the sprayer, and it may expand slightly, causing the sprayer to move a little. Is the drip from the end of the spout at the aearator? or is it around the faucet lever. If it is the lever, you should be able to tighten it slightly. If it's the end, make sure your aearator is clean.

Verify the cold water outlet has equal pressure as the hot side outlet at the wall. Check the inlet screen on the cold side water line where it attatches to cold water pipe. The screen could be plugged. Then check the cold side hose for any restrictions. Also check if there is a screen on the outlet side of the cold water hose and see if it is plugged. Otherwise the faucet valve is mis-aligned and will need to be rotated and re-tightened to align the valve to the center so both sides have equal water flow.

there is always water pressure on the sprayer when water is on. if sprayer is leaking check if trigger is stuck in . best to just change the sprayer handle it comes off at the base of the handle

although it is possible that the spray head has gone bad, it is more likely that the diverter mechanism inside the kitchen faucet needs replaced. When this part is defective, it allows full pressure from the faucet to go to sprayer head even though the sprayer is not triggered. The sprayer is not designed to handle full pressure when it is not spraying.

sounds like sticky diverter should replace it
