Step by step instructions

This is dry reading. But read the whole thing first. Then begin your project. This is how we repair faucets near you.

  1. Shut the water off. If you don’t have faucet water shutoffs or you do and they’re scary looking, just shut the water off to your whole house.
  2. Plug the sink drain so no loose parts fall down the drain.
  3. Remove the single handle. If you have a crystal handle you’ll have to pry the index button out of the middle of the handle with your screwdriver. Then remove the handle screw and then the handle. If you have a brass lever handle use the allen wrench end of the Delta faucet wrench that comes in your RP3614 repair kit to remove the allen screw at the base of the handle and wiggle it off.
  4. Remove the bonnet nut. (The dome shaped cap.) You’ll use your pliers for this. If the bonnet nut is seized, very common problem, use penetrating oil, CLR, WD40 or just a lot of elbow grease to remove it. If you still can’t get it off I’ve gently sawed the cap at it’s base and popped it open with a flat head screwdriver. But it may be easier to just replace the faucet at this point.
  5. Remove the cam and packing and ball assembly.
  6. Using the slightly angled pick remove the rubber seats and springs inside the base of the faucet.
  7. If there are any hard water deposits use your sandcloth mesh to rubbed them off. Don’t use a pick or screwdriver. You can mar the housing making it impossible to seal correctly.
  8. Lubricate the inside of the faucet housing and threads with your plumbers grease.
  9. Lubricate the new rubber seats in your handle repair kit. This will prevent cracking and allow for a better seal.
  10. Put the smaller end of each conical spring inside each rubber seat. Then put your straight pick through the top of the rubber seat and spring. Using the pick as a guide, place the end of the pick inside each seat orifice inside the faucet and slide the seat and spring in place while pulling the pick out. You may need to work it in place with your finger until it pops in place.
  11. If the old ball assembly has a straight shaft then you’ll be using the triangular cam. If it has a triangular shaft you’ll use the cam with the straight groove. Just look at your old parts. If you’re reusing your old ball assembly gently scrub any hard water deposits off with your sandcloth mesh and lubricate it with your plumbers grease. Place the ball assembly into the housing being sure to match the groove in the side of the ball assembly with the little nub on the interior housing of the faucet.
  12. Lubricate the cam and packing with your plumbers grease. Put them together and place them on top of the ball assembly. Be sure to match up the nub on the outside of the cam with the groove on the edge of the faucet housing.
  13. Put one finger through the bonnet nut and use the same finger to push and hold down the cam and packing while threading the bonnet nut on with your other hand. Try it a couple of times. You’ll get it.
  14. Reassemble handle. Turn the water back on. Test for leaks. If the cam and packing leaks at all use the Delta wrench with the 2 prongs to thread the top of the cam clockwise a little.

Delta single handle kitchen faucet vegetable sprayer

If it’s a kitchen faucet you’re repairing you may find that the vegetable sprayer isn’t working correctly. It will often get jammed up with hard water or the the rubber seals will get stuck. For this repair we’ll just dive into the middle of the previous instructions.

Before beginning step 6 you’ll want to wiggle the whole kitchen spout off the faucet housing. You’ll need to rotate it back and forth while pulling up. You’ll see two o-rings around the exterior of the faucet housing. Using your angled pick remove them. Then you’ll see a round plastic stem near the base of the front of the faucet housing. This is the diverter valve. I use needle nose pliers or my pick set to remove the old one. If there’s any hard water deposits use your sandcloth mesh to remove them. Lubricate the opening with heat proof grease. Lubricate the new diverter valve (Delta RP63136 diverter valve) Press the new valve into the faucet. Lubricate the two large o-rings and install them in the appropriate spots on the shaft. Clean and lubricate the inside of the faucet spout housing and slide it back onto the faucet housing. Then proceed to step 6 above.
