will missing clip and o-ring cause leak

faucet is leaking out of the bottom of the spray handle and water is running down the hose to the cabinet below
Asked by: don
Yes Don, the O-ring is the most important of the two item. It forms a seal, under pressure between the spray head and the flexible hose. I had the same issue. If the o-ring is split, or not complete, meaning somehow a piece of the ring has been sheared off and the ring is no longer a complete, and full 360* piece of rubber, It will leak. Now if the spray head is left in the goose neck tube. the water will backup into the gooseneck tube and leak up and around the tube and eventually drip out into the cabinet. Remember the extending hose is what is carrying the water. The pretty tube is just a piece that hides the hose. Keeping the spray head out of the tube, for the time being, will allow the leaking water to simply drip into the sink during use.There will be no water leakage once the water is turned off, as the seal at the on off handle will stop the flow of water into the hose and subsequently into the leaking spray head. replace the o-ring by removing the spray head from the hose with a set of pliers, taking care not to pinch the hose itself. There is a knurled area on the spray hose. Loosen the head with the pliers there. Remove the defective o-ring, if it hasn't come off already. Making sure no material from the previous o-ring is in the p-ring groove roll on, or with a very small amount of petroleum jelly, slide the o-ring into the o-ring groove. The o-ring should be tight fitting and flush with the outside of the plastic or metal fitting. The o-ring should not be too loose when in the o-ring groove, as this may indicate the o-ring is too large in diameter, and will have a good chance of being sliced in two when reinstalling the spray head. Next, install the spray head using the same pliers, tightening the spray head to a moderate tightness. Turn on water at handle and check for leaks around the outside of the spray assembly. If none, you are finished. If just a little water is leaking, tightening the spray assembly a bit tighter should solve the problem. If leaking generously, the o-ring may have been damaged during reassembly. The o-ring should the be examined for sheared pieces or damage that caused the whole mess to begin with. If damaged, replace with new o-ring, reassemble and check again. No leaks, you are finished.

How do I replace the O-Ring?

My faucet was leaking and I found the O ring to be broken. The hardware store has various sizes. 1. What size is the O-Ring? 2. Does it fit in the groove near the end of the metal nozzle that plugs into the wand?
Asked by: Ted
Hi Ted, Thank you for your question. The o-ring that comes in RP73984 measures 5/16"ID x 7/16"OD x 1/16" thick. The o-ring does install in the groove near the end of the metal fitting. Thanks, Dave
