Water leaks from around the stem when I lift the water handle. What to do? It doesn't drip from the tap, but from around the stem part - sometimes quite a lot of water. Can I repair this myself? It's a Moen single lever kitchen faucet.

Hi Cindy you don't say where it leaking from so:
If you have a dripping that won't completely turn off then the stem washer needs replacing. If it is leaking at the handle then the "O" ring is bad.
I suggest you just replace both.

Under your sink turn off the two water supply knobs
remove the handle. Either a screw on top or and allen screw under and on the side then pry up. this maybe hard so wiggle it.
now take a crescent wrench and unscrew the stem
you see a washer screwed to the bottom. Most likely a "OO" size and a rubber "O" ring around the stem.
Take it the stem to your hardware store and have the give you a repair kit. very cheap
replace both and reinstall.
I it has 2 handles do both sides
Its easy.

Hope this helps Mike

1. • Test the dripping water with your hand to make sure that it is the hot water side that is leaking. Lay a rag over the sink drain to keep parts from falling down it. Locate the hot and cold shutoff valves under the sink and turn the knobs clockwise by hand until they close. If the knobs remain stiff, use a pair of pliers to gently turn them until the knob begins to move, then finish turning by hand.

     Pry the decorative cap off the faucet top with a small thin, flat-head screwdriver. Remove the cap that has the "H" letter on it. Depending upon the handle screw configuration, use a flat-head or Phillips-head screwdriver to remove the handle screw. Gently pry up on the handle from all angles and pull it up and off the splines of the stem.

     Use a crescent wrench to turn the hot water stem nut counterclockwise until it comes completely off the stem shaft. Wiggle the stem with your fingers and pull it out of the faucet. If the washer on the bottom of the stem is deformed, it indicates the source of the leak. However, remove the old seat from the faucet base with an Allen wrench or a seat removal tool.

     Wipe out the inside of the seat housing with a rag. Replace the seat with the new one included in the repair package, using an Allen wrench or seat removal tool.

     Place the new hot water stem shaft into the valve seat, and start the stem nut in by hand, turning it clockwise. Finish tightening the stem nut with the crescent wrench, but only to a moderate firmness -- do not over-tighten it. Place the handle back over the stem shaft and tap it down until it seats firmly. Replace the handle screw and tighten it with a screwdriver.

     Turn the hot and cold water supply knobs counterclockwise until they are fully open. Turn the hot water faucet knob to the "On" position and check for leaks.
     

your video doesn't show much of your shower for very long, but at a guess i'd say you have separate hot cold taps, in which case always turn on hot first then carefully turn on cold to ensure there's no issue with water pressure. if there no hot water running at all the hot water valve is faulty

this could be abad tap washer
a faulty loose pipe connection
or a faulty tap
turn of your water supply at the outside your house before proceeding
remove the handle on your tap then remove insert screw valve usually with a spanner or shifter
you should see a copper or plastic stem inside with a flat washer at the end which

There is normally a plastic washer at the end of the valve stem which you turn to allow the water to flow and to stop the flow. It sounds like this washer has either deteriorated or been damaged by over-tightening. You will need to remove the stem and replace this washer. It is normally held in place with a screw.

You will need to remove the on-off handle and probably a stem cover to access the flats on the stem where you can place a wrench. These flats will likely be recessed into the shower wall; therefore, it will likely require a deep socket to reach them. Most hardware stores will have the sockets needed to remove and replace these stems.

Of course, make sure that the main house shutoff valve is closed before you start to do this.

dependent on the type of faucet, you need to replace (a) the washers, (b.) the spring and seals or (c.) the gasket. They all serve the same purpose. 1. turn off the water supply to the faucet. 2. double handle? (a)remove the center cap (b) then remove the screw holding the handle down (c)next unscrew the valve stem retaining nut (normally it is the one right above the faucet body). (d) pull the valve stem out, if there is a small rubber piece held down by screw remove the screw, replace the washer. if there is a rubber gasket wrapped around the stem, remove and replace it, if nothing is on the stem look into the faucet body you should see 1 or 2 small rubber pieces these are the seals the springs are right below the seals. Remove and replace springs and seals. 3. single handle? remove the handle retaining screw, normally covered by hot/cold indicator symbol, unscrew valve stem retaining nut, pull the valve stem and replace either the gasket or springs and seals.

the whole faucet is bad it has an internal leak replace the whole thing

turn off main water in home . turn on tap some where in home to release presser take shower handle off (screw under cap) unscrew the tap with a wrench unscrew on insides you pull out replace washer put all back togethere

I am assuming that your kitchen tap is leaking through the spout

if it is single lever you will need to remove the crown and spout by removing a small erasure size cap on the housing right under the spout or up near the back of the ever then use a hex wrench to remove the set screw( plug the drain holes do it does not go down the drain)

turn the water off (hot and cold ) under the sink
remove the set screw and lift off the lever

at his point you can take an adjustible wrench(channel lock and tighten the big ring nut that holds the cartridge in place

temorairly put the handle back on and put the handle in the off position turn the water on under the sink and see if it stopped leaking

if it still leaks you have to turn the water back off and remove the lock nut then the cartridge and go to big box store with old cartridge and name of mfg and get a new one and install

If you have seperate hot and cold valves on top of sink deermne which is leaking by turning one off with oher on undr the sink

once you have determined which it is (hot or cold)
take a phillips head screw driver( remove plastic clear cap on top of faucet handle with sharp crewdriver of knife blade) and remove the screw holdin the handle on to the stem(turn counter clock wise

be sure to turn water of under snk on both faucet risers after removing acrylic handle you then take an adjustible wrench and remove the crown nut turn counter clockwise until it comes off over stem

remove stem( looks like size of a pretzel about six inches long with washers on side and one on end

take the stem to local hardware(ace) or big box store and go to lumbing section ask clerk to inspect and recommend replacement washers or replacement stem (if needed)

go back reinstall and tighten crown nut snug( open (turn counter clockwise) tem valve before you snug it down with crown nut
install acrykic or chrome handle with brass phillips screw then ut cap on and turn on water and check for leaks

good luck

Hi, it appears you have a defected relief valve. you can try one solution. lift the handle on the relief valve and let some water out. sometimes that can flush out materials thats blocking the stem in the valve. if it's still leaking it must be replace.

If this doesn’t work for you please write back. Thanks,
