A weak, dribbling spray or a spray head that won’t retract into the faucet body almost never means you need a new faucet. A kitchen faucet head replacement is one of the simplest plumbing repairs there is, usually finished in 15 minutes with no tools beyond your hands and maybe a pair of pliers. The spray head and its hose take the most abuse of any faucet part, so they wear out first. This guide shows you how to identify the right replacement, swap it, and fix the common problems that make people think their whole faucet has failed.

When the Head Is the Problem
Before you buy anything, confirm the spray head is actually the culprit. Telltale signs point to the head or hose rather than the valve.
- Weak or split spray pattern: usually mineral buildup or a cracked spray face.
- Head won’t dock or keeps drooping: a worn magnet, weight, or hose.
- Leak where the head meets the hose: a failed gasket or stripped threads.
- Head won’t switch between stream and spray: a broken diverter inside the head.
If water instead leaks from the base of the faucet or drips from the spout when off, the problem is inside the valve cartridge, not the head, and replacing the head won’t help.
Pull-Down vs Pull-Out vs Fixed Heads
Match the replacement to your faucet style. A pull-down faucet has a tall gooseneck spout with a head that pulls straight down; a pull-out has a lower spout with a head that pulls toward you on a longer hose. Some older or budget faucets have a fixed spray head threaded onto the end of the spout. Each takes a different replacement, so note which you have before shopping.
Brand matters too. Moen, Delta, Kohler, and Grohe each use their own connection styles, and many offer exact-match replacement heads. A genuine manufacturer head costs $25 to $60, while universal heads run $12 to $30 but require you to verify the thread fit.
Identifying the Thread Size and Connection
The spray head connects to the hose with a threaded coupling. The two most common sizes are M15 x 1 and M18 x 1 metric threads, though some brands use proprietary quick-connect fittings. To find yours, unscrew the old head from the hose and either measure the outer diameter of the male threads with calipers or take the head to a hardware store to match it. Delta faucets frequently use a proprietary hose-to-head connection, so buying a Delta-branded head avoids guesswork.
If your faucet is under warranty, many manufacturers, including Moen and Delta, will ship a replacement spray head free of charge. Have your model number, usually stamped under the spout or printed on the original documentation, ready when you call.
Tools and Materials
- Replacement spray head (matched to brand and thread)
- Adjustable pliers or a strap wrench (only if the connection is stuck)
- A rag to protect finishes and grip wet parts
- Plumber’s tape (for threaded connections that seep)
- White vinegar for cleaning mineral deposits
Step-by-Step Replacement
- Pull the head out. Extend the spray head fully so you have slack in the hose to work with. You usually don’t need to shut off the water for this job, but you can if it makes you comfortable.
- Unscrew the old head. Grip the coupling where the hose meets the head and turn counterclockwise. Hand-tight is common; use pliers with a rag only if it’s stuck.
- Check the weight and gasket. Inspect the rubber gasket or O-ring inside the coupling and the hose weight for wear. Replace the gasket if it’s flattened or torn.
- Thread on the new head. Screw the replacement onto the hose by hand, turning clockwise until snug. Do not overtighten; the gasket does the sealing.
- Test. Run the faucet, cycle between stream and spray, and check for leaks at the connection. Let the head retract to confirm it docks fully.
That’s the whole job. If the head still leaks at the coupling, add a wrap of plumber’s tape to the male threads and reseat it.
Fixing a Weak Spray Without Replacing
Sometimes you don’t need a new head at all. Mineral scale clogs the tiny rubber spray nozzles and the internal aerator. Soak the head overnight in a cup of white vinegar, then scrub the spray face with an old toothbrush and rub the rubber jets with your thumb to dislodge deposits. This restores full flow on most heads and costs nothing. If flow is weak across the whole house, the problem is upstream, not in the head.
Replacing the Hose Too
If the head is fine but the hose leaks or has lost its retraction, the hose weight or the hose itself may need replacing. Pull-down hoses attach under the sink at a quick-connect fitting; disconnect it, feed the new hose down through the spout, and reattach the weight at the same position on the hose so the head retracts cleanly. Replacement hoses run $10 to $25.
Cost and When to Replace the Whole Faucet
A full kitchen faucet head replacement typically costs $12 to $60 in parts and nothing in labor if you do it yourself, versus $200 to $400 for a new faucet installed. Only replace the entire fixture if the valve leaks, the finish is failing across the spout, or you simply want a new style. For a tired sprayer, swapping the head is the fast, frugal fix, and it makes an aging faucet feel new again.
