How to Replace a Kitchen Sink Sprayer (Side Spray or Pull-Down)

How to replace a kitchen sink sprayer depends on the type: a side sprayer swaps through the sink deck and one hose nut, while a pull-down head unthreads or unclips from its hose in about four moves.

Which kind of kitchen sink sprayer do you have?

You have one of two setups. A side sprayer sits in its own hole in the sink deck, with a hose that drops through the deck and screws or clips onto an outlet under the faucet body. A pull-down or pull-out sprayer is the spout itself, a wand on a hose that runs through the faucet and hangs in a loop under the sink with a weight on it. That weight on the hose can also cause a pull-down faucet not retracting properly, a separate headache worth troubleshooting on its own; see pull-down faucet retraction problems.

A side sprayer is a near-universal part. A pull-down head is brand-specific and bought by the faucet’s model number. If you are not sure which design you own, our guide to the main faucet types shows each one.

Find the model number before you shop. Check the original box, receipt or install sheet. Moen, Delta and Kohler organize their parts pages by that number, not by the look of the head.

What part do you buy to replace a kitchen sink sprayer?

Buy by connection, not by looks. An older side sprayer that screws onto a threaded nipple takes a universal kit. A Moen faucet with a Duralock quick connect takes a Moen part. A pull-down head needs the maker’s part for your faucet series, because hose ends, spray modes and docking magnets differ even inside one brand.

Prices are October 2026 listings and move often. The Delta Trinsic assembly costs about seven times the cheapest universal side sprayer.

How do you replace a side sprayer on a kitchen sink?

Shut off both supply stops, disconnect the old hose from the outlet under the faucet, remove the mounting nut that holds the sprayer base, then set the new base on a 1/4-inch bead of plumber’s putty, tighten its nut from below and thread the new hose on finger-tight. The whole job is seven steps with a basin wrench and pliers.

1. Turn the hot and cold stop valves under the sink clockwise until they stop, as This Old House directs, then open the faucet and squeeze the sprayer to drain the lines.
2. Follow the sprayer hose up to where it joins the faucet. A threaded nut unscrews counterclockwise, by hand or with an adjustable wrench. A quick connect releases at its collar or clip.
3. Pull the old hose up and out through the sprayer base from above the sink.
4. Loosen the mounting nut under the base with a basin wrench or slip-joint pliers, lift the base out and scrape off the old putty.
5. Roll a 1/4-inch bead of plumber’s putty under the new base, per Home Depot’s guide, and drop its tailpiece through the hole.
6. From below, slip on the friction washer, spin on the mounting nut and tighten it with the basin wrench while a helper keeps the base square.
7. Feed the new hose down through the base, screw it onto the faucet’s hose nipple with your fingers (or snap it into the quick connect), restore water and check every joint for drips.

Go easy on the last turn. Home Depot warns that overtightening the hose nut can crack plastic parts. If only the hose leaks and the head works, Ace lists a Danco 48-inch replacement hose alone at $7.99.

How do you replace a pull-down or pull-out sprayer head?

Pull the wand out, keep the hose from snapping back into the spout, then release the old head from the hose end and attach the new one. Delta says the Trinsic Pro head threads on with a 1/2-inch connection. Noel’s listing for Moen’s 173137SRS head says it uses Moen’s Duralock quick connect. You only go under the sink if the hose itself is bad.

1. Pull the wand out to full length and clip a clothespin or spring clamp onto the hose just below the spout so it cannot retract.
2. On a threaded head, turn the head counterclockwise off the hose. On a clip or quick connect head, slide the clip out or release the connector and pull the head straight off.
3. Check the hose end. Delta says its wand can be removed from the hose so you can check the debris screen on the back for sediment. Rinse any grit out and confirm the washer or O-ring is seated.
4. Point the open hose into a bucket and run water for a few seconds to flush loose debris before the new head goes on.
5. Thread the new head on hand-tight, or push it onto the connector until the clip seats, then tug to confirm it holds.
6. Remove the clamp, let the weight pull the hose back and test every spray mode with the water on.

A full hose swap is a bigger job. A Delta answer on its RP51480 page says you may need to remove the spout arm, run the hose through the spout and then down the faucet body. One Delta owner described removing the clip between the hose and the water line under the sink. Move the old weight to the new hose before you reconnect it.

Why is my kitchen sink sprayer not working or spraying weak?

A weak or dead kitchen sink sprayer is usually a clogged head, a blocked debris screen at the hose end, or on a side sprayer, a fouled diverter. Test in order. Remove the head and run water. Strong flow from the bare hose means the head is clogged. Weak flow means the hose or diverter is the problem.

• Clogged head or aerator. Soak it in white vinegar to dissolve scale, as This Old House advises. Delta sells an aerator wrench, RP52217, for heads with a removable aerator.
• Blocked screen. Pull-down heads often hide a debris screen where the head meets the hose. Delta points owners there first.
• Bad diverter (side sprayers). The diverter sits under a decorative cap on the faucet body. This Old House says it unscrews with a quarter and has 8 to 10 threads, and recommends a new one over cleaning.
• Kinked or plugged hose. Disconnect both ends, run water through and clear it with a flexible brush or thin wire.
• Stuck check valve. Some Moen pull-downs use a check valve kit (158550, $6.12 on Moen’s Jaslynn parts list).
• Low house pressure. This Old House says static pressure should read 40 to 60 psi on a gauge at a hose bib. Below that, no sprayer will perform.

Where does the counterweight go on a pull-down sprayer hose?

The weight sits on the hose loop under the sink so gravity pulls the wand back into the spout, and the exact spot depends on the faucet. Moen INS2049F puts it just above the start of the loop curve, at a locator mark on the hose. Moen INS10676B, for a spring pulldown, puts it in the bottom of the loop curve. Kohler 1281441 puts it about 11 inches (279 mm) from the bottom of the hose loop, and Delta 44954 Rev. A asks for a minimum of 14 inches (356 mm) below the connection to the valve. Delta says its RP80523 weight slides directly onto the hose and that more weights can be added. If the head will not retract, the weight has usually slid out of position or is snagging on the trap.

Place it where your faucet’s installation sheet shows, then pull the wand out to full reach and watch the loop. The weight should rise freely without touching the P-trap, disposal or anything stored in the cabinet, and drop back when you let go. Delta’s RP80523 is about 2 inches across and 1-5/8 inches tall, so give it room.

Lost or broken weights are sold separately. Moen lists the 125989 hose weight at $26.00, and Delta lists the RP80523 at $42.72 online. Moen’s Jaslynn uses a 68-inch hose and Delta quotes 54 inches for the Trinsic Pro, while Delta’s Leland 9178 page lists a 20-inch retractable hose.

When should you replace the whole faucet instead of the sprayer?

Replace the faucet when the sprayer part costs a large share of a new faucet, when the faucet body itself leaks, or when the maker no longer sells the part. Delta lists its Leland RP51480 spray assembly at $175.12 online, and Delta says its pull-down wands cannot be repaired, only replaced whole.

Compare that against a new faucet before you order. Our guide to the cost to replace a kitchen faucet lays out typical fixture and labor prices, and if you go that route, follow our steps on how to replace a kitchen faucet.

Call a plumber if the supply stops will not shut fully, if a compression nut on a stop is corroded, or if the faucet mounts through a stone top where you cannot reach the nuts. Those are the cases where a $25 part turns into a cabinet flood.
