The right kit depends on your faucet type: a universal O-ring and washer kit for compression faucets, a brand-specific repair kit for ball faucets, and the exact replacement cartridge for cartridge faucets.
A drip is worth fixing promptly: the EPA's WaterSense program says a faucet dripping once per second can waste more than 3,000 gallons a year. The parts are inexpensive, and most repairs need only basic hand tools.
If you haven't done this repair before, the step-by-step process is covered in How to Fix a Leaky Faucet. Every spec below links back to the manufacturer in the Sources list at the end; prices change, so check the current one on the retailer's page.
Quick Picks
| Faucet type | Kit or part | What the maker says it's for | Link |
|---|---|---|---|
| Ball faucet (Delta, Peerless single-handle) | Delta RP3614 Repair Kit | Single-handle faucets using the ball assembly, seats and springs; not for cartridge faucets | Shop Delta RP3614 |
| Cartridge faucet (older Moen single-handle) | Moen 1225 Cartridge | Moen single-handle faucets made before 2009 (date varies by model) | Shop Moen 1225 |
| Compression faucet (two handles that tighten) | Universal washer and O-ring kit | Match each worn washer and O-ring by size | Shop universal kits |
| Any repair with rubber parts | Silicone faucet grease | Lubricating O-rings and washers on reassembly | Shop silicone grease |
For Kohler and other cartridge faucets, find the part by your faucet's model number on the maker's own parts lookup. Cartridges are model-specific, so we don't list a single "best" one.
Best Ball Faucet Kit: Delta RP3614
Delta RP3614 Repair Kit is Delta's own repair kit for single-handle faucets that use a ball assembly with seats and springs.
What's inside, per the product listing:
- RP4993: 2 seats and 2 springs
- RP25: 2 valve-body O-rings
- RP61: lever-handle cam and packing
- RP181: knob-handle cam and packing
- RP1974: 1/8" hex key and adjusting-ring spanner
What it doesn't include: the ball itself. Delta sells the ball assembly separately (for example RP70, the stainless-steel lever-handle ball), so inspect yours and buy one only if it is scored or worn.
Price: Delta listed it at $22.80, with an online price of $18.24, in October 2026.
Not for: faucets controlled by a self-contained cartridge. A Delta answer on the product page says, for example, that the RP3614 will not fit its 11926-SS-DST kitchen faucet, which uses a cartridge. A pull-down like the Delta 9178 also takes a cartridge: see Delta 9178 faucet leaking.
Best Moen Cartridge: Moen 1225
Moen 1225 Cartridge is a water-flow cartridge that sits directly below the handle and controls both volume and temperature. Moen says it is commonly used in its single-handle faucets produced before 2009, with the cutoff varying by style and model. For bathroom faucets Moen lists two variations (360-degree handles on the 4400 and 4500 series, and 180-degree top-mount handles), held in by a U-shaped copper clip.
Installation, per Moen's kitchen-faucet guide: slide the copper clip out of the valve body, rotate the cartridge a quarter turn with the plastic twisting tool, and pull it out by the stem with pliers. Fit the new one with the small notch on the stem facing forward, because the notch sets hot and cold. If hot and cold come out reversed, rotate the stem 180 degrees. Slide the clip back in gently and don't force it.
If it's stuck: Moen publishes a separate guide for a 1200 or 1225 cartridge whose stem came out but whose housing stayed in the valve body.
Check first if: your faucet is newer. Moen ties the 1225 to faucets made before 2009, so confirm by model number before buying. Showers are covered in Moen 1222 vs 1225 cartridge.
Best for Compression Faucets: A Universal Washer and O-Ring Kit
Universal washer and O-ring kits suit older two-handle compression faucets, the style whose handles tighten like a knob at the end of their travel. These faucets seal with a rubber seat washer pressed against a seat, so the repair is replacing the washer and the stem O-ring.
How to use one: take the old washer and O-ring out first and match them against the kit by size, not by guesswork. If nothing in the kit matches, take the old stem to a hardware store.
Best for: older homes with two-handle compression faucets, or a faucet whose brand you can't identify.
Use Silicone Grease on Reassembly, Not Petroleum Grease
Coat new O-rings and washers with a silicone faucet grease before reassembly. Check the label before you buy: not every "plumber's grease" is safe on rubber. Oatey's 1 oz petroleum-based plumber's grease, for example, is labelled "Not for use on rubber or synthetic O-Rings."
Which Kit Do You Need?
Step 1: Identify your faucet type.
- Single handle that rotates in a sphere? → Ball faucet
- Single or double handle with a smooth, controlled feel? → Cartridge faucet
- Two handles that physically tighten like a knob? → Compression faucet
Step 2: Find the brand and model number.
- Look under the sink for the faucet box or installation guide
- Look for a brand logo on the faucet body or handle cap
- If none of the above, take the old part to the store and match it
Step 3: Match the kit to your brand and faucet type.
- Delta/Peerless single-handle ball → Delta RP3614 (plus a ball only if yours is worn)
- Moen single-handle, made before 2009 → often the Moen 1225; confirm by model number
- Kohler or any other cartridge faucet → the cartridge listed for your model on the maker's parts lookup
- Two-handle compression → universal washer and O-ring kit

Frequently Asked Questions
- What is the best faucet repair kit?
- It depends on the faucet type. For a Delta or Peerless single-handle ball faucet, Delta's RP3614 kit replaces the seats, springs, cams and body O-rings. For a cartridge faucet, buy the exact cartridge for your model: Moen lists the 1225 for many of its single-handle faucets made before 2009. For an older two-handle compression faucet, a universal washer and O-ring kit lets you match the worn parts by size.
- How much does it cost to fix a dripping faucet yourself?
- The parts are the cheap part: Delta's own online price for the RP3614 ball-faucet kit was $18.24 in October 2026. What a plumber charges varies by area, so get a local quote to compare. Most repairs need only a screwdriver, a hex key or adjustable wrench, and the kit.
- What is in a faucet repair kit?
- It depends on the kit. Universal kits for compression faucets are assortments of O-rings and seat washers. Delta's RP3614 ball-faucet kit contains two seats and two springs, two valve-body O-rings, a lever-handle cam and packing, a knob-handle cam and packing, and a hex key with an adjusting-ring spanner. It does not include the ball. For a cartridge faucet, the 'kit' is simply the replacement cartridge for your model.
- Can I fix a ball faucet without a repair kit?
- Technically yes, but you would have to identify and match several small seats, springs and O-rings separately. A brand-specific kit such as Delta's RP3614 packages the matching wear parts together, which is faster and less likely to mean a second trip to the store.
- What causes a faucet to drip?
- Most drips come from a worn rubber washer or O-ring that no longer seals the water flow when the handle is turned off. In ball faucets, worn springs and seats also cause drips. Cartridge faucets drip when the cartridge degrades. All of these are inexpensive parts compared with a new faucet.
- Do I need a faucet repair kit or a replacement cartridge?
- It depends on the faucet type. Ball and compression faucets wear out at the O-rings, seat washers, and springs, so a repair kit replaces those individual parts. Cartridge faucets have no serviceable internals — the cartridge is a sealed unit, so the repair is swapping the whole cartridge for one that matches your faucet's model number. If the single handle rotates in a sphere, buy a ball repair kit. If it moves smoothly on a pivot, buy the cartridge.
- How do I use a universal faucet repair kit step by step?
- Shut off the supply valves under the sink and open the faucet to drain the line. Plug the drain so small parts can't fall in. Remove the handle (usually one screw under a decorative cap), then lift out the stem or ball assembly. Match each worn O-ring, washer, and spring against the kit by size rather than by guesswork. Coat the new rubber parts with silicone plumber's grease, reassemble in reverse order, then reopen the valves slowly and check for drips.
- Do Delta faucet repair kits work on Peerless faucets?
- Often, but confirm the model before buying. Peerless is a Delta Faucet Company brand, and many Peerless single-handle faucets use the same ball-valve design as Delta's, which is why the RP3614 kit is commonly sold as fitting both. It is not universal — Peerless also makes cartridge models that a ball kit will not fit. Find your faucet's model number and check it against the manufacturer's parts lookup first.
- Moen 1225 or 1200 cartridge — which one do I need?
- Both are Moen single-handle flow cartridges, and Moen covers them together in its guide to removing a stuck cartridge. Neither is a two-handle part, so if your faucet has two handles you need a different component entirely. Moen says the 1225 is commonly used in single-handle faucets made before 2009, so look yours up by model number on Moen's cartridge pages rather than guessing from the handle style.
- What repair kit do I need for a two-handle bathroom faucet?
- Two handles almost always means a compression or two-stem cartridge faucet, not a ball faucet — each handle controls its own valve. For compression faucets (handles that tighten like a knob at the end of travel), a universal O-ring and seat-washer kit covers most North American models. For two-handle cartridge faucets you need two stem cartridges matched to the brand. If you cannot identify the faucet, take one of the old stems to the hardware store and match it there.
- Can a faucet repair kit fix a dripping bathtub faucet?
- Yes — tub and shower valves use the same washer, seat, and cartridge designs as sink faucets, so the drip usually has the same cause and the same fix. The difference is access: the valve sits behind the wall, so you have to pull the handle and escutcheon, and a deep-set stem often needs a tub-and-shower valve socket wrench. Most tub valves have no local shutoff, so turn the water off at the in-wall stops or the main before you start.
- Is a faucet repair kit worth buying if I rent?
- Check your lease before you touch it. In most tenancies the landlord is responsible for plumbing repairs, and doing the work yourself can void that obligation or breach the agreement. If your landlord agrees to let you handle it, a universal kit is the right choice for a rental: it fixes the drip without knowing the faucet brand and leaves the fixture itself unchanged.
