5 Best Kitchen Faucet Parts Price Pfister Options for Easy Repairs (2026)

Updated November 2026

Shopping for kitchen faucet parts from Price Pfister usually starts with a single problem: a drip, low flow, a stiff handle or a faucet that suddenly runs hot and cold backward. Replacing the right component can save a full faucet swap, but only if the part matches your model’s valve type and thread size. The five picks below were selected by reviewing manufacturer specifications, the part names and model series they fit, and the patterns owners commonly describe in replacement threads. Selection criteria were compatibility clarity, the function each part serves, and how often the part is the actual cause of a common kitchen faucet fault. We did not test these parts ourselves; the notes reflect published specifications and general owner feedback.

Pfister Pfirst Series Kitchen Pull Down Faucet Sprayer, Stainless Steel

Best for: Replacing a worn or leaking pull-down sprayer assembly.

This is the right choice for homeowners whose main faucet body still works but whose sprayer hose, head or docking area has failed. It suits people who want to keep the existing Pfister body and avoid replacing the whole fixture.

Key specs

• Pull-down sprayer assembly for the Pfirst Series
• Stainless steel finish
• Designed as a replacement sprayer rather than a full faucet

Pros

• Matches a common Pfister series, which simplifies compatibility checks
• Stainless construction is a popular choice for durability in kitchens
• Lets you fix the sprayer without draining the whole faucet system

Cons

• Only useful if your faucet is from the same series
• Installation requires checking hose routing and fittings under the sink

Bottom line: Best for owners of a Pfirst-style pull-down faucet whose sprayer, not the valve, has failed.

Pfister 9740740 Avalon/Treviso 26/529 Series 25mm Cartridge Sub Assembly

Best for: Full cartridge replacement on compatible Avalon and Treviso series faucets.

Best suited to people who have confirmed their faucet uses a 25mm cartridge and want a complete sub assembly rather than a loose seal kit. Owners often describe it as the more reliable route when a cartridge is worn throughout.

Key specs

• 25mm cartridge sub assembly
• Designed for the Avalon/Treviso 26/529 series

Pros

• Complete assembly removes guesswork about worn internal parts
• Series-specific naming makes compatibility checks straightforward
• Usually quicker than disassembling and rebuilding an old cartridge

Cons

• Fits only specific series; a wrong size will not seat
• Requires shutting off water and removing the handle to install

Bottom line: Pick this if your faucet is confirmed as an Avalon or Treviso 25mm model and the cartridge is the source of the leak.

Pfister 9100320 Cold Faucet Cartridge, Original Version

Best for: Fixing a dripping or stuck cold-water side.

Ideal for owners of two-handle Pfister faucets where only the cold side leaks or stops responding. Replacing just the single cold cartridge is usually cheaper in effort than replacing both sides.

Key specs

• Cold-side cartridge, original version
• Two-handle faucet application

Pros

• Targets the single failing side instead of the whole valve
• Original-version designation helps match older faucets
• Straightforward swap for a dripping cold handle

Cons

• Original and newer versions are not always interchangeable; check before buying
• Does not address hot-side issues or spout leaks

Bottom line: Best for a two-handle Pfister faucet with a leaking or hard-to-turn cold side.

Pfister 941-2930 1.75gpm Aerator Insert

Best for: Restoring weak or uneven flow at a low cost.

A good first step for anyone whose faucet spray has become weak, spotty or splashy. Clogged aerators are a frequent cause of reduced flow, and this is the simplest part to swap.

Key specs

• 1.75 gpm flow rating
• Aerator insert replacement

Pros

• Quick, tool-light replacement
• Flow rating is clearly stated for water-use planning
• Often solves low-pressure complaints without other repairs

Cons

• Does not fix leaks from handles or the base of the faucet
• Flow-rate needs may differ by household; confirm local requirements

Bottom line: The best starting point when the problem is flow, not leaks.

Price Pfister 974-035 Single Lever Ceramic Disk Cartridge

Best for: Stopping drips in single-lever Price Pfister faucets.

Suited to owners of single-handle faucets where water leaks from the spout even when the lever is off, or where the lever has become stiff and uneven. Ceramic disk cartridges are widely used for their smooth operation.

Key specs

• Single-lever design
• Ceramic disk cartridge

Pros

• Ceramic disks are a common choice for smooth, low-maintenance control
• Addresses the most frequent single-lever complaint: dripping
• Replaces the internal valve without replacing the faucet

Buying Guide

Confirm your faucet series and valve type

Before buying any Price Pfister part, identify the series name, model number and valve type printed on the faucet or in the original manual. Single-lever, two-handle and pull-down designs each use different components, and a part that looks similar can fail to seal.

Good picks for this: Pfister 9740740 Avalon/Treviso 26/529 Series 25mm Cartridge Sub Assembly, Price Pfister 974-035 Single Lever Ceramic Disk Cartridge

Cartridge size and thread compatibility

Cartridges are often sized in millimeters, commonly 25mm for many Pfister models. Measure the old cartridge’s diameter and note its height before ordering, and compare both against the listing.

Good picks for this: Pfister 9740740 Avalon/Treviso 26/529 Series 25mm Cartridge Sub Assembly, Pfister 9100320 Cold Faucet Cartridge, Original Version

Identify hot versus cold side repairs

On two-handle faucets, replacing only the failing side keeps the other side’s performance intact. Turn on each handle separately to see which side drips or sticks, and buy the cartridge for that side only.

Good picks for this: Pfister 9100320 Cold Faucet Cartridge, Original Version

Flow rate and aerator size

Aerators are rated in gallons per minute (gpm). A 1.75 gpm insert is a common match for many kitchen faucets, but check the rating printed on your current aerator or in your manual before replacing it, since some regions and fixtures specify different limits.

Good picks for this: Pfister 941-2930 1.75gpm Aerator Insert

Sprayer and hose condition

Pull-down sprayers wear at the hose, the docking magnet and the spray head. Inspect for kinks, cracks and weak retraction before assuming the valve is at fault. Sprayer assemblies are often the simpler and more economical repair.

Good picks for this: Pfister Pfirst Series Kitchen Pull Down Faucet Sprayer, Stainless Steel

Material and finish durability

Stainless steel components resist corrosion in damp kitchen environments better than many plated alternatives. Ceramic disk valves are favored for smooth operation and longevity. Look for these specifications in the listing before buying.

Installation and maintenance basics

Shut off both supply valves under the sink, relieve pressure by opening the faucet, and place a towel in the sink to protect fittings. Replace parts in pairs when one side has worn, and check for mineral buildup periodically to extend part life.

FAQ

Are all Price Pfister kitchen faucet parts interchangeable?

No. Parts are usually series-specific. Cartridges, sprayers and aerators can differ by model year and design, so always match the part to your faucet’s series and model number.

How do I know which cartridge my faucet uses?

Remove the handle and cap, then check the cartridge’s size and shape. Many Pfister models use 25mm cartridges, but measuring the old part is the most reliable check.

Can I replace just one aerator without other repairs?

Yes. A clogged or worn aerator can be unscrewed from the spout tip and replaced by itself. If the spray stays weak after cleaning or replacing it, the problem may be in the valve or supply line.

Should I replace the cartridge or the whole faucet when it drips?

In most cases the cartridge is the cause, and replacing it is far less work than a full faucet swap. If the faucet body is corroded or the spout is cracked, a full replacement may make more sense.

Do I need to shut off the water before replacing parts?

Yes. Close the shutoff valves under the sink and open the faucet to drain remaining water before removing any component. This prevents spills and makes installation cleaner.

What if my faucet is not a Pfister or Price Pfister model?

These parts are designed for specific Pfister series. For other brands, look for the manufacturer’s replacement list or consult a plumbing supply professional to confirm the correct part.

Conclusion

For a leaking single-lever faucet, the Price Pfister 974-035 Single Lever Ceramic Disk Cartridge is the most direct fix. Two-handle cold-side drips point to the Pfister 9100320 Cold Faucet Cartridge, while a full valve rebuild on a matching Avalon or Treviso fixture suits the Pfister 9740740 sub assembly. Weak flow is most often solved by the Pfister 941-2930 aerator, and sprayer failures are best addressed with the Pfirst Series pull-down sprayer. Confirm your series and valve type before ordering, and if a repair involves gas, electrical work or unfamiliar plumbing, consult a licensed plumber.
