Pfister Faucet Repair Parts: Which Stem, Seat or Cartridge You Need
Pfister faucets, many of them still stamped Price Pfister, use several kinds of repair parts. An older two- or three-handle tub and shower valve uses brass compression stems that close against a brass seat. A single-handle tub and shower valve in the 0X8 family uses one pressure balance cartridge. Many single-handle sink faucets use a cartridge too, and a bathroom sink with a lift rod has a pop-up stopper. A drip can come from any of them, so the first job is knowing which kind of faucet you have.
This guide shows how Pfister says to identify a faucet, which part goes where, and the look-alike part numbers that trip people up. For a full index of Pfister part numbers with sizes, our sister site keeps a Pfister stems and cartridges index.
Step 1: Identify your faucet the way Pfister does
- Look for the model number. Pfister's FAQ says the product model number, usually an 8 digit code such as F-529-7AYY, is on the product package.
- For a tub and shower valve, look on the valve itself. Pfister says to remove the trim plate and look for markings or model numbers on the valve body. Its FAQ names valve series such as 0X8, 0X6, 0X9 and JX8.
- For a sink faucet, Pfister suggests checking under the sink to see if your product has a label on either the supply line or the shank.
- Still not sure? Pfister says to send a photo of your faucet and it will identify it for you, and lists its support line as 1-800-PFAUCET.
Then count the handles. The Pfister single-handle tub and shower valves in this guide, the 0X8 family, use one cartridge. The two- and three-handle tub and shower valves in this guide use compression stems, and on a three-handle valve the middle handle is the diverter that sends water up to the shower head.
Step 2: Match the part
| What you have | The Pfister part | What to check |
|---|---|---|
| Hot or cold handle on a two- or three-handle tub and shower | 910-374 Marquis stem | A Pfister-brand listing says it fits 2 or 3-handle Price Pfister faucets and can be used for hot or cold sides. A Crown Imperial faucet takes the 910-013, a different stem. |
| Center handle on a three-handle tub and shower | 910-382 diverter stem | A Pfister-brand listing describes it as a diverter stem with external threads, for faucets with a sleeve. Pfister-brand listings call the 910-385 the Marquis diverter, and the 910-022 is another diverter, so compare your old stem first. |
| The seat under a tub and shower stem | 970-500 seat | Ferguson lists it as a 21/32 x 18 valve seat for tub and shower. |
| The seat under a kitchen or bathroom sink stem | 970-510 seat | Ferguson lists it as a 1/2 in. x 20 compression seat for kitchen and lavatory faucets. |
| Single-handle tub and shower, valve stamped 0X8, JX8, VB8 or JV8 | 974-042 cartridge | Ferguson lists the 974-042 as a pressure balance cartridge for 0X8, JX8, VB8 and JV8 valves, and Lowe's calls it a 1-piece cartridge. |
| Bathroom sink stopper worked by a lift rod | 972-691A pop-up stopper | Lift the old stopper out and compare it before you order. |
Part descriptions from the Pfister-brand listings at The Home Depot and from Ferguson, as listed under Sources. We could not open a Pfister product page for these stems, seats or the stopper.
Hot and cold stems: 910-374, and the 910-013 look-alike
The 910-374 is the hot and cold stem for Pfister Marquis two- and three-handle tub and shower faucets. The Pfister-brand listing at The Home Depot says it is compatible with 2 or 3-handle Price Pfister faucets and can be used for hot or cold sides in multi handle faucets, and Jones Stephens sells its replacement as a hot and cold stem for Pfister Marquis and Verve.
The 910-013 is a separate part. The Pfister-brand listing calls it the Crown Imperial hot and cold replacement stem, retailers list it as the shorter of the two, and Jones Stephens sells a different replacement for it. None of the sources we read says the two interchange, so match the stem that came out of your valve, by length and by the splines on top. Our own 910-374 replacement is for the 910-374 only.
A stem that is in good shape can often be rebuilt instead of replaced. Our 5 piece kit for the 910-374 renews the wearing parts on one stem: a 21/32 x 18 brass seat, a flat stem washer, a brass washer screw, a cap thread gasket and the bonnet packing.
Diverter stems: 910-382, 910-385 and 910-022
On a three-handle Pfister tub and shower, the center handle turns a diverter stem that sends the water to the spout or up to the shower head. Pfister made more than one. The Pfister-brand listing at The Home Depot describes the 910-382 as a diverter stem with external threads and outside bonnet threads for faucets with a sleeve. Pfister-brand listings describe the 910-385 as the Marquis replacement diverter stem and the 9103850 as a 12-point diverter for Verve and Windsor faucets. HD Supply lists the 910-022 as a diverter for three-handle tub and shower valves, and it appears with the 910-013 in Pfister's parts list for its 01 series valve.
Retailer cross-references for these three disagree with each other, so do not go by a part number alone. Pull the old diverter and compare it with the new one, end to end. If water comes out of the spout while the shower is on, our guide to water coming out of the tub spout when the shower is on walks through the diverter checks first.
Seats: 970-500 for the tub, 970-510 for the sink
Each compression stem closes a rubber washer against a brass seat threaded into the valve. This Old House says that when you replace a worn valve stem you should also replace the seat, and its pro tip warns that skipping this step can mean your new stem wears out faster. Pfister uses two common seats, and they are not interchangeable:
- The 970-500, listed by Ferguson as a 21/32 x 18 seat for tub and shower valves. Danco says its #38 seat replaces Price Pfister 970-500, old number 5713. Pfister-brand listings note the 910-385 diverter works with the 970-500 seat.
- The 970-510, listed by Ferguson as a 1/2 in. x 20 compression seat for kitchen and lavatory faucets.
A seat comes out with a seat wrench turned counterclockwise, as Danco says. Pfister's own three-handle upgrade guide lists a 5/16 in. square seat wrench among its tools. Measure the thread on the seat that came out before you buy.
Single-handle tub and shower: the 0X8 family cartridge
Pfister's care guide lists the 0X8 and JX8 as single control pressure balancing valve bodies. Ferguson lists the Pfister 974-042 as a pressure balance cartridge for 0X8, JX8, VB8 and JV8 valves, and Lowe's describes it as a 1-piece cartridge with an integrated temperature limit stop. Ferguson now lists the 974-042 as discontinued and replaced by the 974-5299, which it calls backwards compatible with legacy 0X8 and JX8 cartridges.
To confirm the family, take off the handle and trim plate and read the stamp on the valve body, as Pfister's FAQ says. On our part page we list the signs we see most: the spout drips with the handle off, the shower turns cold when a toilet flushes, or the handle goes stiff.
Pfister also uses cartridges in many single-handle sink faucets. The Pfister 974-044, for example, is a 35 mm hot and cold cartridge listed as compatible with Pfister 1-handle faucets. We do not sell a Pfister sink cartridge, so take the old one to the store or ask Pfister to identify it.
Bathroom sink: the 972-691A pop-up stopper
A Pfister bathroom sink with a lift rod behind the faucet uses a pop-up stopper that the pivot rod passes through. Stopper sizes differ, and the sources we read give different lengths for this one, so lift the old stopper straight out and compare it with the part page before you order. Our guide to replacing a pop-up sink stopper shows the swap.
Taking a Pfister stem out
Pfister's instructions start by shutting off the water supply valves, and its care guide for 0X8 and JX8 valves says to turn off water supplies and relieve pressure before working. Pfister's upgrade guide says those supply valves are usually found near the water meter, and This Old House shuts the water off at the main for a three-handle valve. Do not force a stem that will not turn: a stem that breaks off in the valve is a plumber's job, which is our own advice.
- Shut off the water and open the faucet to relieve the pressure.
- Take off the handle. This Old House removes the screw holding the handle in place and pulls the handle free of the valve stem.
- Take off the trim. This Old House unscrews and removes the escutcheon by hand to expose the stem.
- Turn the stem out. Pfister's upgrade guide says to be sure the stems are in the full on position and the water is turned off before removing them. This Old House uses a valve socket and pliers, and Danco turns the stem counterclockwise with a wrench until it threads out entirely.
- Check the seat, and replace it with a seat wrench if it is worn, as above.
- Fit the new or rebuilt stem. Danco threads a brass stem in clockwise until it threads entirely and then tightens it with a wrench. Everbilt's kit listing recommends plumbing grease on the seals when you reassemble.
- Put the trim and handle back, turn the water on and check for drips at the spout and around the handle.
When to stop and call a plumber
Each of these is our own advice, not a maker rule.
- The water will not shut off at the stops or the main.
- A stem or seat will not turn, or the wrench starts to round it off.
- The faucet body moves inside the wall when you turn the stem.
- Water is leaking inside the wall, not only from the spout or the handle.
Frequently asked questions
Is Price Pfister the same brand as Pfister?
Yes. In a May 2011 press release, Pfister said the brand had decided to simplify its name to Pfister. The company began in 1910 as Price Pfister, named for its founders Emil Price and William Pfister, which is why older faucets and many parts are still labeled Price Pfister.
Will a 910-374 stem replace a 910-013?
Do not count on it. Every source we found treats them as different stems: Pfister-brand listings call the 910-374 a Marquis stem and the 910-013 a Crown Imperial stem, retailers list the 910-013 as the shorter of the two, and Jones Stephens sells a separate replacement for each. Match the stem that came out of your valve.
Which Pfister seat do I need?
It depends on where the faucet is. Ferguson lists the Pfister 970-500 as a 21/32 x 18 valve seat for tub and shower, and the 970-510 as a 1/2 in. x 20 compression seat for use in kitchen and lavatory faucets. They are different threads, so measure the seat that came out.
My valve took a 974-042 cartridge. Is that still made?
Ferguson lists the Pfister 974-042 as discontinued and points to the 974-5299, which it describes as backwards compatible with legacy 0X8 and JX8 cartridges. Other retailers still list the 974-042. Our replacement is for Pfister single-handle valves stamped 0X8, JX8, VB8 or JV8, so read the stamp on the valve body behind the trim first.
How do I count the splines on a stem?
Danco says to count the number of splines around the top of the stem, and to darken one spline first with a black permanent marker so you know where you started. Retailers list a 12-point broach for the Pfister 910-385 and for replacements of the 910-374. Count yours and compare it with the old handle as well.
