A Price Pfister 910-900 cartridge typically costs about $20-$60, while a plumber-installed replacement commonly totals $170-$400. The final price depends on whether the cartridge is new, used, or a compatible substitute, plus local labor rates, valve condition, and whether the faucet or shower trim must also be removed.

What a Pfister 910-900 cartridge replacement usually costs
For the part alone, buyers can budget roughly $20-$60 for a 910-900 cartridge, with an average online or local retail price near $38. Availability can be uneven for an older or less commonly stocked model. A listing that appears inexpensive may be for a used, open-box, or unverified part, so check the product number and return policy before ordering.
A straightforward DIY replacement generally comes to $25-$100 after allowing for the cartridge, plumber’s grease, and a basic removal tool if needed. A plumber’s total is more often $170-$400, including a service-call minimum and roughly one to two hours of work. In a high-cost metro area or on a difficult repair, the bill can exceed $400.
The estimate assumes the existing valve body remains usable and the replacement matches the faucet or shower valve. The 910-900 number alone is not enough to establish compatibility for every Pfister fixture; confirm the full model number, trim style, and cartridge appearance. Labor formula:
How the cartridge, labor, and service call shape the quote
A replacement estimate usually combines the part, technician time, and the cost of getting a plumber to the property. Extra charges are possible if a trim kit, handle, or damaged valve component must be replaced. The service-call minimum can matter more than the cartridge’s retail price.
| Quote component | Typical charge | What it covers | When it increases |
|---|---|---|---|
| Cartridge | $20-$60 | New 910-900 or compatible replacement | Scarce stock, expedited shipping, verified OEM part |
| Plumber labor | $90-$250 | About 1-2 hours at roughly $75-$150 per hour | Stuck cartridge, difficult access, extra diagnosis |
| Service call | $50-$125 | Travel and minimum dispatch charge | After-hours call or long travel distance |
| Small supplies | $5-$30 | Grease, seals, fasteners, or minor fittings | Corroded or damaged supporting parts |
| Disposal or cleanup | $0-$25 | Removal of the old cartridge and work-area cleanup | Usually bundled into labor |
These line items do not always appear separately. Some plumbers quote a flat $175-$350 for a routine cartridge change, while others list the dispatch fee and labor as distinct charges. Ask whether the quote includes the part, diagnosis, cleanup, and a return visit if the supplied cartridge does not fit.
Which 910-900 compatibility and valve problems raise the price?
The largest cost risk is ordering a cartridge that does not fit. Pfister has used different cartridges across faucet and shower generations, and sellers may use similar product descriptions. Compare the old part’s shape, length, stem, seals, and any markings with the replacement listing; use the fixture’s model information when available. A confirmed fit can prevent a second service call and another $50-$125 dispatch charge.
Valve condition also changes labor. If the cartridge pulls out cleanly, replacement may take around 45-90 minutes. A cartridge seized by mineral scale or corrosion can add one to two hours, raising labor by approximately $75-$300 at common hourly rates. An extractor tool or careful removal may be needed to avoid damaging the valve body.
Hard-water buildup can make a new cartridge leak or operate poorly if debris remains in the valve. A flush and cleaning may add $25-$100, depending on access and the plumber’s minimum charge. If the valve body is cracked, badly corroded, or damaged during removal, the repair may become a larger faucet or shower-valve job, often $350-$900 or more depending on wall access and finish work.
Fixture type and access matter. A sink faucet with open cabinet access is usually simpler than a shower valve behind a tight escutcheon or finished wall. If the valve must be opened through tile or drywall, the plumbing quote may not include patching, tile replacement, or painting; those finish repairs can add $100-$600 or more.
Is DIY replacement cheaper than hiring a plumber?
DIY makes the most financial sense when the fixture is accessible, the correct part is confirmed, and the shutoff valves work. The likely outlay is $25-$100, compared with roughly $170-$400 for a professional visit. DIY savings are greatest when the cartridge releases without force and no valve-body repair is needed.
Before starting, shut off the water supply and protect the drain from small parts. Photograph the handle and trim as they come off, and keep screws and adapters in order. Use the removal method appropriate to the fixture; excessive force can damage the valve or plumbing connections. If the cartridge will not move with reasonable effort, stopping is usually less expensive than breaking a valve that requires more extensive access.
DIY may be a poor bargain when the shutoff valves are stuck, the fixture is in a finished shower wall, or the cartridge identity is uncertain. A plumber can diagnose the valve and source a compatible part, but confirm whether the diagnostic fee is credited toward the repair. A second trip for a wrong part can add $50-$125 or more, especially if the original visit is billed separately.
How plumber rates and location change the installed price
Rates vary by local wages, business overhead, travel distances, and appointment demand. A routine cartridge replacement in a lower-cost rural or small-town market may land near $150-$250. In many suburbs and mid-sized cities, $200-$350 is common; major metros and high-cost coastal markets may run $275-$450 for the same basic scope.
Those differences reflect both hourly pricing and minimum charges. A plumber billing $75-$100 per hour may still charge a $100-$175 minimum for a short visit. In expensive cities, rates of $125-$200 per hour are possible, and dispatch or parking costs may be added. Compare the complete installed quote, not just the hourly rate.
After-hours calls can raise labor or dispatch charges by 25%-100%, and weekend appointments may carry a premium. If the faucet can be shut off safely and the leak is not causing damage, a standard-hours appointment may avoid the surcharge. Ask whether the quoted price is fixed for the repair or subject to additional charges after inspection.
What three common 910-900 replacement quotes include
A simple DIY case might involve a confirmed $35 cartridge and $10 in supplies, for a total near $45. This assumes a working shutoff, easy access, and a cartridge that can be removed without special equipment. The owner’s time is not included, and a wrong part could add shipping or return costs.
A standard plumber visit might list a $38 cartridge, 1.25 labor hours at $110 per hour, and a $65 service charge. That example totals about $241 before tax, if applicable. It assumes an accessible fixture, normal weekday scheduling, and no damaged valve parts.
A difficult shower repair could include a $55 cartridge, three hours of labor at $145 per hour, and a $95 dispatch fee, totaling about $585 before any wall repair. The added time could reflect a seized cartridge or careful work around older trim. Ask whether a high estimate includes only plumbing or also restoration of the surrounding wall.
When replacement parts or valve repairs add to the bill
A handle, trim plate, or seal may need attention if it is broken or worn, but these items should not be added automatically to a cartridge quote. Minor seals and grease commonly add $5-$30 in materials; a compatible handle or trim component can add $20-$150 or more depending on availability and finish. Request the reason and part price for each proposed add-on.
If the valve body itself has failed, replacing only the cartridge may not stop a leak. A plumber may recommend a valve repair or replacement instead, with costs ranging from about $350-$900 for accessible work and potentially $800-$1,800 or more when a shower wall must be opened and restored. Get separate pricing for cartridge-only work and any proposed valve replacement.
For older fixtures, the choice may be between locating a verified cartridge and replacing the faucet or shower valve with a current model. A basic faucet replacement may cost $200-$600 installed, while a shower-valve replacement can cost substantially more because of plumbing access and finish work. Compare the full project price, not merely the price of a new fixture.
How to lower the Pfister cartridge repair quote
Confirm the fixture model and cartridge before booking, and share clear photos of the handle, trim, and old cartridge if it has already been removed. This can help the plumber bring the right part and reduce the chance of a second visit. Accurate identification and a clear repair scope are the most practical ways to control the bill.
Ask for an itemized quote showing the part, service call, labor allowance, and any diagnostic or after-hours fees. Get two or three local estimates for the same scope, and check whether each includes the cartridge and cleanup. A low labor figure may not be the lowest total if the service fee or parts markup is high.
Schedule during regular business hours when the leak can be safely contained. Avoid approving new trim or a complete valve replacement unless inspection shows it is necessary, and ask whether cleaning or cartridge-only replacement is a reasonable first repair. If other plumbing work is already scheduled, combining visits may reduce duplicate dispatch charges, though the added work should still be priced separately.
