King valve replacement cost typically runs from a few dozen dollars for a simple ball valve swap to several hundred dollars for a main shutoff or curb stop replacement. This article lists realistic USD ranges, per-unit part pricing, and the most common cost drivers buyers see when getting a King valve replaced.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic indoor ball/gate valve replacement | $40 | $120 | $300 | Parts $20-$80; 0.5–2 hours labor |
| Main house shutoff or curb stop replacement | $200 | $450 | $1,200 | Includes excavation or pipe rerouting in some cases |
| Soldered copper or lead service valve | $150 | $350 | $800 | May require brazing or new service line work |
How Much Most Homeowners Pay To Replace a King Valve Inside the House
Typical total: $40-$300 depending on valve type, access, and material.
Simple indoor replacements (ball or gate valves on supply lines) assume standard 1/2″–3/4″ copper or PEX, normal access, and one plumber for 30–90 minutes. Parts run $20-$80; labor $75-$150 per hour. Assumptions: Midwest labor rates, standard materials, normal access.
Cost Breakdown: Parts, Labor, Equipment, Permits, and Disposal
Estimate the quote by adding line items for materials, labor, and any special equipment or permits.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $20-$400 (valve $20-$150; fittings $5-$200) | $75-$150 per hour; 0.5-6 hours | $0-$200 (soldering rig, extraction tools) | $0-$150 (municipal permit for service work) | $0-$150 (soil disposal, hauling) |
Which Site and Valve Variables Drive the Final Quote Most
Location and diameter of the valve typically shift a quote by 30%-200%.
Key variables: pipe size (1/2″–3/4″ vs 1″–2″), valve type (ball/gate vs curb stop), and access. Example thresholds: replacing an indoor 1/2″ valve often < $200, while a 1″+ main service or curb stop replacement with excavation can exceed $600. Another driver: pipe material—copper soldered joints add $75-$250 vs PEX crimp connections $20-$100.
How Material and Connection Type Change Pricing
Copper soldering, corroded fittings, or lead service lines increase cost significantly compared with PEX or compression fittings.
| Material/Connection | Low | Average | High |
|---|---|---|---|
| PEX with crimp/expander | $40 | $100 | $250 |
| Copper with sweat/solder | $100 | $275 | $700 |
| Bronze/lead service or curb stop with excavation | $200 | $500 | $1,200 |
Practical Ways To Reduce King Valve Replacement Price
Control scope and prep work to avoid surprise excavations and overtime charges.
Suggestions: expose and clear the valve area before the plumber arrives, confirm pipe size and material from photos, avoid emergency calls outside business hours, and choose a local licensed plumber with reviews rather than a high-markup emergency service. For non-critical valves, consider timed replacement during other plumbing work to bundle labor.
Regional Differences and Typical Timeframes To Budget For
Expect 10%-35% higher labor charges in coastal or urban markets and 20%-40% longer scheduling during peak seasons.
Example deltas: urban Northeast/West Coast +15%-35% above Midwest averages; rural areas often -5%-15%. Typical job durations: basic indoor valve 30–90 minutes; main service or curb-stop replacement 3–8 hours (includes excavation/backfill).
Extra Charges, Add-Ons, and When Permits Appear on the Quote
Permits, water service disconnection, or asphalt/landscaping repair commonly add $100-$900 to the invoice.
Common extras: permit fees $0-$150, emergency or after-hours fees $75-$250, asphalt cutting and patching $300-$900, and pressure testing or certification $50-$200. Always ask the contractor which extras are included in a written estimate.
Three Real-World Quote Examples With Specs and Totals
Examples help translate ranges into realistic line-item estimates.
| Scenario | Specs | Labor Hours | Total |
|---|---|---|---|
| Indoor bathroom shutoff | 1/2″ ball valve, PEX, easy access | 0.5 | $85-$140 |
| Main house shutoff under slab | 1″ copper, access via crawlspace, solder | 3 | $350-$700 |
| Curb stop replacement | 1″ service valve, excavation, new compression fitting | 6 | $650-$1,200 |
For budgeting, get 2–3 written quotes and confirm whether parts, excavation, and patching are included.
