How to Insure a Truck-Mounted Jetter Without a Coverage Gap (2026 Process)

Why a Jetter Is an Insurance Problem That Most Plumbers Get Wrong

A truck-mounted sewer jetter is one of the most expensive and risk-loaded pieces of equipment a plumbing contractor will ever buy. A new mid-size unit — Spartan, US Jetting, Harben, Sewer Equipment Co. — runs $18,000 to $45,000 for the jetter package alone, mounted on a $55,000 to $95,000 service truck or chassis. Premium units like a Vactor or Vac-Con go well into six figures.

It's expensive. It's mobile. It moves between job sites daily. It operates at 4,000 PSI with 18 GPM of water flow. And the work it does — clearing sewer lines, breaking up roots, pushing waste downstream — creates a pollution exposure that no Business Auto Policy or General Liability policy is designed to cover.

Most plumbers buy a jetter, ask their agent to "add it to the truck policy," and assume they're done. They're not. Here's the right process.

Step 1: Determine the Total Insurable Value of the Jetter Unit

Before any policy decision happens, document exactly what you have. For a truck-mounted jetter, the total insurable value is the sum of:

• The chassis / truck — VIN, year, make, model, mileage, ACV or replacement cost
• The jetter package — brand, model, engine HP, pump GPM/PSI rating, hose reel size, hose length, water tank capacity
• Mounted accessories — nozzles, locator equipment, work lights, hose guides, generator, water-heater if equipped
• Auxiliary equipment carried on the truck — sewer camera, locator, smaller hand-snake units, tools

For a typical fleet plumbing jetter rig, you'll arrive at something like:

Component	Typical Value
2024 Ram 5500 chassis with utility body	$72,000
US Jetting 4018 trailer-mount jetter package (truck-mounted)	$38,000
Ridgid SeeSnake Compact C40 camera with monitor	$8,500
Locator (Rycom or RIDGID NaviTrack)	$3,200
Nozzles, hose guides, lights, accessories	$2,800
Total insurable value	$124,500

Write this down. You'll reference it three times before the policies are in force.

Step 2: Cover the Truck Chassis on Your Business Auto Policy

The chassis — the truck itself — goes on your Business Auto Policy (BAP) like any other vehicle in your fleet. Add it with:

• Symbol 7 — specifically scheduled owned auto
• Liability limits matching your fleet standard (typically $1M CSL minimum for plumbing fleets)
• Physical damage — comprehensive and collision with $1,000–$2,500 deductible
• Declared value at chassis replacement cost (NOT chassis + jetter — see step 3)

This part is straightforward. Your agent adds the VIN to the schedule, the BAP rates it as a heavy service vehicle, and you get an ID card. Where plumbers go wrong is when they try to also insure the jetter on the BAP.

Why you should NOT put the jetter value on the BAP

You can list a higher declared value on the BAP and technically cover the jetter as "permanently attached equipment" — but you shouldn't, for four reasons:

1. Coverage geography — BAP physical damage only triggers when the truck is operating as a vehicle. If the truck is parked at a job site and the jetter is stolen off the bed, or if vandalism destroys the jetter while the truck is in the shop yard, your BAP claim gets contested.
2. Off-truck coverage — many jetter units come off the truck for service, repair, or to be transferred between vehicles. Inland marine covers the equipment wherever it is; BAP doesn't.
3. Replacement-cost vs ACV — most BAP physical damage policies pay actual cash value. Most inland marine policies pay replacement cost. On a 5-year-old jetter, that's a $15K–$25K coverage difference at the moment of loss.
4. Claims complexity — when the truck and jetter are damaged in the same incident (collision rolls the truck and destroys the jetter), splitting the BAP and inland marine claims runs cleaner with two carriers / two policies than trying to pull a $124K total loss out of a single BAP.

Step 3: Schedule the Jetter on a Contractor's Equipment / Inland Marine Policy

This is where most plumbers leave money on the table — or, more accurately, leave their jetter uninsured against the most likely loss scenarios.

A contractor's equipment floater (a type of inland marine policy) covers mobile equipment wherever it is — on the truck, off the truck, in the yard, at a job site, in transit, being repaired, or temporarily stored.

For a plumbing fleet running 1–3 jetters, you have two options:

Option A: Scheduled inland marine — list each item by description and value

Best for plumbing shops with a small number of high-value pieces. Each jetter, camera, and locator is listed by serial number, with its individual replacement-cost value. The policy covers exactly what's scheduled.

Pricing: roughly $0.75 to $1.50 per $100 of insured value. A $40,000 scheduled jetter runs $300–$600/year.

Option B: Blanket inland marine with sub-limits

Best for larger plumbing fleets with multiple jetters, multiple cameras, multiple locators, and hundreds of smaller tools. Set a blanket limit (e.g. $500,000 total) with sub-limits per item ($50K max per scheduled item, $5K max per unscheduled tool).

Pricing: roughly $0.50 to $0.90 per $100 of blanket limit. A $500K blanket runs $2,500–$4,500/year and covers your entire equipment program.

What the inland marine policy should specifically include

• Replacement-cost valuation — not ACV
• Worldwide coverage territory (or at minimum U.S. + Canada)
• Theft, vandalism, fire, collision, overturn, and flood as covered perils
• Off-truck coverage — equipment is covered when removed from the vehicle
• Newly acquired equipment endorsement — automatic 30–60 days of coverage on new equipment up to a sub-limit (typically $25K–$50K) before formal scheduling
• Borrowed/leased/rented equipment endorsement — coverage for jetters rented from a peer or rented while yours is in repair
• Equipment breakdown — optional but worth considering for high-cycle jetters (pump failure, engine seizure)

Step 4: Close the Pollution Gap With Contractor's Pollution Liability

This is the step almost no plumber gets right on the first policy renewal.

Your BAP covers the truck. Your inland marine covers the jetter. Neither covers the work the jetter does. When a jetter operates inside a customer's sewer line and something goes wrong — back-flow into a basement, ejected debris into a yard, a damaged line that leaks waste into groundwater — the resulting claim is a pollution claim. And the standard GL policy excludes pollution via the absolute pollution exclusion in the ISO CG 00 01 form.

The fix is a Contractor's Pollution Liability (CPL) policy. For a plumbing fleet operating jetters, the CPL needs to specifically include:

• Sudden and accidental pollution events caused by sewer/drain cleaning operations
• Backup and overflow of sewage at customer locations
• Property damage from ejected waste, debris, or contaminated water
• Bodily injury from exposure to sewage or contaminated water
• Cleanup costs — third-party and first-party (your own remediation expenses)
• Defense costs outside the limit ideally — pollution defenses are expensive and you don't want them eroding the limit

Pricing for a plumbing fleet CPL runs $2,500 to $7,500/year for a $1M occurrence / $2M aggregate limit, depending on revenue size, jetter operations frequency, and prior loss history. For deeper detail on CPL specifically, see our CPL for plumbers deep dive.

Step 5: Verify the Three Policies Don't Overlap or Leave Gaps

Once you have the BAP, inland marine, and CPL bound, do a coverage-mapping exercise. For each of the following scenarios, identify which policy responds:

Scenario	Policy That Responds
Truck collision damages truck and jetter	BAP (truck) + Inland Marine (jetter)
Jetter stolen overnight from job-site truck	Inland Marine
Jetter pump catastrophic failure from overload	Inland Marine (if equipment breakdown is endorsed)
Sewer backup into customer's basement during jetting	CPL
Operator slips on wet pavement on a customer's driveway	WC (operator injury) + GL (customer property damage)
Jetter hose whip injures a bystander	GL (bodily injury — non-pollution)
Vandalism damages jetter at customer site	Inland Marine
Diesel fuel spill from chassis tank into a storm drain	CPL (some states) + BAP MCS-90 endorsement (if hazmat-rated)

If any scenario above produces a "not sure" or "I'd have to check," that's a coverage gap. Fix it before the renewal pays the agent a commission.

Step 6: Verify Driver Qualifications and Endorsements

A truck-mounted jetter rig often crosses into CDL territory depending on chassis GVWR, water tank size, and trailer status. A Ram 5500 with a full water tank can hit 19,500 lbs GVWR — under the 26,001 lb federal CDL threshold but pushing local commercial-license requirements in some states.

Before the policy binds, confirm:

• Every driver assigned to the jetter truck has the correct license class for the state of operation
• The driver's MVR is acceptable to the carrier (typically no major violations in 3 years, no DUI in 5)
• The driver has documented training on jetter operation, hose handling, and confined-space safety
• You've added the driver to the BAP driver schedule within the carrier's notification window (usually 30 days)

Most "we never thought of that" coverage gaps on jetter claims trace back to an unauthorized driver behind the wheel, not a policy form problem.

Step 7: Document Operating Procedures (Required by Some Carriers)

Carriers like Federated and Travelers will request written operating procedures for jetter-equipped plumbing fleets, especially above 3 units. The procedures should cover:

• Pre-job site survey (locate clean-outs, check vent stacks, identify low fixtures)
• Pressure ramp-up protocol (start at 1,500 PSI, increase as needed)
• Backflow prevention practices (using a downstream block, monitoring for backup)
• Customer communication and warning (notify before starting, identify floor drains and fixtures at risk)
• Spill response protocol if a backup occurs
• Post-job verification and customer sign-off

Having this in writing produces underwriting credits at most carriers (typically 5–10% off the GL and CPL) and substantially improves claim outcomes if a sewer backup loss does occur.

The Complete Jetter Insurance Stack — Recap

Coverage	What It Insures	Typical Annual Cost
BAP (truck portion)	Chassis liability and physical damage	$1,800–$2,400 per vehicle
Inland Marine (jetter scheduled)	The jetter itself, anywhere, replacement cost	$300–$600 per $40K scheduled
CPL ($1M / $2M)	Pollution liability from sewer/drain work	$2,500–$7,500 for the fleet
GL (general liability)	Non-pollution third-party BI and PD	Already in fleet program
WC (workers' comp)	Operator injuries	Already in fleet program

For a single jetter truck added to an existing 10-truck plumbing fleet, the marginal annual cost is roughly $2,500–$3,500 when you do it properly: $2,000 of BAP, $500 of inland marine, and a $500–$1,000 incremental bump to the CPL (since the CPL is usually already in force for the fleet).

Doing it wrong — putting the jetter on the BAP only and skipping CPL — saves about $1,000/year. The first sewer backup claim that lands on a CPL-less plumbing fleet erases 10 years of that savings in a single afternoon.
